"PROCESS FOR PRODUCING LAMINATED ORNAMENTAL.GLASS" Invention Title Details of Associated Provisional Applications Nambers The following statement is a full description of the invention including the best method of performing it known to me.
TITLE OF THE INVENTION: PROCESS FOR PRODUCING LAMIATED ORh'AMENTAL GLASS BACKGROUND OF THE INVENTION This invention relates to a process for producing laminated ornamental glass which utilizes computer integrated manufacturing technique instead of conventional printing methods to have coating layers with desired painting or pattern printed or coated onto the glass substrate of the laminated ornamental glass in a more efficient and economical way than conventional processes.
As living standards improve, people are paying more attention to the construction of outer walls of buildings, windows and doors as well as interior decoration, furniture and S partitions, with corresponding regard to luminosity, safety and privacy.
Conventionally, the ornamental glass for an interior partiion, such as a screen or an inlaid plate of wall, is prepared by printing a desired colored pattern directly onto a single shee of glass, reprinting on or adhering by an adhesive directly to a glass substrate a desired colored pattern which is printed in advance on a resin film or paper, or (3) printing a desired pattern of ceramic color frit onto a single sheet of glass followed by heat treatment and then coating a varnish on or adhering a resin film to said printed glass as a protective layer. As to the first two methods of producing conventional ornamental glass,, the desired colored pattern printed by such methods on one of the surfaces of a single sheet of glass is exposed to the air, and is therefore subject to 1 I aSbC~ sunlight or oxidation so that the color of said pattern will change and fade, as well as being subject to damage when cleaning. In addition, among these aforementioned methods, some require a good printing technique for printing the desired colored pattern printed in advance of a resin film or paper on a sheet of glass, and glass-laminating skills for obtaining the desired delicate pattern as well as a bubble-free ornamental glass, so the cost of production is high. Moreover, the material of the colored pattern printed on conventional ornamental glass is an opaque glaze pigment, paint, oil ink or a mixture thereof oOs o S" 10 which after a period of time will fade away while being exposed to 0 Cg 0@ go.. sunshine (infrared ray or ultraviolet rays), so such ornamental glass *e o can only be used in doors.
0 Consequently, as disclosed in U. S. Patent No 5370913 which has been granted by the same applicant of the present invention, a laminated ornamental glass with three coating layers having pattern and figures printed or coated on the glass substrate thereof, which can be used indoors as well as outdoors, has been developed.
%Conventional printing methods or otherwise for coating layers o oo° having pattern and figures can no longer satisfactorily and economically meet the increased demand by consumers for a variety in the design of pattern and figures of the coating layers. In addition, conventional printing methods or otherwise are time-consuming and cannot meet the increasing demand for shortening the period of production. Therefore, solutions to the above problems are desirable.
S. ad: 0 0: 0:80 000 IBBI~l~s--Y SUMMARY OF ,.THE INVENTION An object of the present invention is to provide a process for producing a laminated ornamental glass which can be used indoors as well as outdoors, use is not restricted to interior partitions, screen walls or ornamental inlaid plates but includes outer walls of a building, curtain walls of constructions, and the glass of doors and windows which are transparent and heat-insulating under different conditions of luminosity.
Another object of the present invention is to provide a process for producing a laminated ornamental glass which can be composed of two sheets of transparent or light-coloured, flat or bent, reinforced glass or an ion exchange reinforced glass, in which one of the two sheets is selected from polyester or polycarbonate resin according to the use.
A further object of the present invention is to provide a process for producing a laminated ornamental glass which can be transairent and heat-insulating. It can be produced by directly printing or coating a glazed painting or striped-figure pattern coating layer by a color inkjet printer connected to a computer with a program of the design of the painting or pattern stored therein on the inner surface of the outwardly-facing glass substrate, a white paint coating layer and a black or grey oil ink coating layer then in turn being printed or coated over the glazed painting or striped-figure coating laye and engraving figures selected from circles, tetragons, or hexagons out of the coating layers by a laser engraving machine as well connected to aforesaid computer with a program of the design of the figures i I c~p~rrsr"~ bI LI116~E~ U~ r i Istored therein after the coating layers dried. Therefore, the transparency and indoor luminosity can be optionally adjusted to the desired degree by changing the ratio of the sizes of the coating layers to the crevice portions between the coating layers.
Still another object of the present invention is to provide a process for producing a laminated ornamental glass which can employ 2dhesive admixed with infrared or ultraviolet absorbents for absorbing infrared rays or ultraviolet rays to render a heat insulation effect or have embedded in it metallic wires or net making it theft-proof or explosion-proof and said glass may be thickened as desired to increase penetration resistance, high net crack, and sound insulation.
Still a further object of the present invention is to provide a process for producing a laminated ornamental glass which can be indoor-used or outdcor-used without needing to be made by highly skilled printing or glass-laminating techniques.
In other words, the aforementioned three coating layers formed by the glazed painting coating layer having intercrossing stripes or net configuration composed of circles or hexagons, the white paint coating layer and the black or grey oil ink coating layer can be coated or directly printed on the glass substrate simply by a conventional screen printing method, so that the laminated ornamental glass is easy to produce at a high production rate with a low rate of defecLs.
Still another object of the present invention is to provide a process for producing a laminated ornamental glass which can be I- I i -1 CL~C~ economically and efficiently produced by a computer integrated manufacturing method instead of conventional printing methods or otherwise.
The terms "array" is to be understood as including, for example, stripes which may be parallel, and the term "glass" is to be understood as including plastics materials.
DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the process for producing a laminated ornamental glass comprises: o 10 a) printing by a color inkjet printer an opaque, first o0 eo *coating layer having an image or striped-figure pattern on a first side of a first glass substrate, said image being produced by the color inkjet printed under control of a computer with said image or pattern stored therein; b) coating a second, white paint coating layer and a S•third, black or grey oil ink coating layer in turn over the first coating layer by conventional spray coating or roll coating method; after dried; c) engraving in an array or net, figures on said coating layers by a laser engraving machine under control of said computer *00004 with said figures stored therein, leaving transparent coating-free crevice portions between said opaque patterned coating portions; and d) laminating with adhesive a second glass substrate over the coating layers and the first glass substrate through the 7 licrevice portions to obtain the laminated ornamental glass.
-r It will be appreciated that the design of the desired glazed painting, striped-figure pattern, and the figures selected from the group consisting of circles, tetragons, and hexagons which are arranged in an array or net are designed and edited by means of the CAD/CAE technique and written into a computer program which is filed in a floppy disk or the hard disk of a computer.
In execution of the program, a first coating layer with desired glazed painting or striped-figure pattern can be directly printed S. onto the inner side of the outwardly-facing glass of this invention by a color inkjet printer connected to a computer with r o the aforesaid program stored therein. Likewise, after a second, white paint coating layer and a third, black or grey oil ink coating layer have been printed or coated over said first coating layer by conventional spray coating or roll coating method and dried, figures selected from the group consisting of circles, tetragons, and hexagons can then be engraved out of the coating oalm layers by a laser engraving machine connected to the computer o with aforesaid design program, leaving transparent coating-free o crevice portions between said opaque coating portions.
It will be appreciated that the coating-free crevice portions between the patterned coating layers are filled by the adhesive in the process of lamination which involves the application of heat and pressure.
It will also be appreciated that, because the first coating layer is printed on the irner surface of the outwardly-facing glass substrate, and the white paint coating layer is positioned between the aforesaid layer and the black or grey oil ink coating I layer, only the printing or coating pattern of the first coating layer rather than indo'or objects can be seen"when viewed from the outside of the building or room, whereas the black or grey coating pattern composed of for example circles or hexagons can be seen and outdoor objects can be seen through the coating-free crevice portions, when viewed from the inside of the building or room.
The interior luminosity is adjustable by simply changing the ratio of the sizes of the opaque coating patterns to the coating-free transparent crevice portions, for example, 9:1, 6.5:3.5, or 5:5, depending on the need to raise the rate of transparency from 3% to The glazed painting, white paint and oil ink employed for the opaque coating layers are primarily prepared by mixing conventional ceramic color frit such as CaO, MnO, CdS, Cr 2 0 3 or Fe 2 0 3 15 to 70 wt% with glass powder 30 to 85 wt% (the weight percentage is based on the total weight of the mixture obtained oo therefrom); most preferably the content of the ceramic color frit is no more than 30 wt% and that of the glass powder is no less than 30 wt% so that the adhesive force can be prevented from delerioration and sufficient coloration ability of the opaque material can be rendered.
The adhesive may be selected from polyvinyl butyryl resin, urethane resin, epoxy resin and methyl acrylate resin or a mixture thereof, and the thickness of each coating layer may range from 0.004 mm to 0.18 mm, so said coating layers will not fade under sunshine due to the use of heat-resistant ceramic color frit as material.
II
The laminated ornamental glass thus obtained may therefore be used not only as a glass with elegant and delicate coloured patterns for outwardly-facing windows or curtain walls of buildings but also as an ornamental inlaid material for outer walls of buildings. In addition, no duplicated virtual images or distorted static images can be seen on the surface of the, laminated ornamental glass in which the intermediate coating layers are of opaque materials. Said intermediate coating layers may be thickened up to about 50 mm without the occurrence of the above-mentioned virtual problems. It means that the laminated ornamental glass of the present invention is 30% safer than conventional single sheet glass with the same thickness, and the penetration resistance, high net crack, sound insulation, and heat insulation will approach 100% when its thickness is up to mm. Moreover, the adhesive may be further admixed with infrared or ultraviolet absorbents to absorb infrared rays or ultraviolet rays from outdoors, or embedded with steel wires or nets to make the glass become explosion-proof and theft-proof.
ooeo Laminated ornamental glass according to the present invention, and the prior art, will now be described in greater detail with reference to the accompanying drawings, in which: Fig. 1 is an enlarged cross-sectional view of the structure of a conventional laminated safety ornamental glass; Fig. 2 is an enlarged cross-sectional view of the structure of an embodiment of the present invention; Fig. 3 is an enlarged cross-sectional view of the structure of another embodiment of the present invention; I ill I g -P CI ii F ~-LI Fig. 4(a) is an enlarged cross-sectional view of the structure of a further embodiment of the present invention in which the glass substrate is bent rather than flat; Fig. 4(b) is an enlarged cross-sectional view of the structure of an even further embodiment of the present invention in which the glass substrate is bent rather than flat; Fig. 5(a) is a view of a pattern composed of circles employed in this invention when viewed from inside; Fig. 5(b) is a view of a pattern composed of hexagons

Conventional laminated ornamental glass, as shown in Fig. 1, is composed of an outwardly-facing trarsparent or light-colored plate glass substrate two layers of resin adhesive a layer of re'sin film or paper 3' with a glazed painting or other pattern printed or coated thereon, positioned between the two adhesive layers and an inwardly-facing transparent or dark-
I--
~p aaarr~usP~ LI III~ kr colored heat ray absorbing plate glass substrate In other words, the glazed painting or other pattern of the conventional laminated ornamental glass is simply printed or coated on an intermediate layer of a resin film or paper 3' and then the patterned layer 3' is laminated between the plate glass substrates 1' and As the laminated ornamental glass thus obtained is not transparent, cannot be seen through, it can only be used for interior partitions or as an inlaid material f?.r B inner walls of buildings, rather than being used as an inlaid material for outer walls or the glass for outwardly-facing windows or curtain walls of buildings.
In Fig. 2 to Fig. 5, however, 1 is an outwardly-facing transparent or translucent, flat or bent, plate glass substrate which is selected from sodium calcium silicates reinforced glass with or without heat treatment or sodium, potassium ion exchange reinforced glass; 2 is a conventional transparent adhesive which is selected from polyvinyl butyryl resin adhesive, polyester resin adhesive, methyl acrylate resin adhesive, urethane resin adhesive, two-component epoxy resin adhesive, one-component ultraviolet-sensitized curing adhesive, or one-component heating curing adhesive; 3, 5 and 6 are each a coating layer having an array of intercrossing stripes or net configuration composed of circles,' tetragons, or hexagons, wherein 3 is an opaque glazed painting or other pattern coating layer, 5 is a white coating layer and 6 is an oil ink coating layer which together leave crevice portions 2a without any coating betzn the opaque patterned coating layers 3, 5 and 6; 3 is directly printed or L dC sPIDllil~ YI*~~sl ar~- 1---I coated by a conventional color inkjet printer (not shown in the figures) which is connected to a computer with a pre-written design program stored therein on the inner side of the outwardlyfacing plate glass substrate 1; 5 and 6 are then in turn printed or ccated over 1 by conventional spray coating or roll printing methc I followed by engraving in an array or net figures selected from circles, tetragons, or hexagons out of the coatinig layers by a laser engraving machine (not shown in the figures) connected to the computer as above-mentioned, leaving transparent coating-fee crevice portions 2a between the opaque, patterned coating portions; and 4 is an inwardly-facing transparent, light-colored, or translucent, flat or bent plata glass substrate which may be replaced by polyester or polycarbonate resin plate depending upon the desired use and need; in addition, 7 is a transparent flexible resin film which is most preferably selected from polyethylene terephthalate (PETE).
A metallic oxide coating layer with a mirror-reflecting effect instead of aforesaid glazed painting or other pattern coating layer may be printed or coated by a reflecting film treatment such as the application of the conventional vacuum deposition method or thermal decomposition oxidation film method on the glass substrate in a thickness ranging from 400A to 1800A to render the glass substrate a heat ray reflecting glass. Said metallic oxide is an oxidation paste selected from gold, silver, platinum, copper, tin, zinc, chromium, titanium, aluminum or nickel, or an alloy thereof.
The special features of the present invention are especially understood in terms of Fig. 6 and Fig. 7. Fig. 6(a) and Fig.
