Definitions
- the present invention relates to printable and printed substrates, in particular Specialty papers, processes for making them and their uses.
- WO 97/18090 (Kimberly-Clark) describes a printable special paper which has a filmable layer arranged on a carrier material, and which is provided after printing using heat and / or Print to be filmed on a large scale. The print is then behind the filmed Layer essentially irreversibly bound and protected.
- the specialty papers described above have a number of disadvantages. So the special papers need to be fully filmed for a period of 20-60s kept at temperatures of 140 ° C to 180 ° C. Such conditions can but only with very special heating presses or with laminators of the highest price range can be set. Furthermore, there is the problem that in particular a one-sided filmable coating (and this is often preferred for cost reasons) after the filming the special papers are no longer flat or a curvature the papers already appear during filming in the laminator and the papers therefore occasionally have a tendency to get stuck in the laminator.
- the object of the invention is to specify how prints, in particular inkjet prints, are more abrasion-resistant, smudge-proof, water-resistant, brilliant, light-resistant and finally also be made more resistant in the sense of increased security against counterfeiting can.
- the substrate should also be inexpensive and using conventional machines can be manufactured.
- the invention relates to a printable substrate according to claim 1 and a method for producing such a substrate according to claim 7.
- the invention further relates to a printed substrate according to claim 10 and a method for producing such a substrate according to claim 12.
- Claims 17-19 relate to special uses of the substrates according to the invention.
- the essence of the present invention is therefore to apply to a substrate e.g. out First apply a pressure-fixing layer to paper on at least one side, and on this pressure-fixing layer an organic pigments (plastic pigments) and binders Applying filmable coating containing.
- This filmable coating is intended, after printing by feeding at least of Heat, but preferably heat and pressure, to be filmed.
- the ink penetrates into the porous filmable coating during printing, penetrates this and becomes when reaching between the carrier material and filmable Layer arranged pressure fixing layer bound on or in the fixing layer. In front in other words, part of the ink is in the filmable part Layer, and the other, usually larger part of the ink is in resp. on the pressure fixing layer bound.
- Other printing inks, such as those used in offset processes are used, and which due to their physico-chemical properties cannot penetrate into the filmable coating, remain after the printing process essentially on the surface of the filmable coating.
- the filming of the filmable layer has the effect that the print is subsequently behind or in the filmed layer more abrasion-resistant, smudge-proof, water-resistant, brilliant, and is more lightfast.
- the use of the pressure fixing layer leads to the fact that if there is residual porosity after filming or if it is microscopic If the film is torn, the print is still water-resistant because the pressure-fixing layer the ink binds under the film. The printed image appears Viewer with increased brilliance. It has also been shown that according to the invention Print images produced are much more lightfast than conventional inkjet prints. Additional and expensive laminations, such as those made with inkjet papers are superfluous. After printing essentially on the Other printing inks remaining on the surface are also removed by filming partially welded in and tied more tightly.
- Such a formulation of the filmable layer allows filming temperatures below or in the range of 100 ° C. These are conditions with cheap laminators can be easily adjusted.
- the wording allows despite the low film forming temperature is still a coating process for that Substrate for which none of the filmable layer is dry when the application is dried early filming of the coating takes place, and also the substrate before printing, do not store under special conditions such as cooling become.
- the low filming temperature also results in The advantage is that the film does not dry out as much as it does when filming Temperatures above 100 ° C is the case. So the substrates remain after filming still flat and the risk of a jam in the laminator is reduced. It shows that especially when using the above, low-melting organic pigments the use of the pressure fixing layer a pinpoint and waterproof print results.
- Another embodiment is characterized in that the pressure fixing layer cationic and absorbent, particularly preferably water-resistant is.
- the ink becomes active from the print fixing layer during printing sucked down and, since inks are usually anionic in character, precipitated from the cationic portions of the pressure fixing layer and fixed.
- the print image appears both with a high resolution and also results from the use an already waterproof pressure-fixing layer an increase in water resistance.
- Figure 1 shows a section through the layered structure of the proposed substrate 13.
- a carrier material 12 which is usually a paper, but optionally can also be a pretreated or semi-synthetic paper or a film here on one of the surfaces preferably all over with a pressure fixing layer 11 coated. Over the pressure fixing layer 11 and covering the substrate superficially there is a filmable coating 10. Depending on the application, this can Substrate 13 also made of a carrier material coated on both sides with layers 11 and 10 12 exist. It can then be printed and filmed on both sides.
- the substrate 13 should in particular be used with conventional if possible, cheap film laminators in particular.
- conventional low-cost laminators for the continuous process usually have at least a pair of counter-rotating rollers between which the laminate to be led. Either one or both are used to heat the laminate the rollers are heated, or a heating element is connected directly upstream of the rollers, which the paper or film to be laminated between penetrates the rollers warmed.
- the cheap laminators mostly only allow the setting of a single predetermined temperature, usually in the range from 120 ° C to 130 ° C, as cooling or special materials for higher temperatures for rollers and housing are necessary.
- the pressure between the rollers can be in usually not changed, and the transport speed, if any, often only be set between a few discrete values.
- conventional filmable and printable substrates according to the prior art can be found in film such laminators mostly unsatisfactorily, because higher filming temperatures and / or higher pressure are necessary, and the papers also tend after the filming to bulge.
- the three-layer laminate shown in FIG. 1 now solves this problem area by the ink after at least partial penetration into the porous filmable layer 10 is bound by a pressure fixing layer 11.
- the inks, or corresponding colors which are due to their physico-chemical properties are able to form into the filmable layer 10 penetrate, are sucked down and localized on the fixing layer 11 bound.
- the water resistance remains so high, there is no blurring of the ink on.
- Other printing inks, such as those used in offset processes, and which, due to their physico-chemical properties, cannot be filmed Coating can penetrate, can also be applied, remain but after the printing process essentially on the surface of the filmable Coating.
- carrier material 12 With regard to the type of carrier material 12 and its basis weight, there are no special requirements. Normal cellulose or cotton papers or combinations thereof with typical basis weights in the range between 80 g / m 2 and 300 g / m 2 are suitable. For prints of photographic representations it is preferred to use papers with a higher basis weight in the upper part of the specified range.
- the structure is the same for applications in the security field, but papers with additional security elements (such as watermarks, chemical security agents or paint applications containing iridescent pigments) in the weight range of 70-150 g / m 2 are preferably used here.
- the pressure fixing layer 11 is advantageously already in one in the paper production process integrated step e.g. applied with a film press.
- Layer 11 should be absorbent so that the ink from the layer 11 is active during the printing process from the filmable coating 10 is added to the pressure fixing layer 11.
- layer 11 should fix the ink and bind it waterproof.
- conventional Inks are mostly anionic in character, and fixing is easiest with achieved cationic substances to which the ink components in a precipitation be bound locally.
- absorbent components be present (e.g. silicas), a cationic binder (e.g. cationic Polyvinylamine) and preferably a binder around the dried layer to anchor the paper better.
- Other components such as plasticizers or substances to maintain lightfastness and / or UV resistance can be optional be attached.
- composition of the pressure fixing layer 11 formulated for application as an aqueous dispersion has proven to be suitable, for example: 50 g Aerosil K315 (15% dispersion, weight of the dispersion) 70 g water 26.5g Catiofast * PR 8106 (22% dispersion, weight of the dispersion) 6 g Plextol E220 (60% dispersion, weight of the dispersion) 10 g Syloid 244 (Powder weight)

It works also as a binder.
- Plextol E220 Polymer Latex GmbH & Co KG, Dormagen, DE is a 60% dispersion of a self-adhesive acrylic polymer and acts as Binder.
- Syloid 244 W.R. Grace & Co, USA is a powdered matting agent made of silica, it also reduces the viscosity of the dispersion for the Line.
- the grain size can be set to ⁇ 120 ⁇ m or smaller if required.
- the dispersion has a pH in the range of 7.5.
- the layer should be in the range of 6-10 g / m 2 , with the above-mentioned formulation ideally 8-8.5 g / m 2 are applied.
- the filmable coating 10 should have a minimum film-forming temperature which on the one hand enables filming at the lowest possible temperatures, but still an efficient drying process, i.e. reasonable drying temperatures allowed for drying the filmable coating 10.
- composition of the filmable layer 10 formulated for application as an aqueous dispersion has proven to be suitable, for example: 60 g Baystal S21C (50% dispersion, weight of the dispersion) 15 g Gohsenol GL-03 (10% solution, weight of the solution) 5 g Mowiol 28-99 (10% solution, weight of the solution) 4 g Litex PS 5020 (50% dispersion, weight of the dispersion) 4 g Plextol E 220 (60% dispersion, weight of the dispersion) 0.5 g Tinuvin 213 30 g water
- Baystal Polymer Latex GmbH & Co KG, Dormagen, DE is a 50% colloidal Dispersion of a copolymer of butadiene, styrene and acrylic acid and a low one Emulsifier. The styrene content is approximately 78%. Baystal is the essential Proportion of filmable organic polymer with a glass transition temperature in the Range from 50 ° C-60 ° C.

- the coating formulation can be applied offline or inline by means of a doctor blade application, a screen engraving roller, an air brush or in a casting process onto the substrate material 12 which has been pre-coated with the pressure-fixing layer 11.
- the layer thickness should be chosen with the above formulation in the range of 9-12 g / m 2 . If you choose thicker layers, a higher temperature must usually be selected for filming; with a thinner coating, the protective function of the layer is reduced.
- the finished non-filmed substrate can be printed using a classic printing process be, but it is particularly suitable for printing with an inkjet process.
- the ink penetrates into or through the porous filmable layer 10 and is sucked by the pressure fixing layer 11 and on this due to the cationic character of layer 11 localized fixed.
- Those types of inks, which cannot penetrate into the filmable coating remain, as they already do mentioned above, after the printing process essentially on the surface of the filmable Coating.
- the paper can be used without any further Processing by a laminator at a local lamination temperature in the area of 100 ° C.
- the local lamination temperature can be unadjustable Temperature of the laminator through the transport speed through the Laminator can be customized.
- a pressure in the range between 0.5-5 bar in a static press or a corresponding line print in a continuous laminator has proven to be sufficient and inexpensive. It is also conceivable to film it to be carried out at low temperature but very high pressure, usually must then the period of time during which the pressure is applied is also essential increase.
- Covers for the lamination process are siliconized papers, and it shows that especially not too thick papers with a thick siliconization too contribute to a good and even film adaptation.
- a so-called carrier in which the substrate to be filmed can be inserted, and whose inner surface has the desired surface structure. The substrate is inserted into the carrier for the lamination process, and after lamination, the carrier is removed from the filmed paper again.
- Such a carrier can ideally can be used several times.
- the invention is therefore particularly suitable for use in the security field such as. for the production of ID cards, passports, certificates or the like.
- the security paper can initially be made using a classic printing process such as. printed in an offset process and then individualized for the end user with a simple inkjet print and then in be filmed in a laminator.
- the offset printing ink remains essentially on the surface, but is also partially welded in during filming and fixed. It is also conceivable for outdoor applications or similar applications, where an extremely pronounced protection of the printed image is necessary, the substrate with the use of conventional foil bags in which the paper is embedded and laminated.
