This doubling embossed film had excellent V-cutting properties and was also superior in design due to its delicate woodgrain printing and the effect of woodgrain grooves on the surface, and was backed by long-established technology. However, doubling embossed film is also inferior to decorative laminates using thermosetting resins such as polyester decorative laminates, melamine decorative laminates, and DAP decorative laminates in terms of surface scratch resistance, heat resistance, and stain resistance. was.

の問題を解決した。次にこの内容を説明する。 Especially regarding scratch resistance,
Doubling embossed film is attached to plywood or particle board, and during manufacturing processes such as cutting, V-cutting, and assembly, scratches, cracks, and changes in gloss may occur on the surface.
A coating was applied to protect the surface. In recent years, various measures have been taken in the industry to solve these problems. Among these, a decorative film was developed in which a colored printed vinyl chloride sheet was coated with an ultraviolet curable paint. Because the surface of the film has a cured resin coating instead of the conventional thermoplastic film, the scratch resistance mentioned above can be significantly overcome. However, in this case as well, the coating film of UV-curable paint must be at least 15% to have scratch resistance on the printed surface.
g/m 2 or more is required, and it is impossible to increase the coating amount to a large extent in order to obtain V-cut suitability, and strict coating amount control is required to achieve both. Next, when an ultraviolet curable paint is directly applied to the surface of the printing ink, the curing speed of the ultraviolet curable paint differs depending on the hue of the ink, which is a drawback. The darker the color, which is closer to black, the slower the curing process, while the more transparent or low density the color, the faster the curing process. For this reason, when applying an ultraviolet curable paint directly to the printed pattern surface, it is necessary to change the ultraviolet irradiation conditions depending on the hue, and the curing conditions must be adjusted to the maximum density. For this reason, the work becomes complicated by determining the irradiation conditions for each printed pattern, and if the management is insufficient, the dark colored areas will be insufficiently cured, the physical properties of those areas will be extremely poor, and the curing speed will be slow. There were problems such as uneven gloss due to the difference. In the present invention, the above two problems were considered and these problems were solved by applying a specific amount of ultraviolet curable paint onto a transparent thermoplastic film and then doubling it onto a colored printing film. Next, this content will be explained.

ニルに比べ表面硬度や耐スクラツチ性に優れるが
可撓性に乏しく、伸びが少ないためＶカツトのよ
うなフイルムが局部的に大きく伸ばされ、折り曲
げられる場合には亀裂や白化が生じ易い。 In general, UV-curable paints have superior surface hardness and scratch resistance compared to thermoplastic vinyl chloride, but they are less flexible and have less elongation, so they can be used when a film such as a V-cut is locally stretched and bent. is prone to cracking and whitening.
一般にＶカツトに使用される塩化ビニルフイル

ある。 This is because the elongation rate of vinyl chloride film generally used for V-cuts is 50 to 200% at room temperature, while the elongation rate of ultraviolet curable paints is as low as 1 to 30%.

フ１に示す。 To solve this problem, we made two layers of UV-curable paint and vinyl chloride film and tested them with various thicknesses. As a result, we found that the coating thickness of UV-curable paint was 20 times the thickness of transparent vinyl chloride film. % or less, it was found that the V-cut could sufficiently withstand the elongation and no cracking or whitening would occur. Graph 1 shows a summary of the test results.

る。 Thickness of UV-curable paint film / Thickness of vinyl chloride film x 100 As can be seen from this table, if the film thickness of UV-curable paint is less than about 20% of the thickness of vinyl chloride film, the elongation rate will be has V-cut suitability of over 50%. Next, regarding scratch resistance, if UV-curable paint is applied directly to a printed vinyl chloride sheet as in the past, if this coating layer is scratched, the printed pattern will be scratched and the product value will be significantly reduced. Drop it. For this reason, UV-curable coatings are made thicker than necessary to ensure safety, and as a result, V
It was making it difficult to balance it with Katsuto. As explained above, in order to ensure scratch resistance, the minimum amount of UV-curable paint is applied to maintain V-cut properties, and even if the UV-curable paint layer is scratched, the transparent vinyl chloride film will remain intact. Since it is coated over the printed pattern, it does not cause fatal defects such as scratches on the printed pattern. As described above, by applying ultraviolet curable paint on a thermoplastic transparent film to a coating thickness of 20% of the thickness of the thermoplastic film, it is possible to achieve both scratch resistance and V-cut performance, and to apply the UV-curable paint directly onto a conventional printed film. When a UV-curable coating film is provided, it eliminates variations in coating performance and uneven luster caused by the curing speed depending on the hue and concentration of the ink, and if the UV-curable coating film is scratched, it will directly damage the printed pattern. The product's fatal flaws were also resolved. Next, the content stated in claim 2 will be explained.
When applying an ultraviolet curable paint, the following three points can be improved by using a transparent plastic film containing a mold release agent. UV curable paints have oxygen inhibiting properties and can be cured faster by covering them with a transparent film and irradiating them with UV rays. The curing speed is increased, the irradiation time is shortened, and since the coating surface is not directly irradiated, the heat generated from the high-pressure mercury lamp heats the substrate, causing thermal expansion and contraction, which can solve the problem of curling, flaring, etc.
A stable glossy surface can be obtained by controlling the coating surface to the surface of the plastic surface it covers. These are the three points above. In addition, when doubling embossing is performed without peeling off this transparent film that has mold releasability after the UV-curable paint has hardened, this transparent film serves as a protective film and eliminates any scratches that occur during cabinet processing. It has the advantage that it can be stored without getting dirty until it is used.

る。 The above vinyl chloride film is polyvinyl chloride,
It is mainly composed of plasticizers, stabilizers, coloring pigments, and fillers. These films include those with patterns such as wood grain patterns and marble patterns printed by gravure printing, and those with plain colors (without printed patterns).
It is broadly divided into Next, the transparent thermoplastic film 2 is a transparent or translucent sheet obtained by removing the colorant from the colored thermoplastic sheet described in 1, and the resin content is basically the same as the film 1. Next, the ultraviolet curable paint No. 3 will be described. Generally, UV-curable paints consist of a UV-curable resin as a base polymer and a photoinitiator. The base polymer of this ultraviolet curable resin is typified by acrylic resins such as polyether acrylate, urethane polyester acrylate, and epoxy acrylate, and these polymers, oligomers, and monomers are used by appropriately mixing them. The photoinitiator is usually called a sensitizer and includes benzoin ethers such as benzoin methyl ether, benzoin ethyl ether, benzoin isobutyl ether, benzoin, benzophenone, etc.
