Abstract

PURPOSE:To improve transfer operability, and to transfer to a substrate material with good sharpness by providing a transparent barrier on the transfer medium in combination with the substrate material, and providing a transparent adhesive layer protruding on the barrier layer, and increasing the difference of the adhesive strength of a peeling region from that of the transfer region. CONSTITUTION:A transfer material is composed of a peeling film 1 as a substrate material, a transparent peeling varnish layer 2, a first picture pattern ink layer 3, a solid concealing layer 4, a second picture pattern ink layer 5, a transparent barrier layer 6, and a partly provided transparent adhesive layer 7. The layer 2 is formed normally of acrylic resin, but the part provided with the layer 7 carries the pattern necessary from the transfer material side to the transfer medium as a transparent resin substrate material, and the unnecessary part provided with no layer 7 accurately remains on the film 1. The layer 6 does not adhere to the substrate even by a hot pressure press. When the transfer medium obtained in this manner is thermally pressure transferred to the substrate material 8, a decorative material is obtained.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a special decorative material, and more specifically, a pattern transferred to a transparent base material or sheet, as viewed from the base material or sheet side. It is different from what it looks like from the transfer material side, and the pattern on the front side is expressed as if it has disappeared or appears depending on the presence or absence of a light source from the back side. It relates to a method of manufacturing materials.

(Prior art) Decorative materials have been used in the past that are made from a transparent base material or sheet and have different designs on the front and back sides of the axe, so that when light shines from the back side, the front handle appears to disappear. Due to its design, it is used in glass windows, doors, lighting equipment, decorative materials, and daily goods, and it can be used in a wide range of applications in the future.

However, in order to form a pattern on the base film, the manufacturing method is to print the part from which the pattern is to be removed as a film-like pattern layer, then overlay the pattern or solid pattern on top of that by -C printing, and finally remove the excess. There is a method of removing the film or printing a pattern while adjusting the register in the form of fine spots, and a method of printing a pattern or a solid pattern while increasing concealment as a transfer foil, using a transfer roll with unevenness of fine spots. You can print the pattern on the base film using water-soluble ink, or print the part you want to remove as a pattern on the base film.
There is a method of printing a pattern on top of it by hand and then removing the excess part in a washing process, or printing a pattern or solid pattern, applying an adhesive layer to the entire surface, and then hardening the unnecessary parts. The method used was to cover up the area with sexual ink and prevent unnecessary parts from being transferred.

However, these methods require high printing accuracy, have poor workability, and have a high defective rate, so other methods have been investigated.

(Problems to be Solved by the Invention) The present invention attempts to solve the above-mentioned drawbacks of the prior art, and provides a decorative material that is inexpensive, easy to work with, and has an excellent design effect. This article explains how to do this.

(Specific means for solving the problem) The present invention uses a release film as a base and includes a transparent releasable varnish layer, a first pattern ink layer, a solid hiding layer, a second pattern ink layer, and a transfer target layer. H
The transparent adhesive layer side of the transfer material, in which a transparent barrier layer that is easily peelable against the surface of the substrate and a transparent adhesive layer provided partially in the form of a net or dots, is laminated in this order on a transparent substrate to be transferred. This is a method for producing a decorative material having a light-shielding property, which is characterized in that the parts are pressed together and hot-pressed, and only the partially provided transparent adhesive area is transferred to the transfer-receiving substrate side.

The configuration of the transfer material (transfer foil) used in the method of the present invention is as follows:
As shown in the figure, '4 type film 1 as a transfer base material,
Transparent release varnish layer 2, first pattern ink layer 3, solid concealing layer 4
, a second pattern ink layer 5, a transparent barrier layer 6, and a partially provided transparent adhesive layer 7. The releasable film is typically a polyester film (polyethylene terephthalate film), but may also be a polypropylene film, a polyethylene film, a polyphenylene sulfite film, a nylon film, etc. depending on the case. The transparent release varnish layer 2 is usually made of acrylic resin, but where the adhesive layer 7 is provided, the necessary pattern is transferred from the transfer material side to the transferred object side as a transparent resin base material. , adhesive layer 7IJ'r=2 Unnecessary portions that are not cut off remain on the releasable film 1 accurately. Therefore, it is necessary to improve the releasability, and the adhesion to the releasable film 1 is adjusted using additives. 1 per inch by experiment
Good results were obtained when the peel strength was 0 g or more.

However, if the peel strength is 25 (1 or more), it is too heavy and there is a risk of interlayer peeling of the adhesive layer 7, which is not preferable. The material 4 is preferably a material used in normal transfer and has a hiding property, such as an acrylic type, a chlorinated rubber type, a salt-vinyl acetate type, a urethane type, a polyester type, or the like.

Further, if the solid hiding layer 4 has a multi-layer structure consisting of a solid ink layer, a vapor deposited layer, and a solid ink layer, better hiding properties can be obtained. In this case, the vapor deposited layer is designed for the purpose of providing hiding properties. (Since the reflected brightness is not necessary, 4
A thickness of about 0.00 to 600 angstroms is sufficient. In addition, although the transparent barrier layer 6 has good adhesion with the second pattern ink layer 5, the solid concealing layer 4, and the partially provided transparent adhesive layer 7, it has poor adhesion to the transparent base material as the transfer target base material. It is necessary that the resin does not adhere even when hot-pressing is applied, and a polyester-based or urethane-based resin is desirable because it is heat resistant and has good adhesion to the second pattern ink layer 5 and the solid concealing layer 4.

The adhesive layer 7 varies depending on the transfer target substrate, but
Acrylic, urethane, salt-vinyl acetate, polyester,
Ethylene vinyl acetate-based resins, chlorinated polypropylene-based resins, etc. are suitable.

A decorative material is obtained by heat-pressure transferring the thus obtained transfer H onto a transparent transfer target substrate 8, as shown in FIG.

(Function of the invention) As shown in FIG. 1, the transparent adhesive layer 7 in the transfer material used in the method of the invention slightly protrudes from other layers, compared to the area without the adhesive layer I. Therefore, heat transfer is poor in this area, and the transferred substrate 8
This provides a more solid contact with the material. On the other hand, a transparent barrier layer 6 is present in a portion unnecessary for the pattern, and has the effect of reducing the adhesiveness to the transfer target substrate 8. This has the effect of improving the backing of unnecessary parts to constitute the transparent part of the decoration H and the contrast in peel strength between the unnecessary parts and the necessary parts.

(Effects of the Invention) In the method for producing a decorative material of the present invention, a transparent barrier layer is provided on the transfer material to be superimposed and transferred onto the transfer target H, and 92 transparent adhesive layers protrude on the barrier layer. , which has a large difference in the adhesive strength in the peeling area compared to the adhesive strength in the transfer area, has good transfer operability, can perform sharp transfer to the transfer target substrate, and has a sharp pattern that is light-shielding. It is possible to produce decorative materials with transparency and transparency.

(Example) An acrylic resin release varnish with a peel strength of 15 g/1 nch by adding polyester additives to a 25 μm thick polyester film (approximately 2 g/In (fl'y),
11 coats using a gravure printing machine, printing a wood grain pattern with acrylic hiding ink, overprinting a brown solid concealing layer, a white solid concealing layer, and a character pattern layer in order, and then Approximately 2 g/ll of polyester resin as a transparent barrier layer
1dry was coated solidly using a gravure printing method. A transfer material was prepared by printing an acrylic resin adhesive on an R sliding door with a printing machine using a printing plate with a polka dot pattern. The obtained transfer material is overlaid on a transfer substrate of a transparent Borisjilene plate and pressed with a hot glue, and then the polyester film of the transfer substrate is peeled off and the polka dot area printed with the transparent adhesive appears. The image is transferred neatly to the transparent transfer substrate, and the area where the transparent adhesive is not printed remains on the transfer substrate, and the border area is a sharp edge with no firmness. Obtained.

In the decorative material obtained in this way, the wood grain pattern is formed in a polka dot pattern on a transparent poly or sutra board, and when there is no light irradiation from the back side, the wood grain pattern is formed by the reflected light from the front side. When the wood grains developed and the light irradiated from the back side was strong, the wood grain pattern on the front surface became warmer and seemed to disappear, resulting in a decorative material with a special visual effect.
