Abstract

PURPOSE:To provide rainbow colors and enhance production efficiency, by a method wherein a vapor-deposited metallic layer is provided on a base film, force cracks are generated in the layer by tensioning it momentarily under heating conditions, and the cracked lyaer is used as a diffraction grating. CONSTITUTION:After providing an easily releasable layer 2 on a base 1, a pattern layer 3 in a desired number of colors is provided thereon, then a protective layer 4 is provided thereon if required, and the vapor-deposited metallic layer 5 is heatedto a temperatures nnot lower than a fixed temperature under a fixed tension, whereby cracks 6 orthogonal to the vapor direction of the tension and parallel to the printing surface are generated in the layer 5 due to differences in expansion property between the ink compositions. Then, an adhesive anchor layer 7 is provided if required, and an adhesive layer 8 is laminated thereon to complete the transfer foil. The releasable layer 2 is formed from an acrilyc resin, a chlorinated rubber resin or the like.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method d1 for producing a transfer foil for metal vapor-deposited hot stamping that uses light diffraction to change the iris color by one color, and the product is It is used to add designs such as +11 to the surfaces of light electrical equipment, boxed goods, accessories, toys, cosmetic containers, and other items.

(Prior art) Conventional transfer foils with glitter properties that include vapor-deposited metal layers include treatments such as hairline processing on the base film itself, matte printing on the printed surface of the base film, and pigments used in the pattern layer. These include those that are made into metal powder, or those that coat the pattern layer with a metallic luster colored with transparent ink, and all of these include coating layers other than the metal vapor-deposited layer with various T-layers. This gives it a metallic feel and design.
Not only was the culm used to produce it fertile, but there was a limit to the effect it could provide.

[Problem that the invention seeks to solve]

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to efficiently provide a transfer foil for use in metal vapor deposition stamps that shines in an unprecedented iridescent color and is inexpensive to use.

(Means for Solving the Problem) The manufacturing method of the iris-colored metal Fj'I vapor transfer adhesive of the present invention involves applying heat and tension before transferring the metal vapor deposited layer. The diffraction grating is formed by tightening minute cracks in the metal deposited layer using the expansion and contraction differences that occur between the layers that make up the diffraction grating.This explanation is shown in Figure 1. As shown, it is easy to strip the base (A (1)),

Metals are vapor-deposited on the surface through metal vaporization.
+M (5) is applied (), and then heat is applied to this transfer R at a temperature of several tens of degrees under constant tension. Eventually, cracks (6) as shown in Figure 2 will appear in each layer. Due to the difference in the expansion and contraction rate of the ink composition, tension is generated in the metal vapor layer (5) in a direction perpendicular to the vector direction of the tension and parallel to the plane. Next, if necessary; further 184 layers (F3) via 'C+e shield ijnhar@(7)
are sequentially laminated to complete the transfer foil.

This heating process is shown in Figure 3.

The pattern layer (3) includes chlorinated rubber resins, acrylic resins, vinyl chloride-vinyl acetate J (polymerized resins, cellulose resins, etc.). The first layer (4) may be a thermosetting urethane resin, a melamine-cured heliacrylic resin, a heat-resistant acrylic resin, a hill[)-su-based resin, an alkyd resin, or a 'dB combination of these resins, etc., and an adhesive anchor layer 7)
As for the adhesive layer (8), acrylic resin, chlorinated polypropylene [1-pyrene resin, chlorinated rubber, etc.] Based on the thickness of the metal vapor-deposited layer (5), approximately 200 people are required, taking into account the QI of the design as a 1.L metal vapor-deposited foil, etc. + bundle.

Although it is affected by the P2 value of the 1 film, the number does not change much in the range (IS) to 38 fl, which is normally used as a transfer foil for hot stamping. When the 1+4 film actually used as a transfer foil is a polyester film < 25 II) and the resin system of the ink used for printing is set to 6 above, the printing machine takes into account the softening point of the resin. The heat generated is from room temperature to 250°C,

The base film is then laminated in the order of the metal vapor-deposited layer (5) or the adhesive 1iW (fl) by applying a tensicon with a constant tension of 1 or more under hot air at a constant temperature of 1. :Due to the difference in the expansion and contraction rate of each printed layer, stress is applied to each printed layer and the metal vapor deposited layer sandwiched between these printed layers, and countless Wi A thin crack appears in the tension level of this l film in a direction parallel to the printing surface in the middle.
The transfer foil for the vapor-deposited small stamp is placed on the first vaporized layer of the metal lamp. However, these fine cracks cause a diffraction grating phenomenon.What kind of transfer foil for metal vapor deposition hot stamping produces a very beautiful iris color that varies depending on the color of the ftJ?

(Actual/It! 1 example) Example 1 An acrylic resin-based orchid-shaped layer and a pattern layer, and a cellulose resin-based protective A layer were laminated on a polyester film lXn fabric of 117 x 2 h//. A vaporized layer of I00Δ was installed under a tension of -1,11(')g/CIl+15
When dry heating was carried out at 0°C for 1°C, minute cracks, which were almost invisible to the naked eye, were generated. Then, a chlorinated boria 11 pyrene resin adhesive layer was applied (after 1.
The transfer is 1f1k, which is a very beautiful vapor-deposited hot stamp foil that shines in one color, but depending on the viewing angle, it shines in various colors such as yellow, red, and purple.
