Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a novel sublimation printing transfer foil and a method for producing the same. More specifically, the present invention relates to a sublimable textile transfer foil that can simultaneously perform coloring using a sublimable dye transfer foil and imparting metallic luster using a metal vapor-deposited transfer foil.

[Prior Art] Conventionally, for example, for transfer to kimono fabrics, a method has been adopted in which an adhesive layer is provided on the fabric in advance by textile printing, and a metallic luster is imparted thereon by heat-pressure transfer. Furthermore, coloring of fabrics using sublimable dye transfer foil has been conventionally performed. However, a sublimation printing transfer foil that can simultaneously impart color and metallic luster using one transfer foil has not yet been developed.

[Means for Solving the Problems] However, as a result of various studies, the present inventors found that 1. At least the releasable base material A, the protective resin layer B, and the metal vapor deposited layer C1.
It consists of a sublimation textile printing layer E and an emulsion adhesive layer F, of which A, B and C are laminated in the order of A/B/C, and E and F are each coated with an arbitrary pattern on the C side. Either they are printed and laminated independently, or they are separated from at least the releasable base material A, the protective resin layer B, the metal vapor deposited layer C1, the solvent-based adhesive layer D, the sublimation printing layer E, and the emulsion adhesive layer F. Of these, A, B, C and D are A.
/B/C/D are laminated in this order, and E and F are individually printed and laminated with arbitrary designs on nine sides, so that coloring and metallic luster can be added using one transfer foil. We discovered the completely new fact that it is possible to change the sublimation printing transfer foil at the same time, and completed the present invention.

That is, the present invention consists of (1) at least a releasable base material A, a protective resin F'B, a metal vapor deposited layer C5, a sublimable textile printing layer E, and an emulsion adhesive layer F, among which AS
B and C are laminated in the order of A/B/C, and E and F are laminated with an arbitrary design printed on the C side independently, or 2. At least removable base material A, protection It consists of a resin layer B, a metal vapor deposited layer C1, a solvent adhesive layer D, a sublimation textile printing WE, and an emulsion adhesive layer F, among which ASB, C and D are laminated in the order of A/B/C/D. To provide a sublimation printing transfer foil characterized in that E and F are independently printed and laminated with arbitrary designs on nine sides.

As the releasable base material A in the sublimation printing transfer foil of the present invention, any material can be used as long as it has sufficient self-retention properties, such as polyester, polyamide, polyamideimide, polyethylene, polypropylene, cellulose acetate, polycarbonate, Resins such as polyvinyl chloride and fluororesin, film or sheet materials such as cellophane, film or sheet materials of stainless steel or other metals, etc. are used as appropriate.

In particular, it is preferable to use a film-like material of the above-mentioned resins with a thickness of about 6 to 50 microns as the releasable base material, since it is possible to continuously mass-produce a sublimation printing transfer foil without wrinkles or cracks. Note that the releasable base material is transfer N (protective resin layer B,
Metal vapor deposition layer C1 solvent-based adhesive FiD, sublimation textile printing F
Composite N consisting of EE and emulsion adhesive PIF
), the surface of the support may be treated with silicone resin, wax, surfactant, metal oxide, fluororesin, etc.

Since the metal vapor-deposited MC itself of the sublimation print transfer foil of the present invention has low mechanical strength and is easily damaged by friction, a protective resin F'B is provided in advance on the lower surface of the metal vapor-deposited layer. The thickness of the protective resin layer is not particularly limited, but is usually appropriately selected from a range of about 0.5 to 2 .mu.m.

The protective resin layer B in the sublimation printing transfer foil of the present invention includes thermoplastic resin, thermosetting resin, electron beam curable resin,
Any UV-curable resin can be used, such as acrylic resin, vinyl chloride-vinyl acetate copolymer, polyvinyl butyral, polycarbonate, nitrocellulose, cellulose acetate, urethane resin, urea resin, melamine resin, urea-based resin, etc. Preferably used are melamine resins, epoxy resins, alkyd resins, aminoalkyd resins, rosin-modified maleic acid resins, and the like alone or in blends.

The protective resin layer can be formed using a roll coating method, a gravure coating method, or a gravure coating method using an organic solvent solution, aqueous solution, etc. of the resin.
This is carried out by applying by a conventional coating method such as a reverse coating method or a spray coating method, and drying (curing in the case of a thermosetting resin, an electron beam curable resin, an ultraviolet curable resin, etc.).

In this specification, vapor deposition means forming a thin film of metal by a normal thin film forming method of metal (including alloys, the same applies hereinafter) such as vacuum vapor deposition, sputtering, and ion blating, The metal vapor deposited layer C includes all of the metal thin films formed by these metal thin film forming methods.

In the present invention, the metal vapor deposited layer C is usually selected from a range of 5 to 100 mμ, preferably from a range of 30 to 80 mμ. If the thickness of the metal vapor deposited layer is less than 5 mμ, the light reflectivity of the metal vapor deposited layer is poor, and sufficient metal glitter cannot be obtained, which is not preferable. On the other hand, even if the thickness exceeds 100 mμ, the light reflectivity of the metal vapor deposited layer does not change, so this is unfavorable from an economical point of view, regardless of metal glitter.

Examples of metals used to form the metal vapor deposition layer C include aluminum, copper, gold, silver, platinum, chromium, indium, zinc, tin, nickel, and titanium.
Aluminum is usually preferably used from the viewpoint of light reflectance and economy.

In the sublimable textile transfer foil of the present invention, the sublimable textile printing F
The thickness of the EB is usually selected from the range of 0.5 to 3μ, more preferably from the range of 0.8 to 2μ.

If the sublimation printing layer has a thickness of 0.5 μm without grooves, it is not possible to contain the sublimation dye in an amount necessary and sufficient for printing, and therefore a sufficiently colored sublimation printing transfer foil cannot be obtained, which is not preferable. On the other hand, if it exceeds 3μ, it becomes difficult to print fine patterns, which is not preferable.

The sublimation textile printing ink for forming the sublimation textile printing layer E should have excellent adhesion to the metal vapor deposited layer C, and be as non-adhesive as possible to the fabric to be transferred. At the same time, it must contain a sublimable dye in a state that can be sublimed by heating.

Sublimation textile printing inks that do not meet these requirements include, for example, styrene-maleic acid resin-based, maleic acid resin-based,
A sublimable textile printing ink prepared by mixing a sublimable dye with a resin binder such as a cellulose resin is preferably used.

The sublimation textile printing WE is formed by printing the sublimation textile printing ink using a conventional printing method such as a gravure printing method or a letterpress printing method.

Examples of sublimable dyes used in combination with the sublimable textile printing ink include disperse dyes such as monoazo, disazo, atraquinone derivatives, nitrostyryl, methinearoylene benzimidazole, quinonatutalone, aminonaphthylimide, naphthoquinoneimine, and coumarin derivatives. It will be done.

In the sublimation print transfer foil of the present invention, the thickness of the emulsion adhesive layer F is usually selected from the range of 2 to 10 microns, more preferably from the range of 3 to 5 microns. Emulsion adhesive Ji
If the thickness of F is less than 2 μm, sufficient transfer strength cannot be obtained for the material to be transferred, which is not preferable. On the other hand, if it exceeds lOμ, the metal vapor deposited layer will be deformed and whitened due to fluidization of the adhesive layer during transfer, which is undesirable, as the metal luster will deteriorate.

The emulsion adhesive for forming such an emulsion adhesive, #IMF, is required to have excellent adhesion to the metal vapor deposited layer C and the material to be transferred. As adhesives satisfying such requirements, for example, emulsion adhesives such as acrylic, vinyl acetate, vinyl chloride, polyethylene, and styrene-butadiene, either alone or in a blend, are preferably used.

Formation of the emulsion adhesive layer F is performed by printing an aqueous solution of an emulsion adhesive for forming the emulsion adhesive layer F using a conventional printing method such as a gravure printing method, a letterpress printing method, or a screen printing method. .

Further, in order to improve the adhesion between the metal vapor deposited MC and the emulsion adhesive PIF, a solvent adhesive HD may be provided on the surface of the metal vapor deposited layer C. Such solvent-based adhesive FilD
The solvent-based adhesive FilD for forming the above-mentioned material has excellent adhesion to the metal vapor deposited layer C and the emulsion adhesive layer F, and is as non-adhesive as possible to the fabric to be transferred. something is required. Adhesives that meet these requirements include ethylene-vinyl acetate,
Chlorinated polypropylene type, vinyl chloride-vinyl acetate type,
Solvent-based adhesives such as acrylic adhesives and acrylic-vinyl chloride-vinyl acetate adhesives are preferably used alone or in blends.

The formation of the solvent-based adhesive layer is carried out by applying an organic solvent solution of the solvent-based adhesive to form the solvent-based adhesive layer using a conventional method such as a roll coating method, a gravure coating method, a reverse coating method, a spray coating method, etc. This is done by applying by a coating method and drying. The thickness of the solvent-based adhesive F'D is usually selected from the range of 0.5 to 3μ, more preferably from the range of 0.8 to 2μ.

If the thickness of the solvent-based adhesive HD is less than 0.5 μm, sufficient transfer strength cannot be obtained, which is not preferable. On the other hand, if it exceeds 3μ, the metal vapor deposited layer deforms and whitens as the adhesive layer fluidizes during transfer, resulting in a decrease in metal optical stability and staining of the non-transfer material, which is undesirable.

Next, the present invention will be explained with reference to Examples.

[Effects of the invention] When the sublimation printing transfer foils obtained in Examples 1.2.3 and 4 were transferred to acrylic and nylon fabrics, there was a metal glitter layer on the surface of the fabrics due to the metal vapor deposition layer.

The resulting fabric was prepared using a conventional method for transferring onto kimono fabrics, in which an adhesive layer was applied to the fabric in advance, and then an adhesive layer was applied on top of the adhesive layer by heat-pressure transfer to impart metallic luster to the fabric. It looked like gold-decorated fabric processed using the traditional method, which consisted of a four-step process using sublimation dye transfer foil.
