Description

Detailed Description of the Invention

FIELD OF THE INVENTION The present invention relates to interior / exterior materials for automobiles, ships, aircrafts, cosmetic containers, caps, general-purpose packages, in-mold molded products, light electrical appliances, interior / exterior building materials, high-grade sliding doors, railing, kimonos, and obi. The present invention relates to a transfer foil used for decoration of various articles such as clothes, woodwork, furniture, plastic products, crafts, folk crafts, books and albums. More specifically, the present invention relates to a transfer foil having a soft feeling that can give a decoration having a soft touch feeling to these articles.

[0002]

2. Description of the Related Art Conventionally, transfer foils have been used for decoration of various articles, and there are matte transfer foils for imparting a matte gloss. The structure is generally such that at least a protective resin coating layer, a metal vapor deposition layer, and an adhesive layer are sequentially formed on the base film directly or via a release layer, and the protective resin coating layer is matted to provide a matte coating. It is in the form of a sheet (see, for example, JP-A-63-62785).

Matting agents used for matting the protective resin coating layer include, for example, silica, talc, calcium carbonate, precipitated barium sulfate, alumina, acid clay, clay, magnesium carbonate, carbon. Inorganic powders such as black, tin oxide and titanium white are used alone or in combination.

As described above, the conventional matte transfer foil uses an inorganic matting agent in its protective layer, and it has a matt effect from a visual point and a soft impression. Was satisfied with.

However, it lacks tactile softness, that is, so-called soft touch feeling. For example, the powder of the inorganic substance used as a matting agent is hard in itself, and thus the protective layer obtained by dispersing and mixing the matting agent of the inorganic substance also becomes hard, and the matting effect from the visual aspect is not achieved. Anyway, it lacked tactile softness, so-called soft touch feeling.

[0006]

SUMMARY OF THE INVENTION In the present invention, since the powder of an inorganic substance is dispersed and mixed as a delustering agent in the protective layer in the conventional matte transfer foil, the hardness of the powder of the inorganic substance itself. Has a direct effect on the surface hardness of the protective layer, the flexibility of the protective layer, and the elasticity of the protective layer, and aims to solve the problem of lacking tactile softness, so-called soft touch feeling.

That is, it is an object of the present invention to provide a transfer foil having a matt effect from the visual side after transfer and a soft touch feeling which gives a soft tactile sensation. .

[0008]

The present invention provides a transfer foil in which a decorative resin coating film layer and an adhesive layer are sequentially formed on a releasable surface of a substrate, and the average particle diameter is in the resin coating film layer. Is 2 to 2
The present invention relates to a transfer foil having a soft feeling, in which spherical organic polymer fine particles of 00 μm are dispersed and mixed.

[0009]

Functions and Examples In the transfer foil of the present invention, the average particle diameter of the resin coating layer which becomes the surface layer after the transfer is 2 to 200
Spherical organic polymer particles of μm are dispersed and mixed.

Since the spherical organic polymer fine particles have elasticity and excellent dispersibility in the matrix as compared with the inorganic powder conventionally used as a matting agent, they are dispersed in the resin coating layer. Does not deteriorate the physical properties of the coating film, gives a tactile soft touch feeling that is not possible when using conventional inorganic powder, and does not easily scratch even if rubbed with a nail, It has no change in gloss and has excellent scratch resistance. Further, the resin coating layer has excellent hiding power and coloring power, and can sufficiently follow the stress strain of the coating film.

The spherical organic polymer fine particles used in the present invention include (meth) acrylic polymers, styrene polymers, urethane polymers, acrylonitrile polymers, polyester polymers, epoxy polymers and the like. Examples of the spherical fine particles include (meth) acrylic polymers such as alkyl (meth) acrylate polymers, polyether-based urethane polymers, polyester-based urethane polymers, and polyester-ether-based urethane polymers. Fine particles of a polymer are preferable because particles having a wide range of elasticity can be obtained. Here, the spherical shape includes not only a true spherical shape but also a spherical shape slightly deviated from the true spherical shape.

As the spherical organic polymer fine particles, fine particles having an average particle diameter of 2 to 200 μm are used. When the average particle size is less than 2 μm, the unevenness on the surface of the resin coating layer is extremely small and a soft touch feeling is hardly obtained. On the other hand, large particles having an average particle diameter of more than 200 μm are not preferable because the graininess becomes too strong. Average particle size is 2 to 2
Within the range of 00 μm, it may be monodisperse or polydisperse.

Further, as the spherical organic polymer fine particles, uncolored fine particles, fine particles colored with a pigment or a dye, or a mixture of both can be used if necessary. The spherical organic polymer fine particles have a true specific gravity of 1 to 3.4.

The proportion of the vehicle and the spherical organic polymer fine particles in the decorative resin coating layer is 100 parts by weight (parts by weight,
The same applies hereinafter), the latter 5 to 100 parts, especially 5
A range of up to 70 parts is preferred. If the proportion of the spherical organic polymer fine particles is less than the above range, it is difficult to obtain a tactile soft touch feeling. On the other hand, if the proportion of the spherical organic polymer fine particles is more than the above range, the rough feeling becomes strong and the physical properties of the coating film deteriorate. If necessary, a colorant such as a dye or a pigment, a drier or the like may be mixed in the resin coating layer.

In the present invention, it is preferable that the vehicle and the spherical organic polymer fine particles have a good affinity for each other, the spherical organic polymer fine particles have a good dispersibility, and scratch resistance and the like are further improved. To be done. For example, for (meth) acrylic polymer particles, as a vehicle, polyurethane resin, acrylic resin, polyester resin, urethane-acrylic resin, epoxy-acrylate resin, polyester-acrylate resin, etc. are preferable. On the other hand, as the vehicle, urethane-acrylic resin, urethane elastomer and the like are preferable.
