Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cosmetic material rich in natural feeling and having a painted feeling.

[Conventional technology]

Conventionally, in the production of cosmetic materials, there is a method that uses a matte ink and a glossy ink together to give a three-dimensional feeling and a feeling close to natural products such as natural wood, but products obtained by that method are Still lacks three-dimensional depth. Also,
As another method for obtaining three-dimensional depth, there is a method of forming a transparent synthetic resin layer on a pattern printed on a base material and embossing, and according to this method, a three-dimensional effect can be obtained temporarily, Gloss is determined by embossing, and it is difficult to obtain a design feeling as desired.

[Problems to be solved by the invention]

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a decorative material having a material feeling and a three-dimensional feeling close to those of a natural product such as a natural tree and a painted feeling.

[Means for Solving the Problems] The present invention for achieving the object described above is characterized in that a synthetic resin layer, a concealed solid printing layer, a pattern printing layer are sequentially laminated and embossed on a base material, and then the transparency is further improved. A decorative material comprising a synthetic resin layer having the following and a gloss adjusting layer sequentially laminated.

The cosmetic material of the present invention will be described with reference to the drawings. A synthetic resin layer 2, a concealed solid print layer 3, and a picture print layer 4 are sequentially laminated on a base material 1, embossed 5, and then a synthetic resin having transparency. The layer 6 and the gloss adjusting layer 7 are sequentially laminated.

When the embossing is the fine unevenness of the natural wood bark, fiber shape and hairline shape, and when used as a wood grain decorative material, the cosmetic material has a fibrous, shining, and deep feeling close to that of natural wood and has a painted feeling. was gotten. When a glittering ink is used for the pattern print layer, the decorative material becomes closer to natural wood.

Various papers can be used as the base material in the decorative material of the present invention, for example, thin paper, bleached or unbleached kraft paper, high-quality paper, inter-sheet reinforced paper (latex-impregnated paper), mixed paper mixed with synthetic resin, There are titanium paper, linter paper, paperboard, gypsum board paper and the like. Also, plastic films can be used, for example, polyethylene, polypropylene, polyvinyl chloride, polyvinyl alcohol, polyethylene terephthalate, polycarbonate, nylon, polystyrene, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, ionomer Etc. There is a plastic film. In addition, wood base material such as wood, plywood, particle board, gypsum board, gypsum base material such as gypsum slag board, fiber cement board such as pulp cement board, asbestos cement, wood chip cement board, GRC and concrete, iron, aluminum, A metal foil or sheet such as copper can also be used. Of course, a substrate in which the above various materials are composited can also be used.

The synthetic resin layer provided on the substrate is made of polyethylene, polypropylene, an ethylene-vinyl acetate copolymer, a polyolefin resin such as an ionomer, a thermoplastic resin other than the above such as a saturated polyester or polyvinyl chloride, and an unsaturated polyester resin. What is necessary is just to use what was chosen from thermosetting resins, such as polyurethane resin and polyurethane resin.

In order to form a layer of a synthetic resin, a coating method such as extrusion, T-die, roll coat, gravure coat, or the like is selected and applied according to the physical properties of the synthetic resin to be used.
The synthetic resin layer needs to have a thickness of 5 μm or more, and preferably 20 μm or more, in order to reach the purpose of embossing the resin layer. The effect is greater the thicker, but 5mm
If the amount exceeds the above range, no further improvement in the effect can be expected, and the necessary amount of the material is undesirably increased. When a polyolefin resin having poor adhesiveness is used as the synthetic resin layer, it is preferable to employ an extrusion coating method, and it is preferable to coat an anchoring agent such as alkyl titanate or polyethyleneimine before coating. Similarly, a treatment for improving the adhesiveness may be performed on the synthetic resin layer. For example, when a synthetic resin layer is formed of a polyolefin resin, it is desirable that the “wetting index” of the surface of the synthetic resin layer be 38 dyne / cm ² or more by corona discharge treatment, thereby improving the adhesion of the printing ink. .

The decorative material of the present invention is generally manufactured by sequentially laminating each layer on a base material. However, the base material and a concealed solid printing layer, a picture printing A layer obtained by sequentially laminating the layers may be laminated simultaneously with the formation of the synthetic resin layer, or a method of laminating the synthetic resin on one of the layers and then crimping the both may be adopted. It is. When the substrate is a flexible sheet, gravure printing is advantageous, but other general printing methods can also be used. In addition, when the substrate is in a plate shape, it is customary to apply silk screen printing or gravure offset printing, but other printing methods may be used.

As the ink or coating composition for providing concealed solid printing and picture printing, a composition obtained by kneading a vehicle with a coloring agent, a plasticizer, a stabilizer, other additives, a solvent or a diluent, which is a pigment or dye, is used. Materials suitable as vehicles include ethyl cellulose, ethyl hydroxyethyl cellulose, cellulose acetate propionate, cellulose derivatives such as cellulose acetate, polystyrene, styrene resins and styrene copolymer resins such as poly α-methylstyrene, polyethyl methacrylate, polyethyl methacrylate, and the like. Acrylic or methacrylic acid ester homo- or copolymer resin such as ethyl acrylate and polybutyl acrylate, rosin, rosin-modified maleic resin, rosin-modified phenol resin, rosin ester resin such as polymerized rosin, polyvinyl acetate, cumarone resin , Vinyl toluene resin, polyvinyl chloride, polyester, polyurethane, butyral resin and the like. Two or more of these may be used in combination. For solid printing, a material mainly composed of an inorganic pigment such as titanium dioxide having a high shielding property is used, and for pattern printing, an appropriate coloring agent is used.

Embossing is often used to represent a wood channel groove, to reproduce the gloss of a painted plate, or to combine them. When expressing the feeling of fiber of a tree, it is preferable to use a hairline-shaped emboss along the grain direction. In order to express the fiber feeling of natural wood with the hairline-shaped emboss, it is preferable that the pitch of the hairline be 300 μm or less. Hairline-shaped embossing and embossing such as conduit grooves may coexist, for example, one that expresses the feeling of "building", one that is close to a mirror surface for gloss, and one that erases gloss This is suitable when a wood pattern is printed. If you want to express the feel of the skin, the one that imitates the crest that is the unevenness of the surface of the skin, the satin finish, and sometimes the one that is close to the mirror surface is suitable. When expressing irregularities or cracks, or polished stones, mirror surfaces are suitable. In the case of the cloth, the texture of the plain weave, the oblique weave or the satin weave or the combination of these cloths is suitable.

As the transparent synthetic resin layer, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyolefin resins such as ionomers, other thermoplastic resins such as saturated polyester and polyvinyl chloride, unsaturated polyester resins and polyurethane resins and the like A material selected from thermosetting resins may be used.

In addition, ultraviolet curable resins and electron beam curable resins can also be used.

The gloss adjusting layer protects the surface of the decorative material and gives a desirable gloss to the surface of the decorative paper. The gloss adjusting layer can be formed by appropriately applying a paint using a vehicle. As a vehicle, a resin such as polyurethane, acrylic resin, amino resin, nitrocellulose, alkyd resin, polyester, polyvinyl butyral, melamine resin, cellulose acetate, polyvinyl chloride, polyvinyl acetate, polystyrene, polyvinyl alcohol, etc. is used alone or in combination. can do. Usually, an appropriate amount of a matting agent is dispersed in a coating material for forming a gloss adjusting layer to give a desired matting degree. However, a gloss type paint containing no matting agent at all may be used. Matting agents that can be used include mica, silica, alumina, calcium carbonate, diatomaceous earth, silica sand, and inorganic hollow bodies such as shirasu balloons.

In order to form the gloss adjusting layer, a method such as a gravure coat, a roll coat, an air knife coat, a spray coat, and a flow code may be used.When forming in a pattern, the same as when forming a pattern print layer is used. The printing method may be used. The gloss adjustment layer is composed of two paints with different gloss levels.
They can be formed in combination.

In this case, in addition to providing a mat layer on the mat layer,
A matte layer may be provided on the matte layer, a matte layer and a matte layer may be provided separately on the same surface, or one of the matte layer and the matte layer may be provided. May be solid and the other may be provided in a pattern. When the gloss adjustment layer is provided in a pattern synchronized with the pattern below, the visual three-dimensional effect is increased.

If desired, a glittering colored layer is provided on the concealed solid printing layer or the picture printing layer. It gives the shine of wood, the luster of the skin,
The brilliance of the stone or the luster of the cloth is well reproduced.

The following is an example of a pigment forming the glittering colored layer. (A) What is called pearl pigments, specifically, crushed inner parts of shells and pearls, mica,
Mica fine particles baked with TiO ₂ or iron oxide,
(B) Metal powder, specifically, fine particles of preferably 1 to 120 μm of copper, aluminum, brass, bronze, gold, silver, etc., (c) Fragments of a deposited plastic film, for example, polyethylene terephthalate film Such a metal, usually aluminum, is vapor-deposited and pulverized (silver powder), and is vapor-deposited and then subjected to transparent yellow painting and pulverized (golden powder). These brilliant pigments are selected according to the luster, shine, and shine of the object to be reproduced, and two or more of them can be used in combination as needed.
