Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a patterned decorative material having a deep printed pattern and a method for producing the same.

[Conventional technology]

Conventionally, there are a wide variety of pattern materials using printing ink, such as interior materials and exterior materials for buildings, and printed materials for advertising.

Some of these patterned materials are made by simply applying printing ink, but usually they are made by forming a clear coating film on top of the printing ink, as seen in printed steel plates, printed plywood, etc. I often do that. For example, in the case of a printed steel plate with a wood grain pattern, a clear coating is applied after the wood grain pattern is printed. However, in the case of a printed steel plate with a wood grain pattern, it gives a flat feeling to the viewer, so even if the desired wood grain pattern closely resembles that of natural wood, it is not possible to express the beauty and three-dimensional effect of the surface.

For this reason, various efforts have been made. One of them is embossed steel plate, which is made by applying clear paint on top of printing ink.
After baking to obtain a dry fi coating, embossing is performed to create unevenness, giving it a three-dimensional effect. In addition, by using a solvent contained in the printing agent that has a slower evaporation rate than the solvent contained in the top coat, only the top coat is dried first, thereby obtaining a product with a difference in gloss as a whole. 52-41653), a curing agent that reacts with the top coat is contained in a printing agent using butyral resin, and by baking and drying the top coat first, a product with a difference in gloss as a whole is obtained. Method (Unexamined Japanese Patent Publication No. 52-41
652), etc., which utilize the difference in curing speed between the printing agent and the top coat are known.

However, the above-mentioned method of applying an embossing roll to form an uneven pattern requires a new embossing process, which increases the cost, and the sharp edges of the embossed uneven parts make the coating thinner at the edges. The problem is that the long-term corrosion protection at the edges is poor. In addition, in methods that utilize the difference in curing speed between the printing agent and the topcoat, if a solvent with a faster evaporation rate is used in the topcoat than in the printing agent, mixing will occur between the solvents in the printing agent and the topcoat. There is a problem in that a sufficient difference in gloss cannot be obtained using normal baking methods. Furthermore, in a method in which the printing agent contains a curing agent that reacts with the top coat, it is necessary to limit the printing agent to butyral resin.

[Problem to be solved by the invention]

Therefore, an object of the present invention is to solve the above-mentioned problems, and to obtain a printed pattern that gives a deep and moist feeling, and to maintain the printed pattern for a long period of time without causing any cracking, peeling, or discoloration of the coating layer. To provide a patterned decorative material that maintains the depth of the pattern.

Furthermore, another object of the present invention is to propose a method for manufacturing a patterned decorative material, which can produce the patterned decorative material as described above in an extremely simple process.

[Means to solve the problem]

The present invention is the following patterned decorative material and method for producing the same.

A patterned decorative material formed from a clear paint containing 15 to 60 parts by weight of polymeric elastomer particles based on 100 parts by weight of a coating film-forming resin.

(2) Print a pattern on the surface of the base material using ink, and apply 15 to 60 parts of polymer elastomer particles with a particle diameter of 10 to 100 μm to 100 parts by weight of the coating film-forming resin on the formed printed layer. A method for producing a patterned decorative material, which comprises applying a clear paint containing parts by weight.

The patterned decorative material of the present invention consists of a base material, a printed layer in which an arbitrary pattern is printed with ink on the base material, and a coating layer in which a specific clear paint is applied on the printed layer.

The base material used in the present invention may be any material as long as it can withstand the curing conditions of the paint, and its material, shape, etc. are not particularly limited. Such base materials include, for example, wood,
Wooden base materials such as plywood and particle board; gypsum board,
Gypsum base materials such as gypsum slag board; fiber cement base materials such as pulp cement material, asbestos cement material, wood chip cement material; GRC and concrete base materials; metal base materials such as iron, aluminum, copper, stainless steel, titanium, zinc, etc. ; paper base material; stone base material; glass base material; plastic base material; tile base material; and composite materials of each of the above base materials.

In the present invention, the ink used to print any pattern on the base material may be any printing ink such as letterpress ink, flat plate ink, flexo ink, screen ink, gravure ink, etc. You can select the ink that is suitable for the base material. The pattern printed with the ink on the substrate is not limited, and any pattern, design, etc. can be printed.

In the present invention, in order to give depth and a moist feel to the printed layer printed using ink on the base material, a clear paint containing polymer elastomer particles is applied on the printed layer to form a coating layer. form.

The above clear paint is in the form of a coating film or contains resin and polymer elastomer particles, and is in the form of a coating film containing 100% of resin.
The coating material contains 15 to 60 parts by weight, preferably 20 to 50 parts by weight of each polymer elastomer particle.

The above-mentioned coating film-forming resin is a resin that forms a coating film by coating and drying, and there are no particular restrictions on such coating film-forming resins. An appropriate one can be selected from among them depending on the purpose of the patterned decorative material, the type of substrate, the type of ink, etc. Specifically, as such a coating film type or resin, for example, polyurethane resin, acrylic resin, polyester resin, fluororesin, epoxy resin, etc. can be used.

The polymer elastomer particles are particles of a polymer compound that has elasticity at around room temperature, and examples of such polymer elastomer particles include resins such as polyurethane resins and acrylic acid resins; modified products of these resins; Examples include blends based on these ingredients.

The polymer elastomer particles have a particle size of 10 to 100 μm.
, preferably 10 to 80 μm. If the particle size is less than 10 μm or larger than 100 μm, a moist feel cannot be provided, which is undesirable.

The above-mentioned polymeric elastomer particles are described, for example, in U.S. Pat.
It can be produced by the method described in Japanese Patent Publication No. 527729, Japanese Patent Publication No. 51-12051, etc., but commercially available products can also be used. Commercially available products include, for example, Lovecolor (trade name, manufactured by Dainichise Chemical Industry Co., Ltd.).
Colorless clear of acrylic resin elastomer), [Ia
Examples include transparent Decosilk (trade name, polyurethane resin elastomer) manufactured by Tikon.

In the clear paint used in the present invention, the film-forming resin and the polymer elastomer particles are in the form of a coating or in an amount of 15 to 6 polymer elastomer particles per 100 parts by weight of the resin.
It is blended in a proportion of 0 parts by weight, preferably 20 to 50 parts by weight. If the proportion of the polymer elastomer particles exceeds 60 parts by weight, the original performance of the resin may not be utilized and adhesion to the material may deteriorate. Further, if the amount is less than 15 parts by weight, the depth of the pattern and the unevenness cannot be obtained.

The clear paint used in the present invention is in the form of a film or is prepared by mixing resin and polymer elastomer particles with an appropriate solvent to give an appropriate viscosity during painting. Additives such as metal powder, a hardening agent, and small amounts of pigments and dyes may be added as necessary to the extent that the object of the present invention is not impaired.

The clear paint used in the present invention can be produced by mixing the above-mentioned coating film-form or resin, polymeric elastomer particles, solvent, and optionally added additives in the above-mentioned proportions.

Commercially available clear paints can be used, such as Bellsoft Oni 1000 Clear (trade name, acrylic resin paint) manufactured by NOF Corporation, Nippon Oil & Fats Co., Ltd.
Bellsoft NQ5000 (trade name, polyurethane resin paint) manufactured by Ohashi Chemical Co., Ltd., Ravi (S) Clear (trade name, polyurethane resin paint) manufactured by Ohashi Chemical Co., Ltd., Velpex (product name, manufactured by Fujikura Kaoru Co., Ltd.) Transparent paints such as Mankiewicz's Nextel (trade name, polyurethane resin paint), and Cashew Co., Ltd.'s Tuftex Suede (trade name, polyurethane resin paint) are used. You can also use

Although there is no particular restriction on the thickness of the coating layer formed from the above-mentioned clear paint, sufficient depth can be given to the pattern by generally making the coating thickness 15 to 40 microns thick.

The patterned decorative material of the present invention can be produced by the following method.

First, an arbitrary pattern is printed on the surface of the base material using l or more types of inks, thereby forming a printed layer on the surface of the base material.

To print a desired pattern using the ink, any method such as gravure printing, gravure offset printing, planar offset printing, dilitho printing, intaglio printing, letterpress printing, jet printing, silk screen printing, flexo printing, electrostatic printing, etc. can be used. It can depend on the printing method. When printing on a steel plate or the like, primer coating, base coat coating, etc. can be applied in advance.

Next, the clear paint is applied onto the printed layer formed as described above to form a coating layer. The clear paint can be applied using a spray gun, roll coater, flow coater, bar coater, or the like. After coating, the coating layer can be shaped by natural drying, baking, etc.

The patterned decorative material produced in this way has an uneven pattern on the surface of the coating film, and this uneven pattern causes diffuse reflection of light, so that it is possible to add depth to the printed pattern.

Moreover, since the coating layer contains polymer elastomer particles, the coating layer can give a moist feel when touched with the hand. For example, by printing wood grains on a steel plate and applying the clear paint, the printed wood grains can give the steel plate a visual and tactile feel just like real wood.
