AI Technical Summary

Problems solved by technology

Therefore, sometimes the desired pattern cannot be formed due to the destruction of the capsule due to the coating conditions
Especially when roller coating or brush coating is applied, problems such as color bleeding from the particles are likely to occur
In addition, since the paint in this publication is a liquid in the capsule, there is also the problem that the formed pattern is easily changed due to the temperature or coating pressure during coating.

Embodiment

[0103] Hereinafter, the characteristics of the present invention will be further clarified using examples.

[0104] In addition, the following raw materials were used for the manufacture of paint.

[0105] ・Water-dispersible resin A: acrylic resin emulsion (styrene-methyl methacrylate-2-ethylhexyl acrylate copolymer, minimum film forming temperature 3°C, pH 8.8, solid content 50% by weight)

[0106] ・Water-dispersible resin B: acrylic resin emulsion (styrene-methyl methacrylate-2-ethylhexyl acrylate copolymer, minimum film forming temperature 2°C, pH 6.2, solid content 50% by weight)

[0107] ・Water-dispersible resin C: carboxyl group-containing acrylic resin emulsion (methyl methacrylate-butyl acrylate-acrylic acid copolymer, minimum film forming temperature 0°C, pH 8.2, solid content 50% by weight)

[0108] ・Water-dispersible resin D: acrylic resin emulsion (styrene-butyl acrylate copolymer, minimum film forming temperature 0°C, solid content 50% by weight)

Embodiment 1-1

[0164] For stone slabs pre-coated with a gray protective layer, use a sand bone roller with a coating rate of 0.6kg / m 2 To coat the multi-color pattern paint that mixed the paint composition 1-A and the paint composition 1-B in a weight ratio of 50:50, after drying at room temperature for 24 hours, observe the state of the paint film. In Example 1-1, a mixture of white and gray was present, and a smooth pattern coating film with high mappability was formed. Abnormality of colored particles was not observed either.

Embodiment 1-2

[0166] Except that as the multicolor pattern coating, the coating composition 1-A, the coating composition 1-B and the coating composition 1-C were mixed in a weight ratio of 80:10:10, and carried out in the same manner as in Example 1-1. coated.

[0167] In Example 1-2, white, gray and black are mixed, and a smooth and high-mapping pattern coating film can be formed. Abnormality of colored particles was not observed either.

Abstract

Practical water-in-water type multicolor coating compositions capable of forming a coating film having excellent surface smoothness; and a method of coating with the coating compositions. One of the water-in-water type multicolor coating compositions is characterized by comprising a matte clear coating material containing a water-compatible resin and a loading pigment having a refractive index of 1.4 to 1.7 and, dispersed in the coating material, at least one kind of flat colored gel particles. The other water-in-water type multicolor coating composition is characterized by comprising a clear coating material containing a water-compatible resin and, dispersed in the coating material, at least one kind of flat colored gel particles, the flat gel particles being a gel derived from a water-compatible resin (a), a coloring pigment (b), water (c), and a reactive compound (d) capable of reacting in the presence of water. Also provided is a method of forming a patterned surface, characterized by applying a colored matte primer coating material on a building as a base to form a primer layer and then applying the water-in-water type multicolor coating composition by roll coating or brush coating to form a topcoat layer.

Description

technical field [0001] The invention relates to a new water-in-water type multi-color pattern paint composition. Background technique [0002] In the past, paints called matt paints were often used to coat the interior and exterior surfaces of buildings such as walls, ceilings, and doors. A typical matte paint is a paint specified in JIS K5663 "synthetic resin emulsion paint". Such matte paints can express various colors by tinting with pigments. However, the color obtained by matte paint is a single color, and it is not possible to apply a pattern showing a mixture of multiple colors at one time. [0003] In response to this, various coating compositions capable of displaying multicolored patterns by one coating have been proposed. About the idea of ​​the composition of such coating, be to start from the patent of P.BUSCH, the U.S. Patent No. 2591904 that J.C.ZOLA does, the Japanese Patent No. 231698 and the practical oil-in-water type polychrome pattern coating is repre...
