The pattern of the first pattern layer (1) is formed of granular colored inorganic particles (A) (preferably, granular colored inorganic particles (A1) (A2) of at least two colors or more). Such a 1st pattern layer (1) is formed with the composition (henceforth an "inorganic particle composition") containing a granular coloring inorganic particle (A) and a resin component.

When the first pattern layer (1) has granular colored inorganic particles, the color tone, texture, and the like can be changed. Moreover, the 1st pattern layer (1) has a granular design inorganic particle visually recognized as a pattern, respectively, and has the outstanding design property.

As long as the transmittance is satisfied, either colorless or colored ones can be used. The particle diameter of the granular transparent inorganic particles and / or the granular translucent inorganic particles (B) is preferably 0.1 to 5.0 mm.

  The resin component in the 1st pattern layer (1) of this invention plays the role which fixes the said granular colored inorganic particle (A), a granular transparent inorganic particle, and / or a granular translucent inorganic particle (B). Various resin components can be used as such a resin component. Examples of the resin component include solvent-soluble resins, non-water-dispersed resins, solvent-free resins, water-dispersed resins, and water-soluble resins.

The second pattern layer (2) of the present invention has a pattern of a plurality of colored particles. The pattern of the second pattern layer (2) is formed by flat colored resin particles (C) ((C1) (C2) or the like) of at least two colors. Such flat colored resin particles (C) are formed by a colorant containing a resin component and a pigment.

  In particular, the flat colored resin particles (C) in the second pattern layer (2) preferably include those having translucency. The flat colored resin particles having translucency are formed of a transparent coloring material. If such a transparent coloring material is used, it is possible to further enhance the texture and depth of a natural stone.

  The transparency of the transparent coloring material can be imparted by setting the concentration of the color pigment low. The concentration of the color pigment in the transparent colorant is preferably set to 5% by weight or less (more preferably 0.001% to 4% by weight, and still more preferably 0.01% to 3% by weight). .

  The flat colored resin particles (C) of the second pattern layer (2) are scattered on the first pattern layer (1), that is, flat coloration of two or more colors (more preferably 3 to 8 colors). A form in which the resin particles (C) are dispersed is desirable. In such a form, (C) forms a discontinuous layer, and the granular colored inorganic particles (A) of the first pattern layer and the flat colored resin particles (C) of the second pattern layer are exposed on the surface. It becomes a form. Thereby, the effect of the present invention can be further enhanced.

It is preferable to form a clear layer for the purpose of protection, particularly when it is applied to a site outside the structure where weather resistance is required. As such a clear layer, a form in which silica fine particles are fixed to the outermost surface of the laminate is preferable, and a structure in which silica fine particles are fixed with a resin component is more preferable. Silica fine particles have a high hardness of the particles themselves and can exhibit an excellent anti-staining effect by having many silanol groups on the particle surface.

  The average primary particle diameter of the silica fine particles is preferably 1 to 200 nm (more preferably 3 to 100 nm, still more preferably 5 to 60 nm). Within this range, a plurality of silica fine particles having different average primary particle diameters can be used in combination.

  As the resin component for immobilizing the silica fine particles, the same resin component as in the first pattern layer (1) can be used, and a water-soluble resin and / or a water-dispersible resin is particularly preferable. The mixing ratio of the resin component is preferably 5 to 500 parts by weight (more preferably 10 to 100 parts by weight, still more preferably 20 to 80 parts by weight) based on 100 parts by weight of the solid content of the silica fine particles.
