The decorative layer 14 is formed in a laminate or the like by repeatedly applying a light-transmitting clear paint on the substrate.

With this configuration, the decorative layer 14 can be cured quickly, and when the decorative layer 14 is formed as a laminate, the drying and curing time of the decorative layer 14 is shortened, and the decorative The decorative material 11 can be manufactured.

Further, the technical idea grasped from the above embodiment will be described below. The architectural decorative material according to any one of claims 1 to 4, wherein the main material layer is formed from an aggregate coloring coating material having a thermosensitive gelling property.

With this structure, the adhesiveness between the main material layer and the decorative layer can be enhanced, the durability of the decorative material for construction can be improved, and the main material layer and the decorative layer can be quickly cured. Can be. -The said aggregate coloring coating material is a skin type coating material.
An architectural decorative material according to any one of claims 1 to 4.

With this configuration, a predetermined color or pattern can be easily developed, and the texture of the decorative material for construction can be easily and effectively improved. The architectural decorative material according to any one of claims 1 to 4, wherein a protective clear layer formed of a paint made of a transparent resin is provided on the decorative layer.

With this structure, the main material layer and the decorative layer can be protected without impairing the appearance of the crystal pattern of the decorative layer, and the durability of the decorative material for construction can be improved.

[0088]

As described above, according to the present invention, the following effects can be obtained. According to the architectural decorative material of the first aspect of the present invention, since the decorative layer capable of expressing a crystal pattern is provided, it is possible to enhance the texture, have good decorativeness, and effectively improve the appearance. it can.

According to the architectural decorative material of the second aspect of the present invention, in addition to the effect of the first aspect of the present invention, when the decorative layer is laminated, the main material layer and the decorative layer The boundary can be made clear and a crystal pattern due to light reflection or transmission interference can be easily developed. In the state where the decoration layer is embedded, the main material layer and the decoration layer are integrally formed, and the texture can be made closer to the texture of natural stone in which crystals are studded. Therefore, the texture of the architectural decorative material can be effectively enhanced, and more excellent decorativeness can be imparted.

According to the architectural decorative material of the third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, the texture is more effectively enhanced and a clear crystal pattern is exhibited. Can be done.
