PROBLEM TO BE SOLVED: To provide a basic design of a decorative board having high homogeneous designability with unity while maintaining favorable nonflammable performance of an inorganic substrate capable of: stably adding various additional functions in response to environment of an installation site; selectively using various decorative boards adding numerous performances including nonflammability by optimizing the installation site; and maintaining high nonflammable performance in the whole installation site.SOLUTION: There is provided a decorative board having a base coat layer and a decorative layer containing a coloring agent in this order and further having a clear layer formed thereon. The optical characteristic of a decorative board surface is within a specific range compared with that before the clear layer formation, and the seeming difference of those optical characteristics is lessened to a degree in which visible discrimination is almost impossible.SELECTED DRAWING: Figure 1 |
