Abstract
A decorative material including a substrate and an abrasion-resistant coating layer formed thereon. The abrasion-resistant coating layer includes spherical particles (A) having an average particle diameter of 3 to 50 micrometers, and a binder (B) including crosslinkable resins. The amount of the spherical particles (A) is from 5% to 50% by weight of the total amount of the components (A) and (B). The hardness of the spherical particles (A) is higher than of the binder (B), and The average particle diameter d (micrometers) of the spherical particles (A) fulfills the following inequality (1): EQU 0.3t.ltoreq.d.ltoreq.3.0t (1) wherein "t" is an average thickness (micrometers) of the coating layer. Thus, the relationship between the average thickness of the coating layer and the average particle diameter of the spherical particles is strictly controlled, so that a decorative material which is excellent in both flexibility and abrasion resistance (scratch resistance) can be successfully obtained.
