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 that of the binder (B). The average particle diameter d (micrometers) of the spherical particles (A) fulfills the following inequality (1):0.3tࣘdࣘ3.0t (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.Field of SearchIron oxide or aluminum oxideHeavy metal or aluminum or compound thereof Polymeric or resinous material WEAR-RESISTANT LAYER Including a second component containing structurally defined particles Continuous and nonuniform or irregular surface on layer or component (e.g., roofing, etc.) Particulate matter Of polyamidoester (polyurethane, polyisocyanate, polycarbamate, etc.) | |
