PROBLEM TO BE SOLVED: To provide a coating material exhibiting excellent nonslip performance at a low cost.SOLUTION: The coating material contains: a copolymer (A) obtained from 50-99.9 pts.wt. of an alkyl (meth)acrylate and other copolymerizable vinyl monomers; a polyisocyanate compound (B) having on average three or more isocyanate groups in one molecule and having an isocyanate content of 5-30%; and an organic solvent (C). The copolymer (A) has a glass transition temperature of -40 to 10°C, a hydroxyl value of 10-100 mg KOH/g, and a weight-average molecular weight of 10,000-100,000.SELECTED DRAWING: None |
