PROBLEM TO BE SOLVED: To quickly bond to a variety of substrates, to be transparent in a one-part coating type, to have excellent weather resistance, excellent moisture resistance, and to have excellent adhesion to a variety of substrates. Providing coatings. SOLUTION: A block copolymer having the following representative structure and a coating composition containing the same. Embedded image Where m = 1-20, n = 1-20, p = 0 or 1, R 1 = monomeric or polymeric substance containing only one functional group capable of reacting with isocyanate groups. R 2 = groups derived from all available aliphatic, cycloaliphatic or shielded aromatic diisocyanates. R 3 = preformed polymer block or similar hybrid. X = Or any combination of |
