Patent ID: 8436124

Claim:
A urethane resin that is formed by polymerizing (a) an acrylic resin in which a ratio [A]/([A]+[B]) is from 80% to 100%, where [A] represents a molar content of hydroxyl groups of side chains having less than 10 carbon atoms and [B] represents a molar content of hydroxyl groups of side chains having 10 or more carbon atoms; and a hydroxyl value is from about 70 mg KOH/g to about 400 mg KOH/g; (b) at least one silicone selected from compounds represented by a general formula (1) below where R 1 represents an amino group, a hydroxyl group, a methoxy group, or an ethoxy group; R 2 represents a methyl group, a phenyl group, or an ethyl group; and n is from 3 to 1,000; and (c) an isocyanate, wherein the urethane resin has a Martens hardness of from 1 N/mm 2 to 200 N/mm 2 at 150° C. and a recovery rate of from 80% to 100% at 150° C.
