    Abstract: PROBLEM TO BE SOLVED: To obtain the subject coating material rich in flexibility and elasticity by adding a functional grafted polyurethane obtained by graft-polymerizing a specific monomer to a main chain comprising a specific polyurethane to form side chains. SOLUTION: This coating raw material used for adhesives, coatings or the like comprises a functional grafted polyurethane obtained by graft-polymerizing (B) a monomer of the formula to (A) a main chain comprising a polyurethane prepared by the reaction of (i) a diol having one or more double bonds in the molecule with (ii) a diisocyanate (for example, 4,4-methylenediphenyldiisocyanate) to form side chains. The component i is preferably a diol having one or more vinyl groups in the molecule, especially polybutadienediol having vinyl groups at the ends (side chains). For the synthesis reaction of the polyurethane, a polymer diol such as hydrogenated polybutadienediol or a polyesterdiol may together be used.
