ABSTRACT:
The grafting reaction product of the present invention includes a main chain having a polymer selected from one of a polyester and a polyester polyurethane consisting mainly of the polyester, the polyester containing 60 mole % or more of an aromatic dicarboxylic acid for the amount of the total carboxylic acids. The grafting reaction product further includes a plurality of side chains which are polymers of radical polymerizable monomers, said radical polymerizable monomers having at least 30% by weight of the combination of at least one electron accepting monomers (A) having an e value of 0.9 or more and at least one electron donative monomers (B) having an e value of -0.6 or less for the amount of the total radical polymerizable monomers, and at least 10% by weight of an aromatic radical polymerizable monomer for the amount of the total radical polymerizable monomers. According to the present invention, the plurality of side chains are grafted into the main chain to form the grafting reaction product.
