ABSTRACT:
A resin composition obtained by adding maleic anhydride to an unsaturated polyester resin composition comprising (I) an unsaturated polyester, (II) a styrene monomer, and (III) at least one polymerizable unsaturated compound, in limited amounts is low in viscosity, excellent in transparency and adhesiveness, able to prevent the generation of surface defects, and thus suitable for treating cathode-ray tubes.
