    • An aqueous primer composition for use in applying to polyolefin resin substrates which is excellent in adhesiveness to polyolefin resin substrates, water resistance and gasoline resistance and which is free from the problems of fire and environmental pollution. The primer composition comprises a resin component (a) of 100 parts by weight of modified polyolefin which is prepared by modifying polyolefin with an alpha , beta -unsaturated carboxylic acids and which contains 0.05 to 0.5 equivalent of free carboxylic acid groups per 100 g, with the other resin component (b) of 5 to 500 parts by weight of modified resin having both ethylenically unsaturated double bonds and free carboxylic acid groups, which modified resin is prepared by adding an alpha , beta -unsaturated dicarboxylic anhydride to a drying oil or a conjugated diene polymer or conjugated diene copolymer and then opening the ring of the acid anhydride group; and is prepared by neutralizing at least a part of free carboxylic acid groups of said modified polyolefin of component (a) and/or said modified resin of component (b) with a base and then dissolving or dispersing them in water.
