A primer composition composed of 1 to 100 parts by weight of a chlorinated carboxyl group-containing a-olefin polymer and 100 parts by weight of an organic solvent therefor, the improvement wherein (i) said chlorinated carboxyl group-containing a-olefin polymer is a post-chlorination product [C] of a graft-modified propylene polymer [B] having a chlorine content of 10 to 35% by weight, said graft-modified propylene polymer [B] having an acid value of 6 to 187 mg-KOH/g-polymer and obtained by grafting an unsaturated dicarboxylic acid anhydride to a propylene polymer [A] having an intrinsic viscosity [η], determined at 135°C in decalin, of 0.6 to 10 dl/g and comprising 70 to 100 mole% of propylene and 0 to 30 mole% of an a-olefin other than propylene, and (ii) said solvent is an organic solvent boiling at about 60° to about 200 °C.

摘要： A surface treating agent for use as an undercoat when painting a shaped article of a polyolefin comprises a solution in an organic solvent of a propylene-ethylene copolymer having a monoalkyl ester of a monoolefinic dicarboxylic acid, such as monomethyl maleste, grafted thereto, the propylene-ehylene copolymer having a propylene content of 50 to 75 mole %, and a crystallinity determined by an X-ray diffraction method, of 2 to 20%, the esterification degree of the alkyl ester of the monoolefinic dicarboxylic acid being 45 to 100% if the esterification degree is taken as 200% when all of the carboxyl groups of the dicarboxylic acid are esterified, the amount of the monoalkyl ester grafted being 0.5 to 15% by weight, the grafted propylene-ethylene copolymer having an intrinsic viscosity [η] of at least 0.3 and being dissolved in an amount of 10 to 100 kg per cubic meter of the organic solvent. The surface treating agent when used as an undercoat greatly improves the adhesion of a paint to a polyolefin shaped article, and has excellent storage stability.
