Abstract
A coating composition for polyolefinic films, especially poly-propylene films, which consists essentially of a solution of a dry three-component polymeric system comprising: (a) a first component consisting of acrylic homopolymers, copolymers or mixtures thereof; (b) a second component consisting of a polyester resin obtained by condensation; and (c) a third component consisting of medium or low viscosity nitrocellulose or mixtures thereof. The coated products and the coating process are also covered.

A coating composition for polyolefinic products which consists essentially of an organic solution of a dry polymeric system comprising:
- (a) about 50-60 parts by weight of a first component selected from the group consisting of acrylic homopolymers, copolymers and mixtures thereof;
- (b) a second component consisting of a polyester resin obtained by condensation, in a weight percent ratio of about 1-50%;
- and
- (c) about 10-30 parts by weight of a third component selected from the group consisting of medium viscosity nitrocellulose, low viscosity nitrocellulose and mixtures thereof.
A coating composition for polyolefinic films consisting essentially of an organic solution of a dry polymeric system as follows:
- (a) about 50-60 parts by weight of a methylmethacrylate/butylmethacrylate copolymer;
- (b) about 10-20 parts by weight of a polyester resin obtained by the condensation of phthalic anhydride and maleic anhydride with ethylene glycol;
- and
- (c) about 20-30 parts by weight of medium viscosity nitrocellulose.
