Abstract
Abstract A coating composition for polyolefinic films, especially polypropylene films, which consists essentially of a solution of a three-component polymeric system comprising: (a) about 50 to 80% of saturated polyesters, unsaturated polyesters or mixtures thereof (b) polymers and copolymers of acrylic esters; and (c) epoxy resins, the ratio of each of components (b) and (c) being from about 1 to 49% and being selected as to make up the total percentage of the polymeric system. The coated products and the coating process are also covered.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
108 words
As new industrial products, polyolefinic films coated with a composition consisting essentially of a solution of a dry polymeric system comprising: (a) about 50 to 80 parts by weight of a first component selected from the group consisting of saturated polyesters, unsaturated polyesters and mixtures thereof; (b) a second component selected from the group consisting of polymers and copolymers of acrylic esters; and (c) a third component consisting of an epoxy resin; the second and third components being of about 1 to 49% parts by weight of the system and being selected so as to make up the balance of the total percentage of the dry polymeric system.
Claim 2
Dependent Claim
108 words
