Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
A METHOD FOR PREPARING LAMINAR STRUCTURES OF POLYVINYL FLUORIDE AND UNSATURATED POLYESTERS WHICH COMPRISES SUBJECTING AT LEAST ONE SURFACE OF A POLYVINYL FLUORIDE FILM STRUCTURE TO AN ELECTRICAL DISCHARGE IN A GASEOUS ATMOSPHERE CONSISTING ESSENTIALLY OF AMMONIA; CONTACTING AT LEAST ONE TREATED SURFACE OF SAID POLYVINYL FLUORIDE FILM STRUCTURE WITH AN UNSATURATED POLYESTER POLYMERIC MATERIAL CONSISTING ESSENTIALLY OF AT LEAST ONE UNSATURATED ORGANIC LINEAR POLYMERIC ESTER HAVING RECURRING ETHYLENIC UNSATURATION AND AT LEAST ONE ADDITION-POLYMERIZABLE ETHYLENICALLY UNSATURATED ORGANIC MONOMER; AND CURING SAID POLYVINYL FLUORIDE FILM AND UNSATURATED POLYESTER TO FORM A CURED LAMINAR STRUCTURE COMPRISING AT LEAST ONE LAYER OF POLYVINYL FLUORIDE INTEGRALLY BONDED TO AT LEAST ONE LAYER OF SAID UNSATURATED POLYESTER.
Claim 2
