Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 74 words
A laminate adapted for the protection of motor vehicle bodies from abrasion and corrosion damage when secured thereto which consists essentially of: (a) a film component having a thickness of at least about 200 microns comprising an internally plasticized vinyl chloride copolymer resin and an effective amount of a polymeric additive to enhance the flexibility characteristics of the film; and (b) a layer of pressure sensitive adhesive attached to one side of the film.
Claim 2
Dependent Claim 74 words
A laminate adapted for the protection of motor vehicle bodies from abrasion and corrosion damage when secured thereto which consists essentially of: (a) a film component having a thickness of at least about 200 microns comprising an internally plasticized vinyl chloride copolymer resin and an effective amount of a polymeric additive to enhance the flexibility characteristics of the film; and (b) a layer of pressure sensitive adhesive attached to one side of the film.
