Abstract
Abstract Chemically-resistant adhesives formed using non-hydrolyzable hard and soft resins. Chemically-resistant labels are provided by using the adhesive to adhere an image-bearing film of polyvinyl chloride to a protective film, and to a carrier. The labels are particularly resistant to acids and have a reduced tendency to shrink or distort when affixed to battery surfaces at elevated temperatures.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
156 words
An acid-resistant label comprising a non-plasticized film of a polyvinyl chloride homopolymer secured at one side to a polypropylene balanced biaxially oriented film and at the opposite side to a substrate by an adhesive, said adhesive comprising a styrene butadiene compolymer binder having a Mooney viscosity index between about 35 and 55, a non-hydrolyzable hard resin tackifier having a softening point in the range from about 80° C. to about 100° C., a non-hydrolyzable soft resin plasticizer having a softening point range of about 5° C. to about 10° C., and a stabilizer, said binder and tackifier being present in a weight ratio in the range from about 1:1 to about 1:1.5, said tackifier and plasticizer being present in a weight ratio in the range from about 6:1 to about 15:1, and said stabilizer being present in a concentration in the range from about 0.5% to about 3% by weight of the binder and tackifier combined.
Claim 2
Dependent Claim
