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.

An acid resistant member comprising a non-plasticized film of a polyvinyl chloride homopolymer secured at one side to a balanced biaxially oriented film and at the opposite side to a substrate by an adhesive, said adhesive comprising a binder selected from the class consisting of styrene isoprene copolymers and polyisobutylene elastomers having a Mooney viscosity index between about 35 and 55, a non-hydrolyzable resin tackifier, a non-hydrolyzable resin plasticizer, 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.
