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.
