Curing of a pressure-sensitive adhesive resin based on an acrylic interpolymer containing pendant carboxylic acid or anhydride groups is effected through reaction with a 2-oxazoline cross-linking agent. The polyfunctional 2-oxazoline are particularly useful for this purpose and provide resins of substantially improved cohesive strength.
