(57) [Summary] [Purpose] Cross-linking has a good balance between adhesive strength and cohesive strength and is excellent in all characteristics such as room temperature curing property, storage stability, weather resistance, heat resistance, water resistance, and substrate adhesion. A type acrylic pressure-sensitive adhesive is provided. [Structure] A polymercapto compound containing two or more mercapto groups in one molecule and an acrylic copolymer containing a functional group reactive with a mercapto group are crosslinked. |
