ABSTRACT:
There provided a pressure-sensitive adhesive (PSA) composition constituting a PSA layer, which may exhibit a plurality of properties in a well-balanced manner, and a PSA sheet including the PSA layer. The composition is an aqueous PSA composition in which an acrylic polymer serves as a main component and the acrylic polymer is dispersed in water, and contains: A) acrylic polymer obtained by polymerizing a monomer raw material including alkyl(meth)acrylate as a main monomer, a first functional monomer having a first functional group to react with a hydrazino group, and a second functional monomer having a second functional group to react with a carbodiimide group; B) a hydrazine-based crosslinking agent; and C) a carbodiimide-based crosslinking agent.
