The present invention is an adhesive composition that is characterized by including (A) a polymer comprising a structural unit having a hydroxy group in a side chain, (B) a compound having two or more isocyanate groups, (C) a bismuth carboxylate, and (D) a tertiary amine having a pKa of 6 or more. The polymer (A) may include further a structural unit having a urethane bond and a polymerizable unsaturated bond in a side chain.

Pressure-sensitive adhesive composition, process for producing same, and pressure-sensitive adhesive film

The present invention is a method for producing a polyfunctional polymer that contains a structural unit having a urethane bond and a polymerizable unsaturated bond in a side chain, and is characterised by including a reaction process in which a polymer (P) containing a structural unit (a) having a hydroxy group in a side chain and a monomer (M) having an isocyanate group and a polymerizable unsaturated bond are reacted in the presence of a bismuth carboxylate.
