    摘要: PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive having high solvent resistance and exhibiting improved adhesive property etc.SOLUTION: A silylated polyurethane composition contains a silylated polyurethane prepolymer obtained by a silylation of a polyurethane prepolymer derived from a reaction of polyester polyol having at least 2.00 hydroxy groups as average and polyisocyanate. 95% or less of all isocyanate groups or all hydroxy groups present in the prepolymer are silylated. The silylated polyurethane composition contains at least one catalyst selected from a group consisting of dialkyltin dicarboxylate, a tertiary amine, and stannous carboxylate for reaction of the prepolymer and further at least one adhesive selected from various elastomers as complementary adhesive.
