Abstract:
1. An aqueous dispersion adhesive composition comprising: an aqueous dispersion copolymer obtained by reacting of a reaction component comprising alkyl (meth)acrylate whose linear or branched alkyl group has 4 to 18 carbon atoms, (meth)acrylic acid, a phosphoric acid group-containing vinyl monomer and an alkoxysilyl group-containing vinyl monomer; and a crosslinking agent having reactivity with a carboxyl group, wherein an amount of the crosslinking agent is from 0.07 to 4 parts by weight per 100 parts by weight of the aqueous dispersion copolymer, and an elongation at 90° C. based on the following test of an adhesive layer made of the aqueous dispersion adhesive composition is 200% or less, wherein the test comprises subjecting the aqueous dispersion adhesive composition to heating to prepare an adhesive layer, and the adhesive layer thus prepared is formed into a cylindrical column shape having a cross section of 4.6 mm
