Abstract

A method for producing a self-adsorbing foam sheet is provided. The method comprising making a resin composition for a self-adsorbing foam sheet, the resin composition including: 100 parts by mass of a (meth)acrylic acid ester copolymer resin which includes an N-methylol group, and whose glass transition temperature is −10° C. or less; and 1 to 20 parts by mass of a carbodiimide crosslinking agent; foaming the resin composition, to obtain foam of the resin composition; and shaping the foam into a sheet and after that, carrying out crosslinking reaction on the (meth)acrylic acid ester copolymer resin.
