PURPOSE:To remarkably improve the adhesive property while maintaining various properties such as color developing property etc. by making a solution of a copolymer of a predetermined amount of monomer which is copolymerizable with a predetermined weight of (meth)acrylamide and N- vinylpyrrolidone as an effective component. CONSTITUTION:A solution of a copolymer made of 52-98 weight % of (A) (meth) acrylamide, 1.0-18 weight % of (B) N-vinylpyrrolidone and, 1.0-30 weight % of monomer which is copolymerizable with (A) and (B) is used as an effective component. Moreover, where polyvinylalcohol is present, a solution of a copolymer made of 52-98 weight % of (meth)acrylamide, 1.0-18 weight % of N- vinylpyrrolidone and, 1.0-30 weight % of monomer copolymerizable with these is made an effective component. |
