Abstract:
1. An antifogging paint composition comprising: a block copolymer containing a hydrophilic polymer part formed from a water-soluble vinyl monomer and a cross-linkable vinyl monomer having a cross-linking functional group, and a hydrophobic polymer part formed from a non water-soluble vinyl monomer, wherein the weight ratio of the water-soluble vinyl monomer and the cross-linkable vinyl monomer is 70:30 to 99:1, and wherein the ratio of the hydrophilic polymer part in the copolymer is 50 to 95% by weight, wherein the copolymer is a block copolymer in which the water-soluble vinyl monomer is N,N-dimethyl acrylic amide, the cross-linkable vinyl monomer is N-methylol acrylic amide, and the non water-soluble vinyl monomer is methyl methacrylate; and an acidic alkyl phosphate having an alkyl group having 1 to 8 carbon atoms, wherein the content of the acidic alkyl phosphate is 0.01 to 3% by weight with respect to the copolymer.
