Abstract
To provide an antifogging agent composition having excellent sustainability of antifogging performance. An anti fogging agent composition includes a copolymer (A), a polyfunctional blocked isocyanate compound (B), and a surfactant (C). The copolymer (A) is formed of 35 to 90 parts by weight of the monomer (A-1), 5 to 60 parts by weight of the monomer (A-2), and 5 to 30 parts by weight of the monomer (A-3) per 100 parts by weight of the copolymer (A). An NCO/OH ratio obtained by dividing an isocyanate group content (NCO) of the polyfunctional blocked isocyanate compound (B) by a hydroxyl group content (OH) of the copolymer (A) is within a range from 0.1 to 1.5. The surfactant (C) includes 1.00 to 10.0 parts by weight of the anionic surfactant (C-1) and 0.01 to 3.00 parts by weight of the cationic surfactant (C-2) per 100 parts by weight of the copolymer (A).
