Patent ID: 7776937

Claim:
A photocurable composition for forming an anti-fogging coating, comprising: (A) a urethane compound containing at least two (meth)acryloyl groups and a polyoxyalkylene chain in a molecule thereof; (B) a compound having at least two (meth)acryloyl groups and at least two hydroxyl groups in a molecule thereof, obtained by reacting at least two components consisting of an epoxy compound and (meth)acrylic acid; (C) a compound having an ethylenic unsaturated group other than the components (A) and (B); and (D) a photopolymerization initiator, the urethane compound (A) being a reaction product of a polyisocyanate compound (a-1), a polyalkylene glycol (a-2), and a compound (a-3) containing a hydroxyl group and a (meth)acryloyl group, at least a portion of the compound (C) being a urethane compound (C-1) obtained by reacting a polyisocyanate compound (c-1), a hydrophobic polyol (c-2) and a compound (c-3) containing a hydroxyl group and a (meth)acryloyl group, the hydrophobic polyol (c-2) being a polyester polyol obtained by reacting a polyvalent alcohol and a polyvalent carboxylic acid, the composition containing 20 to 70% by weight of the urethane compound (A), 10 to 60% by weight of the compound (B), and 20 to 70% by weight of the compound (C) based on the total solid weight of the compound (A), the compound (B) and the compound (C), and the compound (C) containing 10 to 50% by weight of the compound (C-1) based on the total solid weight of the compound (A), the compound (B) and the compound (C).
