Patent ID: 7153563

Claim:
A hard coat film comprising a substrate film having a thickness of 20 to 300 μm and a hard coat layer disposed on at least one face of the substrate film, wherein the hard coat layer has a thickness of 2 to 20 μm and comprises 100 parts by weight of (A) a resin curable by an ionizing radiation, said resin curable by an ionizing radiation being at least one prepolymer polymerizable by a radical polymerization selected from the group consisting of a polyester acrylate prepolymer, an epoxyacrylate prepolymer, a urethane acrylate prepolymer and a polyol acrylate prepolymer, and 0.1 to 10 parts by weight of (B) a nonionic surfactant having a HLB of 2 to 15, said nonionic surfactant being an ester of a fatty acid which is at least one compound selected from the group consisting of (a) an ester of a fatty acid selected from the group consisting of propylene glycol monostearate, propylene glycol monolaurate, diethylene glycol monostearate, diethylene glycol monolaurate, glycerol monostearate, sorbitane sesquioleate, sorbitane monooleate, sorbitane monostearate, sorbitane monopalmitate and sorbitane monolaurate, and (b) an ester of a fatty acid to which a polyoxyalkylene group is added, which is selected from the group consisting of castor oil cured with polyoxyethylene, polyoxyethyleneglycerol, monostearate, polyoxyethylene (4) sorbitane, monostearate, polyoxyethylene (20) sorbitane, monostearate, polyoxyethylene (4) sorbitane tristearate, polyoxyethylene (5) sorbitane monooleate, polyoxyethylene (5) sorbitane monooleate, polyoxyethylene (20) sorbitane trioleate, polyoxyethylene (4) sorbitane monolaurate, polyoxyethylene glycol 400 monooleate, polyoxyethylene glycol 400 monostearate, polyethylene glycol 400 monolaurate and polyoxyethylene (4) sorbitane monolaurate, said hard coat layer being formed by applying a coating fluid comprising said components (A) and (B) to at least one face of the substrate film to form a coating layer and curing the coating layer with an ionizing radiation.
