A hard coat film having an easily slipping property which comprises a plastic film and a hard coating layer of 1 to 15 .mu.m thickness made from an ultraviolet curable resin on the plastic film, wherein the hard coating layer contains particles of a high molecular weight polyester resin dispersed therein and the surface of the hard coating layer is provided with 3 to 200 protrusions of a diameter of 0.05 to 3 .mu.m and a height of 0.01 to 2 .mu.m per 100 .mu.m.sup.2 of the surface, and a process for producing the hard coat film. The hard coat film has a low haze value, a good transparency, an excellent resistance to scratch, a low kinematic friction coefficient, and an excellent slipping property both between coated surfaces and between a coated surface and a surface having no treatment.
A hard coat film having an easily slipping property which comprises a plastic film having a glass transition temperature of at least 20.degree. C., and a hard coating layer of 1 to 15 .mu.m thickness made from a photo-polymerization initiator-containing ultraviolet light curable acrylic resin on the plastic film, wherein the hard coating layer contains particles of a polyester resin having a weight average molecular weight of at least 5,000 dispersed therein, and the surface of the hard coating layer is provided with 3 to 200 protrusions of a diameter of 0.05 to 3 .mu.m and a height of 0.01 to 2 .mu.m per 100 .mu.m.sup.2 of the surface.
A process for producing a hard coat film having an easily slipping property comprising coating a plastic film having a glass transition temperature of at least 20.degree. C. with a coating material which comprises an ultraviolet light curable acrylic resin containing a photo-polymerization initiator, a polyester resin having a weight average molecular weight of at least 5,000, and a solvent, said coating material containing from 0.1 to 20 parts by weight of the polyester resin per 100 parts by weight of the ultraviolet light curable acrylic resin, removing the solvent from the coated layer by vaporization, curing the coated layer by irradiation with ultraviolet light, and forming a hard coating layer having protrusions of a diameter of 0.05 to 3 .mu.m and a height of 0.01 to 2 .mu.m at the surface thereof.
