Abstract
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.
