PROBLEM TO BE SOLVED: To provide a hard coat film, capable of improving an adhesiveness between a plastic film and a hard coat while keeping a surface hardness of 4 or above by pencil test and a surface flatness, and diminishing a generation of crack and curl in bending the film. SOLUTION: Fine particles having a particle diameter in the range of 10 nm-5 μm are homogeneously dispersed in a hard-coat film layer at a ratio of 10-500 wt.pts. to 100 wt.pts. of a radiation-curing type (meth)acrylate having a (meth)acryloyl group. The hard-coat film layer is installed on at least one side of the plastic film, the above fine particles have also a kind of two or above, and the particle diameter of each kind of fine particles is set to be narly same, wherein an average particle diameter of one kind of fine particles is twice or above of another kind of fine particles, and a radius of curvature of curl is 20 cm or above. |
