<P>PROBLEM TO BE SOLVED: To provide an antireflection film which can be easily manufactured, gives a hard performance such as scratch resistance and weatherability to the uppermost layer of the antireflection film and can prevent the occurrence of cracking on the uppermost layer even for a deformation of a transparent plastic substrate film. <P>SOLUTION: In the antireflection film, a low refractive index layer 3 essentially consisting of ionizing radiation curable resin composition which includes superfine particles having particle diameter of ≥5 nm and ≤50 nm and refractive index of ≥1.35 and ≤1.45 is formed directly or via other layer on the transparent plastic substrate film 1 as the surface layer. Therein, the low refractive index layer 3 has a refractive index lower than the refractive index of the under layer with which the low refractive index layer 3 is in contact directly and the low refractive index layer 3 is constituted such that the superfine particles are included by ≥30 pts.wt. and ≤300 pts.wt. with respect to ionizing radiation curable resin 100 pts.wt. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
