<P>PROBLEM TO BE SOLVED: To provide an inexpensive anti-reflection stack that has a low refractive index, has superior physical strength and antifouling properties, and also has superior productivity. <P>SOLUTION: In the anti-reflection stack obtained by laminating a hard coat layer (HC layer) and a low refractive index layer (L layer), the HC layer is made of a resin containing as a principal component an acrylic compound having at least three or more polymerizable unsaturated bonds such as a vinyl group in the molecule, wherein the surface of the HC layer to form the grain boundary with the L layer has an extra-fine rough surface structure, and also, the L layer is formed by being coated with a low refractive index coating agent Si containing as a principal component alkoxide, the hydrolyzate thereof, a fluorine-containing silicon compound and the hydrolyzate thereof. <P>COPYRIGHT: (C)2011,JPO&INPIT |
