Patent ID: 7982953

Claim:
An antireflection film comprising: a transparent plastic film substrate; a hard coat layer; and a low refractive index layer, in this order, wherein the low refractive index layer is formed by a curable composition comprising: (a) an inorganic fine particle; (b) at least one of: a cationic polymerizable compound having a silyl group within the molecule; a hydrolysate of the cationic polymerizable compound having a silyl group within the molecule; and a partial condensate of the cationic polymerizable compound having a silyl group within the molecule; (c) a photo-cationic polymerization initiator; wherein an amount of at least one compound having a cationic polymerizable group is 70 mass % or more, based on binder components of the curable composition, wherein the at least one compound having a cationic polymerizable group comprises said at least one of the cationic polymerizable compound having a silyl group within the molecule, the hydrolysate of the cationic polymerizable compound having a silyl group within the molecule, and the partial condensate of the cationic polymerizable compound having a silyl group within the molecule; wherein the cationic polymerizable compound having a silyl group within the molecule is an organosilane represented by formula [A]: (R 1 ) m Si(R 2 )(X 10 ) 3-m wherein R 1 represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group, R 2 represents a monovalent substituent having a cationic polymerizable functional group, X 10 represents a hydroxyl group or a hydrolyzable group, and m represents an integer of 0 to 2.
