Patent ID: 8530546

Claim:
An actinic radiation-curable composition comprising: a reaction product (A) obtained by reacting an alkoxysilane compound (a1) represented by Formula (1) below and inorganic oxide microparticles (a2) in the presence of water and an organic solvent, and a compound, other than the reaction product (A), having a total of 2 to 10 (meth)acryloyl and/or maleimide groups in one molecule, (P—SiO 3/2 ) 1-a (P—Si(R 0 )O 2/2 ) a (O 1/2 R 3 ) z (1) wherein, in Formula (1), P denotes a group represented by Formula (2) below, R 3 denotes a hydrogen atom or a monovalent organic group, R 0 denotes a monovalent organic group, a is 0 or a positive number and satisfies 0≦a<1, z is a positive number and satisfies 0.1≦z≦2, P, R 0 , and R 3 may each comprise two or more different types of groups in one molecule, and R 0 and R 3 may each be identical groups or different groups in one molecule, wherein, in Formula (2), R 1 and R 2 independently denote a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, or an aryl group, or R 1 and R 2 denote hydrocarbon groups together forming one 5-membered ring or 6-membered ring, and R denotes a divalent organic group.
