Abstract
An active energy ray-curable composition includes (A) a condensate having a weight average molecular weight of 20,000 or less, and (B) a photoacid generator, with the condensate (A) being obtained by hydrolysis/condensation of: (I) a silane compound containing a hydrolyzable silyl group represented by formula (I): R—(SiR(OR). A ratio (Y/X) of Y to X is 0.2 or less, where X represents the number of moles of ORgroups directly bonded to silicon atoms in the silane compound (I) which is a starting material of the condensate (A) and Y represents the number of moles of ORgroups directly bonded to silicon atoms in the condensate (A).
