The present invention provides a photocuring method capable of quickly and efficiently obtaining a crosslinked product (resin), a compound used in the photocuring method, and a photocurable resin composition containing the compound. n n The present invention relates to a photocuring method wherein step 2 is performed after step 1, a compound used in the photocuring method, and a photocurable resin composition containing the compound. n n Step 1: in the presence of (A) a compound having a carbonyl group generating a radical and a carboxyl group which decarboxylates by irradiation with light, (B) a silane coupling agent having a mercapto group or a (meth) acryl group reacts with (C) water under under acidic conditions to obtain (D) a silane compound having a mercapto group or a (meth) acryl group and at least one silanol group. n n Step 2: in the presence of (A) and (E) a compound having na carbonyl group generating a radical and a group capable of decarboxylating to generate a base by irradiation with light, the compound (A) and the compound (E) are irradiated with light to decarboxylate the carboxyl group of the compound (A) and generate a base from the compound (E) to make the inside of the reaction system alkaline, and generates radicals from the compound (A) and the compound (E), so as to produce a crosslinked product containing a constituent unit derived from the silane compound (D) from the silane compound (D) and, if necessary, (F) a compound having two or more polymerizable unsaturated groups. |
