An object of the present invention is to provide a photocuring method, which makes it possible to rapidly and efficiently obtain a crosslinked product (resin), a compound used in the photocuring method, and a photocuring resin composition containing the compound.
The present invention relates to a photocuring method, which comprises a step 1 and a step 2 performed after the step 1, a compound used in the photocuring method, and a photocuring resin composition containing the compound.
Step 1: this is a step in which in the presence of (A) compound having a carbonyl group generating a radical by photoirradiation and a carboxyl group decarboxylated by photoirradiation, (B) silane coupling agent having a mercapto group or a (meth)acryl group is reacted with (C) water under acidic conditions to obtain (D) silane compound having a mercapto group or a (meth)acryl group and at least one silanol group.
Step 2: this is a step in which in the presence of the compound (A) and (E) compound having a carbonyl group generating a radical by photoirradiation and a group generating a base by being decarboxylated by photoirradiation, the compound (A) and the compound (E) are irradiated with light to create alkaline conditions in a reaction system by decarboxylating the carboxyl group of the compound (A) and generating a base from the compound (E), and radicals are generated from the compound (A) and the compound (E) to generate a crosslinked product containing a constitutional unit derived from the silane compound (D) from the silane compound (D) and, if necessary, from (F) compound having two or more polymerizable unsaturated groups.
本发明的一个目标是提供一种光固化方法,该方法使得能够快速高效地获得交联产物(树脂),以及用于光固化方法的化合物和含有该化合物的光固化树脂组合物。本发明涉及一种光固化方法,该方法包括在步骤1和步骤2之后执行的步骤1和步骤2,以及用于光固化方法的化合物和含有该化合物的光固化树脂组合物。步骤1:这是一个步骤,在该步骤中,在(A)具有通过光照生成自由基的羰基和通过光照脱羧生成羧基的化合物的存在下,(B)具有巯基或(甲基)丙烯基的硅烷偶联剂在酸性条件下与(C)水反应,以获得具有巯基或(甲基)丙烯基和至少一个硅醇基团的(D)硅烷化合物。步骤2:这是一个步骤,在该步骤中,在化合物(A)和(E)具有通过光照生成自由基的羰基和通过光照脱羧生成碱基的化合物的存在下,通过照射光线使化合物(A)和化合物(E)在反应系统中产生碱性条件,通过脱羧化合物(A)的羧基并从化合物(E)中生成碱基,并从化合物(A)和化合物(E)中生成自由基,从而生成包含从硅烷化合物(D)派生的构造单元的交联产物,如果需要,还可以从具有两个或更多可聚合不饱和基团的化合物(F)中派生。
