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.
本发明的目的是提供一种光固化方法,该方法可以快速有效地获得交联产品(树脂)、光固化方法中使用的化合物以及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,它包括步骤 1 和在步骤 1 之后进行的步骤 2、光固化方法中使用的化合物以及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(A)具有通过光照射产生自由基的羰基和通过光照射脱羧的羧基的化合物存在下,(B)具有巯基或(甲基)丙烯酰基的硅烷偶联剂与(C)水在酸性条件下反应,得到(D)具有巯基或(甲基)丙烯酰基和至少一个硅烷醇基的硅烷化合物。
步骤 2:这一步是在化合物(A)和(E)存在的情况下,化合物(A)和化合物(E)具有通过光照射产生自由基的羰基和通过光照射脱羧产生碱的基团,用光照射化合物(A)和化合物(E),通过脱羧化合物(A)的羧基和从化合物(E)中产生碱,在反应体系中形成碱性条件、并从化合物(A)和化合物(E)中生成自由基,以生成含有由硅烷化合物(D)和(如有必要)由具有两个或两个以上可聚合的不饱和基团的化合物(F)衍生出的结构单元的交联产物。
