The present invention is directed to sulfonium salt-containing compounds represented by a following general formula;
wherein R1 is alkyl containing from 1 to 18 carbon atoms, hydroxy, alkoxy containing from 1 to 18 carbon atoms, alkylcarbonyloxy containing from 1 to 18 carbon atoms or halogen, n is any of 0, 1, 2 or 3, however, each of R1 may be different from the others when n is 2 or more, R2 is alkyl containing from 1 to 6 carbon atoms, R3 and R4 are each independently hydrogen or alkyl containing from 1 to 6 carbon atoms, R5 and R6 are each independently hydrogen, alkyl containing from 1 to 6 carbon atoms, hydroxy, alkoxy containing from 1 to 6 carbon atoms, alkylcarbonyloxy containing from 1 to 18 carbon atoms or aromatic carbonyloxy, and R7 is alkyl containing from 4 to 20 carbon atoms or a group represented by a following formula;
wherein R8 is alkyl containing from 1 to 18 carbon atoms, hydroxy, alkoxy containing from 1 to 18 carbon atoms, alkylcarbonyloxy containing from 1 to 18 carbon atoms, aromatic carbonyloxy or halogen, m is any of 0, 1, 2 or 3, however, each of R8 may be different from the others if m is 2 or more, and X is non-nucleophilic anion residue, and hardening compositions comprising said sulfonium salt-containing compounds.
In particular, a hardening composition comprising the sulfonium salt-containing compound represented by the general formula [I] shown above, a sensitizer and a cationic polymerizable compound can harden in a short time under either heating or irradiation of light or the like, and therefore, said hardening composition can be suitably used for coating materials, adhesives, photoresists, etc.
本发明涉及由以下通式表示的含锍盐化合物;
其中 R1 是含 1 至 18 个碳原子的烷基、羟基、含 1 至 18 个碳原子的烷氧基、含 1 至 18 个碳原子的烷基羰氧基或卤素,n 是 0、1、2 或 3 中的任一个,然而,当 n 为 2 或更多时,每个 R1 可与其它的不同,R2 是含 1 至 6 个碳原子的烷基、R3 和 R4 各自独立地为氢或含 1 至 6 个碳原子的烷基,R5 和 R6 各自独立地为氢、含 1 至 6 个碳原子的烷基、羟基、含 1 至 6 个碳原子的烷氧基、含 1 至 18 个碳原子的烷基羰氧基或芳香族羰氧基,以及 R7 为含 4 至 20 个碳原子的烷基或下式所代表的基团;
其中 R8 是含 1 至 18 个碳原子的烷基、羟基、含 1 至 18 个碳原子的烷氧基、含 1 至 18 个碳原子的烷基羰氧基、芳香族羰氧基或卤素,m 是 0、1、2 或 3 中的任一个,但是,如果 m 是 2 或更多,则每个 R8 可与其它的不同,X 是非亲核阴离子残基,以及包含所述含锍盐化合物的硬化组合物。
特别是,由上述通式[I]表示的含锍盐化合物、敏化剂和阳离子可聚合化合物组成的硬化组合物在加热或光照射等条件下可在短时间内硬化,因此,所述硬化组合物可适用于涂层材料、粘合剂、光刻胶等。
