Quaternary ammonium salts for photocurable vesicular compositions, their preparation and photocurable vesicular compositions containing them

摘要

Quaternary ammonium salts having the following formula are disclosed.;Here, R_OneCH₃(CH₂)_nCH₂Or CH₃(CH₂)_nCH₂C₆H₄(Where n is an integer of 1-16). R₂And R₃Are both CH₂= C (CH₃) COOCH₂CH (OH) CH₂Or CH₂= CHCOOCH₂CH (OH) CH₂, Or either one of CH₂= C (CH₃) COOCH₂CH (OH) CH₂Or CH₂= CHCOOCH₂CH (OH) CH₂And the other is H. R₄Is H, CH₃, CH₃CH₂Or CH₃CH₂CH₂to be. X is CH₃OSO₃, CH₃CH₂OSO₃, CH₃COO, CF₃COO, CH₃(CH₂)_nCOO (wherein n is an integer of 1-16), CH₃(CH₂)₇CH = CH (CH₂)₇COO, C₆H₅COO, C₆H₅CH (OH) COO, HOOCCH₂CH (OH) COO, Cl or Br. The photocurable vesicle composition containing a quaternary ammonium salt having the above formula can form a coating film having excellent photocurability, surface hardness, adhesiveness, transparency and long-term durability persistence.
