Compounds of formula (I) [in which: R1 represents a direct bond, an oxygen atom, a group >CH2, a sulphur atom, a group >C=O, a group -(CH2)2- or a group of formula -N-Ra, where Ra is hydrogen or an alkyl; R4, R5, R6 and R7 are each hydrogen or various groups or atoms; R8, R9, R10 and R11 are each hydrogen, hydroxy, or alkyl; or R9 and R11 form a fused ring system with the benzene rings to which they are attached; R12 is a direct bond, oxygen atom or methylene; and X is an anion; and esters thereof] are useful as cationic photoinitiators, especially for use in surface coating applications, such as printing inks and varnishes, and which are intended to be cured by polymerisation initiated by radiation.
化合物的化学式(I)[其中:R1代表直接键,氧原子,基团>CH2,硫原子,基团>C=O,基团-(CH2)2-或化学式-N-Ra的基团,其中Ra是氢或烷基;R4、R5、R6和R7分别是氢或不同的基团或原子;R8、R9、R10和R11分别是氢、羟基或烷基;或者R9和R11与它们连接的苯环形成融合环系统;R12是直接键,氧原子或亚甲基;X是阴离子;以及它们的酯]可用作阳离子光引发剂,特别适用于表面涂层应用,如印刷油墨和清漆,旨在通过辐射引发的聚合物化来固化。
