摘要

The object of the invention is new general formula diaryloiodine salts (1),where the constituents R11-R15 independently denote: H, CN, group CnH2n+1, where n denotes the total number from 1 to 12, in the form of simple alkyl or branched as CH3, C(CH3)3 CH(CH3)2or parent OCnH2n+1, where n denotes the total number from 1 to 12, such as OCH3; E- means an anion selected from a group comprising PF6-,SbF6,BF4,CF3SO3-,TsO,B(C6F5)4-,B(C6H5)4-,[Al(OC(CF3)3)4]-;-X is the residual 2-cyano-2-phenylphenyl with a general formula (2A) associated with the iodine atom by any of the carbon atoms in positions 2-6 corresponding to the position of the constituents R1 -R5, respectively, in which formula R1 -R5, unless the corresponding carbon atom in 2-6 does not bind to the iodine atom, they independently refer to `H'or `OCnH2n+1in which n means the total number from 1 to 12, such as `OCH3'; the R6-R10 constituents independently refer to `H', CN or any two adjacent constituents of R6-R10 form an unsaturated six-month ring,which, together with the ring to which it is attached, are the constituents R6-R10, forms an oil group. The invention also covers the production and use of new diaryloidone salts as well as new intermediate compounds. stlibene used in the production and use of new diaryloidone salts. The invented diaryloidone salts can be used as photoinitiators for cationic and root photopolymerisation.
