Abstract

The application concerns new iodonium salts, a method for producing new iodonium salts, applications of new iodonium salts, new photocurable composites intended for dental fillings, a method for producing new photocurable composites intended for dental fillings, new two-component photoinitiating systems, new benzene derivatives and applications of benzene derivatives. The new iodonium salts according to the invention are defined by the general formula (1), wherein E -denotes a hexafluorophosphate or tosyl anion, and X denotes a substituent of general formula (2A) bonded to the iodine atom via a carbon atom in position 2 or 5, corresponding to the position of substituent R1 or R4, respectively, in which formula (2A) substituents R1 - R4, unless the carbon atom in position 2 or 5 corresponding to substituent R1 or R4 forms a bond with the iodine atom, independently of each other denote a hydrogen atom or a methoxy group, substituent R denotes a naphthyl group, a dibenzo[b,d]furanyl group, an anthracyl group or a group of general formula (5), in which R' denotes —H, -CN, -SO2CH3.
