Photoinitiating polymerization composition

Abstract

The subject of the application is a photoinitiating polymerization composition intended for use in dentistry, stereolithography printing, and the production of varnishes and self-adhesive adhesives. The composition contains triacrylate, a squaryl dye derivative of benzothiazol as a sensitizer (at a concentration of 0.5 - 5 x 10 -3 M) of the formula I, wherein the substituent R is independently of each other a hydrogen atom (H) or a methyl group (CH3) and as a co-initiator a diphenyliodonium salt of the formula II, in the amount of 0.32 - 3.17 mg (at a concentration of 0.5 - 5 x 10 -3 M), where X is a chlorine atom (Cl), R1, R2 are hydrogen atoms (H), 0.53 - 5.27 mg (at a concentration of 0.5 - 5 x 10 -3 M), wherein X is a para-toluenesulfonic acid group, R1, R2 are methoxy (CH3O) and nitro (NO2) groups, respectively, 0.56 - 5.61 mg (at a concentration of 0.5 - 5 x 10 -3 M), where X is a para-toluenesulfonic acid group, R1, R2 are a bromine atom and a methoxy group (CH3O), respectively.
