METHOD OF HARDENING COMPOSITIONS UTILIZING CATION PHOTOPOLYMERIZATION Russian patent published in 2002 - IPC

Abstract RU 2180669 C2

FIELD: polymerization processes. SUBSTANCE: when hardening cationically polymerizable monomers, composition, containing at least one cationically polymerizable monomer, at least one iodonium salt containing anion SbF₆, BF₆ or BF₆ as photoinitiator, one pigment, and at least one sensitizer, is applied onto substrate, the total is then irradiated by light with wavelength 200- 600 nm, and thermohardening proceeds at 100-250 C. EFFECT: reduced yellowing of hardened composition. 16 cl, 1 tbl, 5 ex
