MOLECULAR-COMPLEX COMPOUND, PHOTOPOLYMERIZING COMPOSITION AND PHOTOPOLYMERIZATION PROCESS Russian patent published in 2002 - IPC

FIELD: polymerization processes. SUBSTANCE: molecular-complex compound consists of (i) mono- or bis-acylphosphine oxide of formula I: (I), in which R₁ and R₂, independently from each other, denote C1-C12-alkyl, phenyl optionally 1-4-fold substituted by C1-C8-alkyl and/or C1- C8-alkoxyl, or COR₃ group; R₃ denotes phenyl optionally 1-4-fold substituted by C1-C8-alkyl and/or C1-C8-alkoxyl; and (ii) alpha- hydroxyketone compound of formula II: R₁₁ (II), in which R₁₂ and R₁₁, independently from each other, denote C1-C6- alkyl or R₁₂ and R₁₃, together with carbon atom to which they are linked, form cyclohexyl ring; R₁₄ represents hydroxy; and hydrogen. Proposed compound can be used photoinitiator. Invention also provides photopolymerizing composition, composition for manufacture of varnishes, printing inks, forming plates, dental pastes, resist materials as well as video recording material, in particular for bolographic imaging. EFFECT: extended choice of photopolymerizing materials. 12 cl, 1 tbl, 8 ex
