| abstract |
This composition comprises (a) a polymerizable compound containing at least one double bond of ethylenic unsaturation, (b) at least one photo-polymerization initiator chosen from the ketal derivatives of formula [1], (c) at least one initiator photo-polymerization selected from thioxanthone derivatives of formula [2], (d) a reducing agent and (e) a filler. In the formula [1], X = H, Cl, alkyl, alkoxy; A = six-membered aromatic group; R = alkyl, aralkyl, (CnH2nO) m R '(n = integer from 2 to 5 m = integer from 1 to 5; R' = alkyl). In formula [2], X => S,> SO and> SO2; R, R '= optionally substituted alkyl, alkoxy, halogen, nitro, divalent unsaturated group forming a condensation ring structure; n and m = 0 or number from 1 to 4.
