PHOTOPOLYMERISIERBARES GEMISCH UND DIESES ENTHALTENDES PHOTOPOLYMERISIERBARES AUFZEICHNUNGSMATERIAL.

摘要

Photopolymerisable mixt. is based on (a) a polymeric binder, (b) a polymerisable cpd. with terminal ethylenically unsatd. double bond(s), and a b.pt. above 100 deg.C at normal pressure and (c) a tricyclic N-heterocyclic cpd. as photoinitiator. The novelty is that (c) is a 2,3-dihydro-1H-cyclopenta(b)-quinoline of formula (I); (R1 = a (substd.)m-valent carbo- or heterocyclic aromatic gp.; R 2 = H, alkyl, aryl, aralkyl or aralkylene; R3 and R4 independently = H, halogen, alkyl or alkoxt; n = 0 or 1; m = 1 or 2).
