Aliphatic bridged chromogenic bisquinazolines substituted with phenylamine or phenyl-containing heterobicyclic radicals

Claim 1

A chromogenic bisquinazoline of the formula ##STR39## wherein the ring A is unsubstituted or substituted by a group selected from nitro, halogen, lower alkyl, phenyl, benzyl, lower alkoxy and lower alkoxycarbonyl; Q is an alkylene or heteroalkylene radical having 2 to 8 carbon atoms, a radical of a polyalkylene glycol having a molecular weight in the range of from 28 to 450, or a radical of the formula ##STR40## wherein m is 1 to 9 and s is 1 to 5, or is a cycloaliphatic or araliphatic radical having not more than 10 carbon atoms; Y is the radical of the formula ##STR41## wherein X 1 and X 2 , each independently of the other, is hydrogen, alkyl of not more than 12 carbon atoms, unsubstituted or substituted by a group selected from halogen, hydroxy, cyano and lower alkoxy, or are cycloalkyl having 5 to 10 carbon atoms, phenyl, benzyl, or phenyl or benzyl, each substituted by a group selected from halogen, nitro, cyano, lower alkyl, lower alkoxy and lower alkoxycarbonyl; or X 1 and X 2 , together with the nitrogen atom to which they are attached, are a 5- or 6-member N-heterocyclic radical or a heterocyclic radical which has, in addition to nitrogen, at least one additional hetero atom selected from the group consisting of nitrogen, oxygen and sulfur; X 3 is hydrogen, halogen, lower alkyl, lower alkoxy or lower alkoxycarbonyl, and Z is hydrogen or alkyl of not more than 8 carbon atoms, unsubstituted or substituted by a member selected from the group consisting of halogen, cyano and lower alkoxy, and the benzene ring B is unsubstituted or substituted by cyano, halogen, lower alkyl or lower alkoxy, and the ring D is a hydrogenated 5- or 6-membered N-heterocyclic ring system which is unsubstituted or C-substituted by one or more of the same or different members selected from the group consisting of halogen, cyano, hydroxyl, lower alkyl, lower alkoxy, C 5 -C 6 cycloalkyl, benzyl and C 3 -C 6 alkylene.
