Abstract:
A pigment of the formula (I) ##STR72##wherein R.sub.1 and R.sub.2 are independently the atoms necessary to complete the formation of a substituted or unsubstituted aromatic or aliphatic carbocyclic or heterocyclic ring system, the radicals R.sub.3 and R.sub.4, independently of each other, are hydrogen or a group of the formulae (II), (III) or (IV) ##STR73##whereby in the formulae (II), (III) and (IV)m, n and p, independently of each other, are zero or 1;X C.sub.1-14 -alkylene or C.sub.2-8 -alkenylene;Y a group --V--(CH.sub.2).sub.q --;Z a group --V--(CH.sub.2).sub.r --;V C.sub.3-6 -cycloalkylene;q a number of 1 to 6; andr a number of zero to 6,R.sub.8 and R.sub.9 independently of each other, signify hydrogen, C.sub.1-6 -alkyl, C.sub.1-4 -alkoxy, halogen, CN, NO.sub.2, unsubstituted phenyl or phenoxy, phenyl or phenoxy substituted by C.sub.1-4 -alkyl, C.sub.1-4 -alkoxy or halogen;Q hydrogen, CN, Si(R.sub.8).sub.3, a group C(R.sub.12)(R.sub.13)(R.sub.14), in which R.sub.12, R.sub.13 and R.sub.14 are halogen; a group ##STR74##in which R.sub.8 and R.sub.9 have the above meaning; a group SO.sub.2 --R.sub.15 or SR.sub.15, in which R.sub.15 is C.sub.1-4 -alkyl ; a group CH(R.sub.16).sub.2, in which R.sub.16 is unsubstituted phenyl or phenyl substituted by C.sub.1-4 -alkyl, C.sub.1-4 -alkoxy or halogen; or a group of the formula ##STR75##R.sub.10 and R.sub.11 independently of each other, signify hydrogen, C.sub.1-18 -alkyl, a group ##STR76##in which X, Y, R.sub.8, R.sub.9, m and n have the above meaning, orR.sub.10 and R.sub.11, together represent a chain necessary to complete formation of a pyrrolidine, piperidine or mornholine ring system,provided that, if R.sub.3 and/or R.sub.4 are a group of the formula (III), Q is hydrogen and n is zero, m must be 1 and X is a C.sub.2-14 -alkylene- or C.sub.2-8 -alkenylene group which is branched at the carbon atom bound to oxygen, and if both R.sub.3 and R.sub.4 are hydrogen, R.sub.1 and R.sub.2 cannot be identical.
