Abstract
The present invention relates to a process for bulk coloration of high molecular weight organic material, which comprises the use of a compound of the formula (I) ##STR1## in which Q is O or S, and X is C(R.sub.3) or N, PA0 R.sub.1, R.sub.2 and R.sub.3 independently of one another are hydrogen, halogen chosen from the group consisting of chlorine, bromine and fluorine, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, hydroxyl, cyano, nitro, amino, morpholino, ##STR2## in which A.sub.1 and A.sub.2 independently of one another are unsubstituted or substituted C.sub.6 -C.sub.12 aryl or C.sub.3 -C.sub.12 heteroaryl, which contains, in the ring system, 1 to 3 hetero atoms chosen from the group consisting of N, O and S, and E.sub.1 is ##STR3## or R.sub.1 and R.sub.2 together, or R.sub.1 and R.sub.3 together, are a radical A.sub.3, PA1 which A.sub.3 is unsubstituted or substituted C.sub.4 -C.sub.8 alkenylene or C.sub.8 -C.sub.12 arylene. Individual novel compounds of the formula (I) are claimed themselves.
