    • Compounds of the general formula (I) or tautomeric forms thereof ##STR1## wherein Ar.sub.1 and Ar.sub.2 independently of one another denote radicals to complete optionally substituted carbocyclic aromatic rings, B denotes an optionally substituted alkylene group or a radical of the formula ##STR2## wherein r represents a number from 1 to 4, the ends of which are in each case bonded to an aromatic C atom of the two radicals Ar.sub.1 and Ar.sub.2, andX.sub.1 and X.sub.2 independently of one another represent a radical of the formulae chosen from the group consisting of ##STR3## these being in each case located in the ring such that the ##STR4## or the ##STR5## group is adjacent to the C--C double bond, wherein Y, Z, R.sub.a and R.sub.b have the meaning, given in the description, are outstandingly suitable for bulk dyeing of plastics.
    • 通式(I)或其互变异构形式的化合物,其中Ar 1和Ar 2彼此独立地表示完全任选取代的碳环芳环的基团,B表示任选取代的亚烷基或下式的基团其中r表示1 至4,其端部各自以键合到两个基团Ar1和Ar2的芳香族C原子,X1和X2彼此独立地表示选自以下各式的基团:在每种情况下, 位于环中,使得或该基团与CC双键相邻,其中Y,Z,Ra和Rb具有在说明书中给出的含义,非常适合于塑料的批量染色。
