Compounds of the general formula (I) or tautomeric forms thereof (see formula I) where Ar1 and Ar2 are independently radicals needed to complete optionally substituted carbocyclic aromatics, B is a radical of the formula -T1-W-T2-, where T1 and T2 are independently O or S and W ~is alkylene, especially C1-C6-alkylene, C6-Cl0-arylene, especially phenylene or cycloalkylene, which are each optionally substituted or is~ the radical of the formula (a) Image where the phenyl rings are optionally substituted and A ~is a radical of the formula O, S, SO, SO2 or CO, optionally substituted alkylene, or optionally substituted cycloalkylene, said alkylene or cycloalkylene being attached to the adjacent phenyl rings itself or else via its substitutents, or W ~is a radical of the formulae ~(CH2)s~O-(CH2)t~, ~(CH2)~S~(CH2)t~, Image where s and t are independently from 1 to 6, the ends of the divalent radical B each being attached to an aromatic carbon atom of the two radicals Ar1 and Ar2, and X1 and X2 are independently a radical of the formulae selected from the group consisting of Image these each being located in the ring in such a way that the Image is adjacent to the C-C double bond, where Y ~is the radical of an optionally substituted benzene or naphthalene ring, Z ~is optionally substituted ortho-phenylene, ortho-naphthylene, peri-(1,8)- naphthylene or arylene composed of more than two fused-together benzene rings, the aryl radicals which have more than two fused-together benzene rings being bridged ortho or in a manner corresponding to a peri position in naphthalene, R a is H or OH, and R b is H or halogen, especially F, Br or Cl.
