Abstract

Diphenylamines of the formula ##STR1## where the ring A can be benzo-fused, and PA1 D is aryl or a five-membered aromatic heterocyclyl which contains one to three hetero atoms selected from the group consisting of nitrogen, oxygen and sulfur, in the heterocyclic ring and can be fused to a benzene, thiophene, pyridine or pyrimidine ring, PA1 X is N.dbd.N or, if D is aryl, is alternatively CH.dbd.CH, or D--X together is 1,2,2-tricyanovinyl, PA1 R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are each hydrogen, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy or halogen, PA1 R.sup.5 is prop-1-en-3-yl, acryloyl or methacryloyl, PA1 R.sup.6 and R.sup.7 are each hydrogen, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy, halogen, prop-1-en-3-yl, acryloyl, methacryloyl or oxiranylmethoxy, and PA1 Y is C.sub.1 -C.sub.20 -alkylene, polymers derived from the compounds, and their use in non-linear optics.
