Compounds of formula (I) wherein R1 is hydrogen, hydroxy, halogen, nitro, cyano, amino, carboxy, carboxylic ester, sulfo, sulfonic ester, carboxylic amide, sulfonic amide, alkylthio, arylthio, alkoxy or aryloxy, R'1 is hydrogen, hydroxy, halogen, nitro, cyano, amino, carboxy, carboxylic ester, sulfo, sulfonic ester, carboxylic amide, sulfonic arnide, alkylthio, arylthio, alkoxy or aryloxy, X is -O-, -S-, -NH- or -N(alkyl)-, X' is -0-, -S-, -NH- or - N(alkyl)-, Y is hydrogen or carboxylic ester, Y' is hydrogen or carboxylic ester, Z is =C- or =N-, Z' is =C- or =N-, x is 0 or 1, when Z is =N-, then x is 0, y is 0 or 1, when Z' is =N-, then y is 0, A is a conjugated linking bridge of the formulae (II), (III), (IV), (V), or (VI), wherein n is 0, 1, 2 or 3, m is 0, 1, 2 or 3, B is a phenyl ring, T is =C(R3)- or =N-, wherein R3 is hydrogen, C1-C12alkyl or CN, W is a heterocyclic, or linear or polycondensed aromatic group which is unsubstituted or substituted by alkyl, halogen, hydroxy, alkoxy, alkylthio or amino, G is -CH= or -N=, and R2 is hydrogen, alkyl, halogen, hydroxy, alkoxy, alkylthio or amino, their preparation and their use in the production of coloured plastics or polymeric color particles.

La présente invention se rapporte à des composés représentés par la formule (I) dans laquelle R¿1? est hydrogène, hydroxy, halogène, nitro, cyano, amino, carboxy, ester carboxylique, sulfo, ester sulfonique, amide carboxylique, amide sulfonique, alkylthio, arylthio, alcoxy ou aryloxy, R'¿1? est hydrogène, hydroxy, halogène, nitro, cyano, amino, carboxy, ester carboxylique, sulfo, ester sulfonique, amide carboxylique, amide sulfonique, alkylthio, arylthio, alcoxy ou aryloxy, X est -O-, -S-, -NH- ou -N(alkyl)-, X' est -O-, -S-, -NH- ou -N(alkyl)-, Y est hydrogène ou ester carboxylique, Y' est hydrogène ou ester carboxylique, Z est =C- ou =N-, Z' est =C- ou =N-, x est 0 ou 1, lorsque Z est =N-, alors x est 0, y est 0 ou 1, lorsque Z' est =N-, alors y est 0, A est un pont de liaison conjugué représenté par les formules (II), (III), (IV), (V), (VI), dans lesquelles n est 0, 1, 2 ou 3, m est 0, 1, 2 ou 3, B est un noyau phényle, T est =C(R¿3?)- ou =N-, où R¿3? est hydrogène, alkyle C¿1?-C¿12? ou CN, W est un groupe aromatique hétérocyclique ou linéaire ou polycondensé qui est non substitué ou substitué par alkyle, halogène, hydroxy, alcoxy, alkylthio ou amino, G est -CH= ou -N=, et R¿2? est hydrogène, alkyle, halogène, hydroxy, alcoxy, alkylthio ou amino. L'invention se rapporte également à un procédé de préparation de ces composés ainsi qu'à leur utilisation pour la production de plastiques colorés ou de particules colorées polymères.
