Patent

CA 2445022

The present invention relates to pyridone dyes of formula (1), wherein R is a radical -(CR'H)n-W, R' is hydrogen, C1-C2alkyl or phenyl, Y is cyano, -CONH2 or -CH2SO3H, W is hydrogen, a radical -NR1R2 or a radical -OR3, R1 and R2 are each independently of the other hydrogen, unsubstituted or hydroxy- or phenyl- substituted C1-C6-alkyl, it being possible for the alkyl chain from C3 upwards to be interrupted by one or more oxygen atoms, or a radical of formula (3), (4) or (5), or R1 and R2 together with the nitrogen atom in -NR1R2 form a heterocyclic ring, R3 is hydrogen, unsubstituted or hydroxy-substituted C1- C6alkyl, phenyl or a radical of formula (6), R4 is alkyl or aryl, R5 and R6 are each independently of the other alkyl, aryl or heteroaryl, n is an integer from 2 to 6, and m is an integer from 1 to 6, a process for the preparation thereof and their use in the production of coloured plastics or polymeric colour particles.

L'invention porte sur des colorants de pyridone représentés par la formule (1) dans laquelle R est un radical (CR'H)¿n?-W, R' est hydrogène, C¿1?-C¿2 ?alkyl ou phényl,Y est cyano, -CONH¿2? ou -CH¿2?SO¿3?H, W est hydrogène, un radical -NR¿1?R¿2? ou un radical -OR¿3?, R¿1? et R¿2? sont chacun indépendants de l'autre hydrogène, un alkyl C¿1?-C¿6? substitué par phényl ou par hydroxy ou non substitué, la chaîne alkyle, en remontant depuis C¿3?, pouvant être interrompue par un ou plusieurs atomes d'oxygène, ou un radical représenté par la formule (3, 4, 5), ou R¿1? et R¿2? forment, avec l'atome de nitrogène dans NR¿1?R¿2?, un anneau hétérocyclique, R¿3? est hydrogène, un alkyl C¿1?-C¿6? substitué, un phényl ou un radical représenté par le formule (6), R¿4? est alkyle ou aryle, R¿5? et R¿6? sont chacun indépendants de l'autre alkyle, aryle ou hétéroaryle, n est un nombre entier compris entre 2 et 6, et m est un nombre entier compris entre 1 et 6. L'invention concerne aussi un procédé de préparation et d'utilisation correspondant dans la production de plastiques colorés ou de particules colorées polymériques.
