Invention Patent "PYRROLIDONE DYE, MIXTURE OF TWO OR MORE PYRROLIDONE DYES, MIX OF TWO PYRROLIDONE DYES, MIXTURE OF DYES, PROCESS FOR COLORING SYNTHETIC TEXTILE MATERIALS OR THEIR FIBER MATERIALS, USE, SYNTHETIC TEXTILE ". A pyrrolidone dye of Formula (1): where D is a group of Formula (2): or a group of Formula (3): or a group of Formula (4): R1 is alkyl cycloalkyl, aryl, alkenyl or aralkyl, each of which can be optionally substituted; R 2 is alkyl of 7 to 20 optionally substituted carbon atoms; R ^ 1 ^ and R ^ 2 ^ together with a nitrogen atom in which they are attached form a pyrrolidine or piperidine ring; R ^ 3 ^ is alkyl, alkenyl or aralkyl, each of which can optionally be substituted, -SO ~ 2 ~ alkyl, -SO ~ 2 ~ aryl or -COR, where R is -H or alkyl, phenyl, cycloalkyl or aralkyl , each of them can be optionally replaced; or -H and R ^ 4 ^ is an electron withdrawal group; R 6 is alkyl of 1 to 6 optionally substituted carbon atoms; or R ^ 1 ^ and R ^ 6 ^ together with a nitrogen atom in which they are attached form a pyrrolidine or piperidine ring; R ^ 7 ^, R ^ 8 ^, R ^ 9 ^ and R ^ 10 ^ are each independently alkyl, cycloalkyl, aryl, alkenyl or aralkyl, each of which can optionally be substituted or -H; W is oxygen or sulfur; Z is a direct bond or N-R 4 11 is -H or optionally substituted alkyl or aryl; Ring A is unsubstituted apart from the group -NR ^ 1 ^ R ^ 2 ^ or is substituted by 1 to 4 other groups; Ring B is unsubstituted or substituted by 1 to 3 groups; provided that when D is a group of Formula (2) and R ^ 1 ^ and R ^ 2 ^ are both ally, that R ^ 4 ^ is not -CN or that when D is a group of Formula (3) that R ^ 1 ^ and R ^ 6 ^ are different and R ^ 1 ^ is not -C ~ 2 ~ H ~ 5 ~, -C ~ 3 ~ H ~ 7 ~ or -C ~ 4 ~ H ~ 9 ~, when R ^ 6 ^ is -C ~ 2 ~ H ~ 4 ~ phenyl, -C ~ 3 ~ H ~ 6 ~ phenyl and ethyl substituted by OH, -CN, -OCH ~ 3 ~, -OC ~ 2 ~ H ~ 4 ~ OC ~ 2 ~ H ~ 5 ~, -NHCOCH ~ 3 ~, -Ophenyl and -NHSO ~ 2 ~ CH ~ 3 ~ or that at least one of R ^ 1 ^ and R ^ 6 ^ is branched chain alkyl, except for 3- ( 4- (N-ethyl-N-ethoxyethoxyethyl amino) phenyl) -4-cyano-5-dicianomethylidene-2-oxo-2,5-dihydropyrrole and 3- (4- (N, N-di-n-octylamino) phenyl ) -4-cyano-5-dicyan methylidene-2-oxo-2,5-dihydropyrrole. Dyes and dye mixtures produce shades of blue to green in synthetic textile materials, such as polyester, which has a good development and good light and wet stability.
