    • A pyrrolidone dye of Formula (1), wherein: D is a group of Formula (2), or a group of Formula (3), or a group of Formula (4), R is alkyl, cycloalkyl, aryl, alkenyl or aralkyl each of which may be optionally substituted; R is optionally substituted C7-20-alkyl; or R and R together with the nitrogen atom to which they are attached form a pyrrolidino or piperidino ring; R is alkyl, alkenyl or aralkyl each of which may be optionally substituted or -COR in which R is -H or alkyl, phenyl, cycloalkyl or aralkyl each of which may be optionally substituted or -H; and R is an electron withdrawing group; R is optionally substituted C1-6-alkyl; or R and R together with the nitrogen atom to which they are attached form a piperidino or pyrrolidino ring; R , R , R and R each independently is alkyl, cycloalkyl, aryl, alkenyl or aralkyl each of which may be optionally substituted or -H; W is oxygen or sulphur; Z is a direct link or N-R in which R is -H or optionally substituted alkyl; Ring A is unsubstituted apart from the -NR R group or is substituted by from 1 to 4 further groups; Ring B is unsubstituted or substituted by from 1 to 3 groups; provided that when D is a group of Formula (2) and R and R are both allyl that R is not -CN or that when D is a group of Formula (3) that R and R are different and R is not -C2H5, -C3H7 or -C4H9 when R is -C2H4phenyl, -C3H6phenyl and ethyl substituted by -OH, -CN, -OCH3, -NHCOCH3, -Ophenyl and -NHSO2CH3 or that at least one of R and R is branched chain alkyl except for 3-(4-(N-ethyl-N-ethoxyethoxyethylamino)phenyl)-4-cyano-5-dicyanomethylidene-2-oxo-2,5-dihydropyrrole and 3-(4-(N,N-di-n-octylamino)phenyl)-4-cyano-5-dicyanomethylidene-2-oxo-2,5-dihydropyrrole. The dyes and dye mixtures produce blue to green shades on synthetic textile materials such as polyester which have good build up and good light- and wet-fastness.
    • 式(1)的吡咯烷酮染料,其中:D是式(2)的基团,或式(3)的基团或式(4)的基团,R 1是烷基,环烷基,芳基, 烯基或芳烷基,其各自可以任选被取代; R 2是任选取代的C 3-20 - 烷基; 或R 1和R 2与它们所连接的氮原子一起形成吡咯烷子基或哌啶子基环; R 3是烷基,烯基或芳烷基,其各自可以是任选取代的或-COR,其中R是-H或烷基,苯基,环烷基或芳烷基,其各自可以是任选取代的或-H; R 4为吸电子基团; R 6是任选取代的C 1-6 - 烷基; 或R 1和R 6与它们所连接的氮原子一起形成哌啶子基或吡咯烷子基环; R 7,R 8,R 9和R 10各自独立地是烷基,环烷基,芳基,烯基或芳烷基,其各自可以是任选取代的或-H; W是氧或硫; Z是直链或N-R 11,其中R 11是-H或任选取代的烷基; 除了-NR 1 R 2基团之外,环A是未取代的或被其它1至4个其它基团取代; 环B是未取代的或被1至3个基团取代; 条件是当D是式(2)的基团且R 1和R 2都是R 4不是-CN的烯丙基时,或当D是式(3)的基团时,R 1 >和R 6不同,当R 6为-C 2 H 4苯基,-C 3 H 6苯基和被-OH,-CN,-OCH 3,-NHCOCH 3取代的乙基时,R 1不为-C 2 H 5,-C 3 H 7或-C 4 H 9, - 苯基和-NHSO 2 CH 3,或者R 1和R 6中的至少一个是支链烷基,除了3-(4-(N-乙基-N-乙氧基乙氧基乙基氨基)苯基)-4-氰基-5-二氰基亚甲基 -2-氧代-2,5-二氢吡咯和3-(4-(N,N-二正辛基氨基)苯基)-4-氰基-5-二氰基亚甲基-2-氧代-2,5-二氢吡咯。 染料和染料混合物在合成纺织材料如聚酯上产生蓝色至绿色的色调,其具有良好的聚集性和良好的耐光牢度和耐湿牢度。
