摘要：
Polyester fabrics and rigid plastic substrates are respectively dyed and colored with a series of compounds of the formula:
WHEREIN R is hydrogen, chlorine, bromine, nitro, or acetamido; A is lower alkyl, benzyl or cyano(lower alkyl); EACH OF X and Y is independently cyano, lower carbalkoxyl
OR R1-SO2, R1 being a member selected from the group consisting of lower alkyl, chloro(lower alkyl), bromo(lower alkyl), cyano(lower alkyl), phenyl, (lower alkyl) phenyl, chlorophenyl, bromophenyl, nitrophenyl, and cyanophenyl; and X and Y taken together form a ring containing 5 or 6 ring atoms. The above compounds are useful as dyes and, according to a preferred embodiment, colorants for rigid plastic substrates.
WHEREIN W is lower alkylene or p-xylylene; EACH OF X and Y is independently cyano, lower carbalkoxyl,
OR R1-SO2, R1 being a member selected from the group consisting of lower alkyl, chloro(lower alkyl), bromo(lower alkyl), cyano(lower alkyl), phenyl, (lower alkyl) phenyl, chlorophenyl, bromophenyl, nitrophenyl, cyanophenyl; and X and Y taken together with form a ring containing 5 or 6 ring carbon atoms. In addition a further series of compounds is provided of the formula:
