Abstract:
A colorant comprising a chromophore having two azo acetoacetanilide moieties and at least two pendant poly(oxyalkylene) chains conforming to the structure of Formula (I) wherein R is alkyl, phenyl, polyphenyl, substituted phenyl, or substituted polyphenyl; E is hydrogen, alkyl, halogen, alkoxy, or phenyl; a is 0, 1, or 2, wherein if a is 0 then A is phenyl, polyphenyl, substituted polyphenyl, or substituted phenyl, if a is 1, then A is O, SO2N, methylene, S, N(Râ€²) or a moiety of Structure (II) wherein Râ€² is alkyl or hydrogen, and if a is 2, then A is O, SO2, methylene, S, N(Râ€²), wherein Râ€² is alkyl of hydrogen; B is Râ€³(gly) w[(EO)x(PO)y(EO)zEG]nâ€³ wherein EG is H or a moiety of Structure (III) wherein R4 is C1-C12 alkyl or phenyl; all wherein gly is glycidol, EO is ethylene oxide, and PO is selected from the group consisting of propylene oxide, butylene oxide, and any mixtures or combinations thereof, n is 1 to 4, and wherein Râ€³ is O, N, SO2N, methylene, S, N(R5), wherein R5 is alkyl; wherein if Râ€³ is O or SO2N then w=0 or 1, x=0-30, y=0-30, and z=0-30, wherein w+x+y+z>2, and if Râ€³ is other than O or SO2N, then w=0-2, x=0-30, y=0-30, and z=0-30, wherein w+x+y+z>2; and wherein Râ€²â€³ is halogen, hydrogen, alkyl, alkoxy, or B.
