Abstract:
A nonaqueous liquid composition comprising at least one polymeric colorant containing composition and at least one viscosity reducing compound, wherein said viscosity reducing compound exhibits a dipole moment of between 1.0 and 5.0; wherein said at least one polymeric colorant is selected from the group consisting of any of the colorants defined within Formula (I)R{A[(B)nR1]m}xâ€ƒâ€ƒ(I) whereinR is an organic chromophore; A is a linking moiety in said chromophore selected from the group consisting of N, O, S, SO2N, and CO2; B is selected from the group of one or more alkyleneoxy constituents containing from 2 to 4 carbon atoms; n is an integer of from 2 to about 100; m is 1 when A is O, S, or CO2, and m is 2when A is N or SO2N; x is an integer of from 1 to about 5; and R1 is selected from the group consisting of H, C1-C4 alkyl, C1-C8 fatty ester, a C1-C20 alkenyl succinic anhydride moiety, and any mixtures thereof; and wherein said nonaqueous liquid composition exhibits a viscosity lower than the viscosity of said at least one polymeric colorant containing composition.
