Abstract
Disclosed are water-dispersible dye/resin compositions in solid, semi-solid or viscous liquid form, useful, for example, in the preparation of water-based heat transfer printing inks and aqueous dye dispersions for conventional dyeing. These compositions are solutions (this term as used herein encompasses true solution, colloidal dispersion and suspension) of disperse dyes in, for example, copolyesters of 5-sodiosulfoisophthalic acid optionally blended with certain aliphatic or cycloaliphatic dicarboxylic acids. Exemplary are solutions of dyes in the copolyesters of isophthalic acid, 5-20 mole % based on moles of glycol of 5-sodiosulfoisophthalic acid, and diethylene glycol. Aqueous dye dispersions can be made with these dye resin compositions without grinding of the dye beyond rough pulverization of the dye cake.
