ABSTRACT:
A water-dispersible polyester composition for an image recording medium, comprising (1) a polyester having a glass transition temperature of not less than 40.degree.C., a specific gravity of not less than 1.25, a value of SP of 9.5-12.0, and at least one kind of hydrophilic polar group, and which is insoluble in methyl ethyl ketone, toluene, and a mixed solvent thereof, wherein 65% by mole or more of a glycol component constituting the polyester is ethylene glycol, in a proportion of 5-50% by weight, (2) an organic compound compatible with water in a proportion of 0-20% by weight, and (3) water in a proportion of 30-95% by weight all percentages by weight being based upon the total weight of said composition containing components (1), (2) and (3). When used for an image recording layer of an image recording medium, the composition of the invention is conducive to the durability of the recorded images excellent in heat resistance, resistance to plasticizer, resistance to fingerprint, and solvent resistance.
