A water-dispersable polycarbonate polyurethane resinncomposition obtained by creating an emulsified dispersionnof a urethane prepolymer with isocyanate groups at thenends in water in the presence of an emulsifying agent ifnnecessary, and then extending the ends with a polyaminencompound containing 2 or more amino groups and/or iminongroups in the molecule, wherein the polyol component usednfor production of the urethane prepolymer contains anpolycarbonate polyol as a portion thereof, and thenpolyisocyanate component comprises at least 2npolyisocyanates. The composition gives a soft andnresilient hand quality to treated fabrics, can be stablynand reasonably produced, has excellent film formabilitynin a suitable state of aqueous dispersion, and also hasnexcellent water resistance, light fastness, heatnresistance, oil resistance and solvent resistance. |
