Water-dispersible polyurethane-urea resin composition for synthetic leather and preparing method thereof

Abstract

The present disclosure relates to a polyurethane-urea resin composition for synthetic leather and a method of preparing the polyurethane-urea resin composition, the polyurethane-urea resin composition having excellent resin stability, heat resistance and aesthetic properties by including an ionic compound containing a sulfonic acid group, and by not including a neutralizer. In addition, the polyurethane-urea resin composition for synthetic leather may be applicable for various purposes by controlling a polyurethane-urea particle size to a desired size by controlling a content of the ionic compound containing a sulfonic acid group.

Dependencies are inferred from the claim text.
