Beschreibung
Zusammenfassung:	The present invention relates to an aqueous dispersion polyurethane urea resin composition for synthetic leather and a manufacturing method thereof. More specifically, the present invention provides the aqueous dispersion polyurethane urea resin composition for synthetic leather which contains an ionic compound having a sulfonic acid group and does not contain a neutralizing agent, and has excellent resin stability, heat resistance and aesthetics, and a manufacturing method thereof. In addition, the aqueous dispersion polyurethane urea resin composition for synthetic leather according to the present invention can be applied to various uses by controlling the polyurethane urea particle size to a desired size by controlling the content of the ionic compound having the sulfonic acid group. 본 발명은 합성피혁용 수분산 폴리우레탄우레아 수지 조성물 및 그 제조방법에 관한 것으로서, 보다 상세하게는 설폰산기를 가지는 이온성 화합물을 포함하고 중화제를 비포함함으로써, 수지안정성, 내열성 및 심미성이 우수한 합성피혁용 수분산 폴리우레탄우레아 수지 조성물 및 그 제조방법을 제공한다. 또한, 본 발명에 따른 합성피혁용 수분산 폴리우레탄우레아 수지 조성물은 설폰산기를 가지는 이온성 화합물의 함량을 조절함으로써 폴리우레탄우레아 입자 크기를 원하는 크기로 제어하여 다양한 용도로 적용될 수 있다.
