Zusammenfassung:	본 발명은, UV 복사선으로 경화될 수 있는 수성 폴리우레탄 분산액에 관한 것이다. 상기 폴리우레탄은 방향족, 지환족 또는 지방족 다이아민 화합물로 쇄-연장되고 지방족 트라이아민 화합물과 가교-결합된다. 상기 폴리우레탄은 다양한 기재의 코팅에 유용한 분산액이다. The invention relates to aqueous polyurethane dispersions that are curable with UV radiation. The polyurethanes are chain-extended with aromatic, cycloaliphatic or aliphatic diamine compound and cross-linked with aliphatic triamine compound. The polyurethanes are useful dispersions for coating various substrates. The use of the invented dispersions results in high hardness, very good flexibility and good chemical resistance in both clear coats and pigmented coatings before and after UV curing combined with very good adhesion to different substrates.
