ULTRAVIOLET-ABSORBING RESIN, AQUEOUS RESIN EMULSION, RESIN COMPOSITION, AQUEOUS RESIN EMULSION COMPOSITION AND ITS USE, AND AQUEOUS POLYURETHANE EMULSION
Document Type and Number:
WIPO Patent Application WO/2002/032981
Kind Code:
A1
Abstract:
An aqueous emulsion of an ultraviolet-absorbing resin prepared by reacting a polyester polyol (A) having ultraviolet-absorbing groups with a compound (C) bearing an ionic and/or nonionic surface active group, an organic polyisocyanate (D), and, if necessary, a polyol (B) optionally in an organic solvent (s) to obtain an ultraviolet-absorbing resin (i) and neutralizing a solution of the resin (i) with a neutralizing agent (E) is excellent in compatibility, light resistance, bleedout resistance, alkali resistance and solvent resistance and useful in the coating of artificial leather, plastics, woody materials and so on. Artificial leather made from an aqueous polyurethane emulsion constituted of a polyester diol (VIIIA) comprising one diol selected from among 2-n-butyl-2 -ethyl-1,3-propanediol, 2,2-diethyl-1,3-propanediol and 2,4-diethyl-1,5-pentanediol, e-caprolactone, and adipic acid as constituent units, a chain-lengthening agent (VIIIB), a compound (C) bearing an ionic and/or nonionic surface active group, an organic polyisocyanate (D), and a neutralizing agent (E) is excellent in softness, light resistance, resistance to hydrolysis, and heat resistance.
