PROBLEM TO BE SOLVED: To provide a polyurethane material useful for a coating composition which can or may be applied to a substrate by an electrodeposition coating method and a non-electrodeposition coating method. SOLUTION: There are provided a polyurethane material, a coating prepared therefrom and a method for producing them. The polyurethane material can be formed from components including at least one polyisocyanate, at least one active hydrogen-containing material, at least one material having at least one primary or secondary amino group and at least one hydroxyl group, and at least one acid functional material or an anhydride thereof having a functional group reactive with an isocyanate group or a hydroxyl group that is other components forming the polyurethane material. When being incorporated into a coating composition, the polyurethane can provide improved physical properties (for example, chip resistance). COPYRIGHT: (C)2007,JPO&INPIT
