PHOTO-SETTING LIQUID FOR OPTICAL THREE-DIMENSIONAL SHAPING AND PHOTO-SETTING COMPOSITION FOR OPTICAL THREE-DIMENSIONAL SHAPING CONTAINING THE SAME

摘要

PURPOSE: To obtain a three-dimensional shaped article excellent in mechanical physical properties, thermal physical properties and shape accuracy by using a photo-setting liquid for optical three-dimensional shaping consisting of specific unsaturated ester urethane and a vinyl monomer. CONSTITUTION: A photo-setting liquid for optical three-dimensional shaping consists of unsaturated ester urethane represented by formula I and a vinyl monomer and is characterized by that a wt. ratio of unsaturated ester urethane/ vinyl monomer is 100/25-100/150 and a photo-setting compsn. for optical three- dimensional shaping contains the photo-setting liquid. In the formula I, X is a reside obtained by removing a hydroxyl group from tetravalent alcohol or (poly)ether tetraol, R<1> is a 2-6C alkylene group and A is an org. group represented by either one of formulae II, III (wherein R<2> is a 2-6C alkylene group).
