OPTICAL STEREOLITHOGRAPHIC-SHAPING PHOTOCURABLE RESIN COMPOSITION AND THREE-DIMENSIONAL SHAPED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a photocurable resin composition imparting a three-dimensional shaped article having high rigidity (a Young's modulus, a flexural elastic modulus) and high toughness (bending resistance, impact resistance).;SOLUTION: This photocurable resin composition 1 is a multilayer-structure polymer particle comprising: (A) a cationically polymerizable compound having two or more bisphenol structures and one or more hydroxy groups; (B) a cationically polymerizable compound except the (A) component; (C) a cationic photo polymerization initiator; (D) a radically polymerizable compound; (E) a radical photo polymerization initiator; and (F) a core and a shell layer. The shell layer contains a functional group-modified rubber-like polymerizable particle having at least one kind of a reactive functional group selected from a group comprising an epoxy group, a hydroxy group, a (meth)acryloyl group, and an oxetanyl group. The composition 1 is used as a material of cured layers 6, 7 in an optical shaping method, and forms a three-dimensional shaped article.;COPYRIGHT: (C)2009,JPO&INPIT
