Abstract: PROBLEM TO BE SOLVED: To provide a photocurable resin composition capable of yielding a three-dimensional article having a high rigidity (Young's modulus, flexural modulus) and a high toughness (bending resistance, impact resistance). SOLUTION: The photocurable resin composition comprises (A) a cationically polymerizable compound having two or more bisphenol structures and one or more hydroxyl groups, (B) a cationically polymerizable compound other than the component (A), (C) a cationic photoinitiator, (D) a radically polymerizable compound, (E) a radical photoinitiator, and (F) multilayer polymer particles having a core and a shell layer, provided that the shell layer contains functional group-modified rubber polymer particles having at least one reactive functional group chosen from the group consisting of an epoxy group, a hydroxyl group, a (meth)acryloyl group and an oxetanyl group. The composition 1 is used as a material for preparing cured layers 6 and 7 in a photofabrication method to yield the three-dimensional article. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: 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

Abstract: PROBLEM TO BE SOLVED: To provide a photocurable composition for manufacturing a metal shaped article by using photo-shaping, from which the shaped article having excellent conductivity and a highly precise three-dimensional shape is easily manufactured. SOLUTION: The photocurable composition includes: a monomer having three or more ethylenically unsaturated groups (A); a photopolymerization initiator (B); and metal fine particles having a number-average particle diameter of 0.5-3 μm by a dynamic light scattering method (C). A mixing rate of the component (C) is 60-95 mass% when the whole quantity of the photocurable composition is set to be 100 mass%. Respective mixing rates of the component (A) and the component (B) are 70-95 mass% and 0.01-10 mass% when the whole quantity of the photocurable composition except for the component (C) is set to be 100 mass%. The composition 1 is utilized as a material for cured article layers 6, 7 in the photo-shaping and forms a three-dimensional shaped article. The metal shaped article is obtained by baking the three-dimensional shaped article. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a photocurable composition capable of highly precisely and easily producing a carbonized shaped article giving a high carbonization yield and having a fine three-dimensional shape. SOLUTION: The photocurable composition includes (A) a polyfunctional epoxy compound having an aromatic ring structure in the main chain and (B) a cationic photoinitiator. The component (A) is exemplified by a naphthalene skeleton type epoxy resin, biphenyl skeleton type epoxy resin, anthraquinone skeleton type epoxy resin, phenol novolac skeleton type epoxy resin and cresol novolac skeleton type epoxy resin. The photocurable composition can include (C) a monomer having two or more ethylenic unsaturated groups and (D) a polyfunctional phosphate compound and the like. The composition 20 is used as a material of curing layers 19 in a micro stereolithography and becomes a three-dimensional shaped article. When the three-dimensional shaped article is baked, the carbonized shaped article is prepared. COPYRIGHT: (C)2009,JPO&INPIT
