Patent ID: 11713366

Abstract:
The present invention provides a resin composition for a model material, for obtaining an optically shaped article that has flexibility and does not crack even when it is bent, and a method for manufacturing optically shaped articles that are shaped using the resin composition for a model material. The present invention relates to a resin composition for a model material, comprising, based on 100 parts by weight of a whole resin composition, 20 to 90 parts by weight of a (meth)acrylate monomer represented by the following formula (1) and/or a (meth)acrylate monomer represented by the following formula (2) as a monofunctional monomer (A), and 5 parts by weight or more of a polyfunctional oligomer as an oligomer (B), and further comprises no or 15 parts by weight or less, based on 100 parts by weight of the whole resin composition, of polyfunctional monomer (C), wherein R1, R2 and R3 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 3 carbon atoms.
