OPTICAL SHAPING INK SET, OPTICALLY SHAPED ARTICLE, AND METHOD FOR PRODUCING OPTICALLY SHAPED ARTICLE

摘要

The present invention relates to an optical shaping ink set in which a composition for model material comprises a monofunctional ethylenically unsaturated monomer (A) and a polyfunctional ethylenically unsaturated monomer (B), at least either of the monomer (A) or (B) has a hydroxyl group or an amino group, a total molar fraction of the hydroxyl group and the amino group is 5% to 30% with respect to a total amount of the monomer (A) and (B), or the composition for model material contains an ethylenically unsaturated monomer (C) of which a homopolymer has a Tg of 25° C. to 120° C., an ethylenically unsaturated monomer (D) of which a homopolymer has a Tg of −65° C. to 25° C., a bifunctional acrylate oligomer (E) having a Mw of 800 to 10,000, and an acylphosphine oxide compound, and a content of a bi- or higher functional acrylate compound is 15 to 100 parts by weight, and a composition for support material contains a water-soluble monofunctional ethylenically unsaturated monomer (a), a polyalkylene glycol (b) containing an oxyethylene group and/or an oxypropylene group, a water-soluble organic solvent (c), and a photopolymerization initiator (d).
