<p>PROBLEM TO BE SOLVED: To provide a liquid resin composition for inkjet stereolithography, which can be colored in a full-color manner with a simple configuration of an apparatus and which gives a molded article excellent in hardness, strength, and storage property with light fastness.SOLUTION: The liquid resin composition for inkjet stereolithography essentially comprises the following components (A), (B), and (C): (A) an active ray-polymerizable organic compound; (B) a compound that generates an acid by irradiation with active rays; and (C) an acid-induced color developing dye precursor. For the active ray-polymerizable organic compound, a radical polymerizable organic compound and/or a cation polymerizable organic compound is used; for the compound that generates an acid by irradiation with active rays, a cationic photopolymerization initiator is used; and for the acid-color developing dye precursor, a color former is used. Visible rays are used as active rays. The liquid resin composition preferably further contains an ultraviolet ray absorbent.</p> |
