PROBLEM TO BE SOLVED: To provide a manufacturing method of a photosetting composition where photoset body is dissolved by a solvent.SOLUTION: A manufacturing method of a photosetting resin composition includes: a process 1 of selecting an oligomer compound A having a (meth)acrylate group, a specific radical polymerizable unsaturated bond-containing compound B, a photopolymerization initiator compound C and a reaction inhibitor compound D; a process 2 of preparing blended amount of the components A to D; a process 3 of obtaining a blended compound by blending the components A to D; a process 4 of irradiating ultraviolet ray to the blended compound to obtain a photoset body; and a process 5 of adding a specific amount of a solvent to a specific amount of the photoset body and standing them under specific environment for 24 hours, then conducting a solvent dissolving test for confirming presence or absence of residuals and determining presence level 1 or absence level 2. A blended composition at level 2 by repeating processes 1 to 5 is set as a photosetting resin composition. In the resulting composition, the component B is 1 to 1000 pts.mass based on 100 pts.mass of the component A, the component C is 0.1 to 100 pts.mass and the component D is 0 to 1000 pts.mass based on 100 pts.mass of total of the components A and B.SELECTED DRAWING: None
