(57) 【Abstract】 PROBLEM TO BE SOLVED: Various problems of a three-dimensional cured product after radical polymerization of a radical polymerizable resin by heat or light, that is, volume shrinkage, insufficient toughness, and low impact resistance. It is an object to improve defects such as heat resistance, dimensional defect, low heat resistance, and low water resistance by a simple method. A polymer fine particle-dispersed radically polymerizable resin composition of the present invention is a radical polymerization in which polymer fine particles (B) are dispersed in an insoluble state in a radically polymerizable resin (A) capable of having a high molecular weight by radical polymerization. Resin composition, wherein the composition is a radically polymerizable resin (A) Is obtained by adding the emulsion of the polymer fine particles (B) to the radically polymerizable resin (A) and / or its raw material at an arbitrary stage in the production process of, and then performing a dehydration process thereafter. |
