PROBLEM TO BE SOLVED: To provide styrene-acrylic resin particles for shrink inhibitors which reduce VOC, and can give desired shrink inhibition function to a molded product. SOLUTION: The styrene-acrylic resin particles for shrink inhibitors in curing a molding material which are derived from a monomer mixture comprising 50-80 wt.% of a monofunctional styrene monomer and 50-20 wt.% of an acrylic acid monomer, has a weight-average molecular weight of 50,000-500,000, and contains diallyl phthalate and an unsaturated polyester resin.
