Abstract
The present invention provides resin particles including polymer obtained of a monomer mixture containing a monofunctional (meth)acrylic ester monomer, a monomer represented by a general formula (I);
- where R1 is a hydrogen or a methyl group and n is an integer from 1 to 4, and a monomer represented by a general formula (II);CH2═C(R2)—COO—(CH2CH2O)m—CO—C(R2)═CH2 (II)where R2 is a hydrogen or a methyl group and m is an integer from 5 to 15. The resin particles have a volume average particle diameter of 5 to 50 μm, a recovery rate of 15% or more to less than 30%, and a compression strength (MPa) that provides a multiplication product in the range of 24.5 to 60.0 obtained by multiplying the compression strength and the volume average particle diameter (μm).
