<p>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);
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCH 2 =C(R 1 )-COO-(CH 2 CH 2 O) n -CO-C(R 1 )-CH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(I)
where R 1 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);
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCH 2 -C(R 2 )-COO-(CH 2 CH 2 O) m -CO-C(R 2 )=CH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(II)
where R 2 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).</p> |
