Claim 0:
1. Thermosensitive fine particles comprising:
a side chain crystal polymer which is crystallized at a temperature lower than a melting point of the side chain crystal polymer and which exhibits fluidity at a temperature equal to or more than the melting point of the side chain crystal polymer, wherein the side chain crystal polymer includes 20 to 100 parts by weight of a (meth)acrylate having a straight-chain alkyl group having 14 or more carbon atoms, 0 to 40 parts by weight of monofunctional monomer, and 0 to 10 parts by weight of multifunctional monomer,
wherein a difference between a refractive index of the thermosensitive fine particles at a temperature lower than the melting point of the side chain crystal polymer and a refractive index at a temperature equal to or more than the melting point of the side chain crystal polymer is 0.010 or more, and the thermosensitive fine particles have a mean particle diameter of 0.1 to 50 μm.
