PROBLEM TO BE SOLVED: To provide resin particles which are obtained by using a resin having high dispersibility into a fluid in a liquid state or a supercritical state, and a fluid in a liquid state or a supercritical state, have a sufficiently narrow particle size distribution, and have excellent low-temperature meltability.SOLUTION: A resin (a) has a monomer (m1) as an essential constituent monomer, has a ratio of 0.1-35 wt.% of the monomer (m1) based on the weight of the resin (a), and satisfies the following conditions 1 and 2: [condition 1] the resin (a) has a glass transition temperature (TGa) and/or a melting point (TMa), at least one thereof is 30-150°C, and a weight average molecular weight of the resin (a) is 200,000 or less; and [condition 2] a number average molecular weight of the monomer (m1) is 100-30,000, and a solubility parameter (SP value) of the monomer (m1) is 7.0-9.5.SELECTED DRAWING: None |
