Patent ID: 7868069

Claim:
A process for producing particles comprising a resin component (A), the process comprising: kneading the resin component (A) comprising a thermoplastic resin with an auxiliary component (B) comprising at least an oligosaccharide (B 1 ) and a water-soluble plasticizing component (B 2 ) for plasticizing the oligosaccharide (B 1 ) wherein the water-soluble plasticizing component (B 2 ) is at least one member selected from the group consisting of a monosaccharide, a disaccharide and a sugar alcohol, to provide a dispersed composition, wherein the dispersed composition comprises a continuous phase comprising the auxiliary component (B) and a dispersed phase as the particles comprising the resin component (A), and the dispersed composition has an islands-in-the-sea structure, and eluting an auxiliary component (B) from the dispersed composition, wherein the average particle size of the particles is 0.1 to 100 μm, and the coefficient of variation of the particle size is not greater than 60.
