Fine hollow particles comprising melamine-based resin

A method for producing a fine hollow particle composed of a resin film comprising a melamine-based resin, the method comprising:

• a first step:
• a step of preparing (a) an oil phase of an organic solvent;
• a second step:
• a step of preparing (b) a water phase containing a surfactant;
• a third step:
• a step of mixing and stirring the oil phase and the water phase to prepare an O/W emulsion in which the water phase forms a continuous phase and the oil phase forms a dispersed phase;
• a fourth step:
• a step of adding a melamine formaldehyde prepolymer compound as an additional phase to the O/W emulsion and promoting a condensation reaction of methylolated melamine, which is a melamine formaldehyde prepolymer compound, on an interface of the O/W emulsion to form a resin film, forming a fine particle encapsulating the oil phase, and obtaining a fine particle dispersion liquid in which the fine particle is dispersed;
• a fifth step:
• a step of separating the fine particle from the fine particle dispersion liquid;
• and
• a sixth step:
• a step of removing the oil phase from the inside of the fine particle to obtain the fine hollow particle, wherein a weight ratio of the (a) oil phase of the organic solvent to the (b) water phase containing the surfactant is 100 to 500 parts by mass of component (b), per 100 parts by mass of the component (a).
