摘要:
Hollow resin particles, a production process for producing the same and application thereof. The hollow resin particles include a thermoplastic resin shell and a hollow part surrounded by the shell. The thermoplastic resin is a polymer produced from a polymerizable component containing 0.6 to 3.0 wt % of a crosslinkable monomer having at least two polymerizable carbon-carbon double bonds per molecule and 97 to 99.4 wt % of an uncrosslinkable monomer having one polymerizable carbon-carbon double bond per molecule. A blowing agent is encapsulated in the hollow resin particles. The blowing agent contains 50 to 100 wt % of an organic compound having a vapor pressure higher than 100 kPa at 25° C. Further, the encapsulation ratio of the blowing agent ranges from 3 to 13 wt % of the hollow resin particles.
