Abstract:
1. A thermally decomposing resin particle, which is a thermally decomposing hollow resin particle, and the hollow ratio at 23° C. is 5 to 95%, and which contains a polyoxyalkylene resin, and 10% by weight or more of the resin particle decomposes within an hour by heating at a prescribed temperature in a range from 100 to 300° C., and further contains a crosslinking component and has 10% compressive strength at 23° C. of 1 to 1000 MPa, and is obtained by using a monomer mixture containing a polyoxyalkylene macromonomer and an acrylic polyfunctional monomer, wherein an average particle diameter is 0.01 to 500 μm.
