    摘要: Disclosed is a resin particle having excellent low-temperature fusibility, having a sufficiently narrow size distribution, and that is obtained using a liquid or supercritical fluid. In the resin particle (C), which comprises a microparticle (A) containing a resin (a) being coated to or adhered to the surface of a resin particle (B) that contains another resin (b), the degree of swelling of the microparticle (A) resulting from liquid or supercritical carbon dioxide (X) at a temperature less than the glass transition temperature or the melting point of the microparticle (A) is no greater than 16%, and with the resin (a) as a constituent unit, the resin particle (C) contains 0.1-50 wt% of a non-crystalline non-halogen vinyl monomer (m1) of which the solubility parameter (SP value: (cal/cm 3 ) 1/2 ) is 7-9.

    摘要: Provided is a contact lens material having a smooth surface with good water wettability and durability. In the method of manufacturing a contact lens material comprising a contact lens base material and a coating formed on at least a portion of a surface of the above base material, the contact lens base material is processed by plasma polymerization in a mixed gas atmosphere of methane and moist air, and then treated with plasma in a nonpolymerizable gas atmosphere to form the above coating. Further provided is a method of manufacturing a soft contact lens wherein water is introduced into the contact lens material manufactured by the above method to obtain a soft contact lens.
