Abstract
Fine polymer particles are dispersed as primary particles in a vinyl monomer to provide a high quality composition in which the dispersed state and stability of the particles are regulated to a high degree and to provide a curable composition being excellent in handleability and using fine polymer particles as a toughness-imparting agent. For the above, the curable composition of the present invention comprises 100 parts by weight of a vinyl monomer (A) and 0.1 to 100 parts by weight of fine polymer particles (B) having a volume average particle size of 0.05 to 1 m, in which the fine polymer particles (B) are dispersed in the form of primary particles in the vinyl monomer (A).
