Abstract:
1. A curable composition comprising 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 μm, said fine polymer particles (B) being dispersed in the form of primary particles in said vinyl monomer (A), wherein said vinyl monomer (A) comprises at least one selected from the group consisting of a (meth)acrylate monomer synthesized from an alcohol having 3 or more carbon atoms and (meth)acrylic acid, a hydroxyethyl(meth)acrylate, an aromatic vinyl monomer and a vinyl ether monomer; the total amount of the (meth)acrylate monomer synthesized from an alcohol having 3 or more carbon atoms and (meth)acrylic acid and the hydroxyethyl(meth)acrylate in said vinyl monomer (A) is more than 50 wt % and not more than 100 wt %; said fine polymer particles (B) are particles of a core/shell graft copolymer; and said shell layer comprises a copolymer of 100 wt % in total of shell layer monomers comprising 2 to 90 wt % of at least one monomer (BS-1) selected from the group consisting of an alkoxyalkyl(meth)acrylate, hydroxyalkyl(meth)acrylate and glycidyl(meth)acrylate, 2 to 98 wt % of at least one monomer (BS-2) selected from the group consisting of an alkyl(meth)acrylate, styrene, α-methylstyrene and (meth)acrylonitrile, 0 to 10 wt % of a polyfunctional vinyl monomer (BS-3), and 0 to 10 wt % of other vinyl monomer (BS-4) being copolymerizable with those monomers.
