Abstract
A curable composition comprising (A) a monomer mixture containing as an essential component thereof a mixture of 20 to 80% by weight of an aliphatic polyfunctional (meth)acrylate and 80 to 20% by weight of an aromatic vinyl compound, (B) an inorganic filler having an average particle diameter of not more than 5 microns, and (C) a catalytic amount of a polymerization initiator, and having said inorganic filler (B) dispersed in an amount of 250 to 800 parts by weight per 100 parts by weight of said monomer mixture (A).

A curable composition comprising (A) a monomer mixture containing as an essential component thereof a mixture of 20 to 80% by weight of an aliphatic polyfunctional (meth)acrylate and 80 to 20% by weight of an aromatic vinyl compound, (B) an inorganic filler having an average particle diameter of not more than 5 microns, and (C) a catalytic amount of a polymerization initiator, and having said inorganic filler (B) dispersed in an amount of 250 to 800 parts by weight per 100 parts by weight of said monomer mixture (A).
A method for the production of a curable composition, which comprises mixing (A) a monomer mixture containing as an essential component thereof a mixture of 20 to 80% by weight of an aliphatic polyfunctional (meth)acrylate and 80 to 20% by weight of an aromatic vinyl compound, (B) an inorganic filler having an average particle diameter of not more than 5 microns, and (C) a catalytic amount of a polymerization initiator, with a high-speed stirrer, with the total of said inorganic filler (B) falling in the range of 250 to 500 parts by weight based on 100 parts by weight of said monomer mixture (A), until the resulting blend forms a liquid possessing viscosity in the range of 2 to 100 poises.
