Abstract: A curable composite material composition comprising (A) a polymerizable unsaturated compound, (B) a fiber reinforcing material and/or fiber, and (C) a polymerization initiator comprising an organic boron compound represented by the general formula (1)  wherein R1, R2, R3 and R4 each independently represent an alkyl, aryl, allyl, aralkyl, alkenyl, alkynyl, silyl or heterocyclic group, a halogen atom, or a substituted alkyl, substituted aryl, substituted allyl, substituted aralkyl, substituted alkenyl, substituted alkynyl or substituted silyl group, and Z+ represents a cation, and an acidic compound, as well as a curing process for the curable composite material composition which includes irradiating and/or heating the curable composite material composition.

Abstract: A photocurable prepreg sheet for waterproofing includes (1) a fiber-reinforced resin layer which comprises a sheet-shaped inorganic or organic fibrous reinforcing material impregnated with a resin composition comprising: (A) an unsaturated polyester resin and/or vinyl ester resin: 100 parts by weight, and (B) at least two photopolymerization initiators having photosensitivity in different wavelength ranges from ultraviolet range to near infrared range: 0.01 to 10 parts by weight, and which is treated with light of a specific wavelength to thereby undergo prepolymerization which causes at least one of the polymerization initiators and radical-polymerizable unsaturated groups to remain partially intact; and (2) film which covers an upper surface and a back surface of the fiber-reinforced resin layer.

Abstract: A photocurable prepreg composition which is characterized by easy control of a B stage state of a thermosetting resin such as an unsaturated polyester resin or an epoxy acrylate resin, excellent storage stability, and remarkable curability after being shaped; as well as a production method therefor. A photocurable prepreg composition which contains an unsaturated polyester resin and/or an epoxy acrylate resin; at least two photopolymerization initiators with photosensitivity in different wavelength ranges; and an inorganic or an organic fiber-reinforcing material and/or filler, and which composition is treated with light of a specific wavelength such that at least one photopolymerization initiator and radical-polymerizable unsaturated groups remain partially in said resin; a production method therefor; and formed articles produced therefrom.

Abstract: A detergent for a contact lens comprising 40 to 80% by weight of fine particles of a water-soluble compound which has a salt value of at most 0.65 and a solubility in water of 3 to 30 at 30.degree. C. and at most 40 at 60.degree. C., with the product of the salt value and the solubility at 30.degree. C. being at most 10, and 100% of which passes a JIS standard sieve of a nominal size of 75 .mu.m, and 60 to 20% by weight of a pasting agent containing as a major component an aqueous dispersion of a gel composed of an acrylic acid compound having a recurring unit represented by the general formula (I): ##STR1## wherein R.sub.1 represents hydrogen atom and/or methyl group, R.sub.2 represents at least one member selected from hydrogen atom, sodium atom, potassium atom, lithium atom, NH.sub.
