    摘要： The present invention provides a radically polymerizable curable resin obtained by modifying an epoxy resin by reacting a phenol compound having an alcoholic hydroxyl group; and an unsaturated monobasic acid, to the epoxy resin having two or more epoxy groups in a molecule. The epoxy resin is reacted with the phenol compound and the unsaturated monobasic acid. The curable resin is subjected to polymerization curing with heat or light to form a cured product having excellent heat resistance, moisture resistance, and adhesion to substrates. The present invention also provides a curable resin composition containing the curable resin, as well as an alkaline-developable curable resin capable of forming a coating layer having excellent tack-free property, quick developability and excellent properties of cured layer.

    摘要： The invention provides a photocurable resin composition which inhibits the deactivation of a bisacylphosphine oxide-series photopolymerization initiator and is useful for coating optical fibers. The photocurable resin composition comprises (A) a polyurethane (meth)acrylate oligomer, (B) an ethylenically unsaturated compound, (C) a bisacylphosphine oxide-series photopolymerization initiator, and (D) a tertiary amine and no tin component. Incorporation of the component (D) inhibits the decomposition and deactivation of the component (C). The component (A) may contain an aliphatic C.sub.14-40 polyol (hydrogenated dimerdiol, 12-hydroxystearyl alcohol) as a polyol component. This resin composition is used for a primary coating of a glass fiber or an indirect coating of an optical fiber through the primary layer, the coating layer being cured by light irradiation to provide an optical fiber coated with the resin composition.
