    摘要: A liquid photocurable resin composition contains a (meth)acrylate oligomer component, an alkyl (meth)acrylate monomer component, and a photopolymerization initiator component. The (meth)acrylate oligomer component contains at least one oligomer selected from the group consisting of a polyurethane (meth)acrylate oligomer, a polyisoprene (meth)acrylate oligomer, a polybutadiene (meth)acrylate oligomer, and a polyether (meth)acrylate oligomer that have a weight average molecular weight of 1,000 to 200,000. The photopolymerization initiator contains a molecule cleavage-type photoradical polymerization initiator and a hydrogen-abstracting photoradical polymerization initiator at a ratio by mass of 10:1 to 10:35. The cured resin that is obtained by photoradical polymerization of the photocurable resin composition has a glass transition temperature of −40 to 20° C. when the composition is cured at a curing ratio of the outermost surface of more than 90%.

    摘要: The present invention provides a photosensitive resin composition and a photosensitive dry film resist produced therefrom, and further provides a photosensitive dry film resist having excellent flame-retardant properties. More specifically, the present invention provides a photosensitive dry film resist and photosensitive coverlay film produced from a photosensitive resin composition consisting mainly of soluble polyimide, a compound having a carbon-carbon double bond, and a photoreactive initiator and/or sensitizer that have excellent workability, can be developed in an alkaline solution, and meet the standard for tests for flammability of plastic materials known as UL94V-0. The photosensitive coverlay film of the present invention can be attached without any adhesives and has an excellent heat resistance, so that it is suitably used for a printed wiring board to be used in the electronic material field, for hard disc suspension, and for a hard disc head for a personal computer.
