Patent attributes
Disclosed is a photocurable resin composition which is highly sensitive to ultraviolet light or visible light having a long wavelength, in particular a photocurable resin composition which is useful as a sealing agent. Specifically disclosed is a photocurable resin composition containing a component (a) which is composed of an anthraquinone derivative represented by the formula (I) below, and a component (b) which is composed of a compound having a (meth)acryloyl group in the molecule. The photocurable resin composition is characterized in that a part or the entire of the component (b) further contains an oxiranyl group in the molecule, and the component (a) content is 0.01-10% by mass relative to the component (b) content. [chemical formula 1] (I) (In the formula (I), X represents a phenyl group, an alkyl group having 1-8 carbon atoms, an alcoholic form of the phenyl group or the alkyl group, or a derivative of the alcoholic form.)
