The present invention relates to an energy ray-curable resin composition for organic EL element sealing materials, which contains two or more compounds (A), for example, compounds represented by formula (1), said compounds (A) having two or more oxetane rings in each molecule. This resin composition has small curing shrinkage and provides a cured product that has excellent visible light transmittance, excellent light resistance, high Tg and low water vapor transmission rate. Consequently, this resin composition is useful as a solid sealing material for solid sealing of organic EL elements. (In formula (1), each R 1 independently represents a direct bond or a linear or branched chain hydrocarbon group having 1-6 carbon atoms; R 2 represents a linear or branched chain hydrocarbon group having 1-15 carbon atoms or a hydrocarbon group containing an alicyclic ring, an aromatic ring, a heterocyclic ring or a fused ring; each R 3 independently represents a linear or branched chain hydrocarbon group having 1-6 carbon atoms; and n represents 0 (zero) or an integer having an average of 1-5.) |
