<P>PROBLEM TO BE SOLVED: To provide a photocurable resin composition being superior in coatability and having a high moisture resistance when it is cured and further provide a sealing agent for an organic EL element composed of the photocurable resin composition and an organic EL element produced by using the photocurable resin composition and/or the sealing agent for an organic EL element. <P>SOLUTION: The photocurable resin composition contains a cationically polymerizable compound and a cationic photopolymerization initiator. The cationically polymerizable compound contains at least one type of epoxy resin selected from the group consisting of an epoxy resin having a biphenyl skeleton, an epoxy resin having a naphthalene skeleton, and an epoxy resin having an anthracene skeleton and contains an epoxy resin having a liquid aromatic cyclic skeleton at 25°C. In the cationically polymerizable compound, the content of a total of the epoxy resin having a biphenyl skeleton, the epoxy resin having a naphthalene skeleton, and the epoxy resin having an anthracene skeleton is 20% to 50% by weight, and the content of the epoxy resin having the liquid aromatic cyclic skeleton at 25°C is 50% to 80% by weight. <P>COPYRIGHT: (C)2012,JPO&INPIT |
