1. A surface sealing agent for an organic EL element, comprising:
an epoxy resin (A) having two or more epoxy groups in a molecule; and a curing accelerator (B) comprising at least one compound selected from the group consisting of a salt (B1) of a quaternary ammonium ion represented by the following general formula (1):[Formula 1](wherein R1, R2, and R3 each independently represent a C1-10 alkyl group which may have a substituent, a C6-10 aryl group which may have a substituent, or a C7-20 aralkyl group which may have a substituent, and Ar represents a C6-10 aryl group which may have a substituent) and a salt (B2) of a quaternary ammonium ion represented by the following general formula (2):[Formula 2](wherein R4, R5, and R6 each independently represent a C1-10 alkyl group which may have a substituent, a C6-10 aryl group which may have a substituent, or a C7-20 aralkyl group which may have a substituent, and Ra, Rb, and Rc each independently represent a hydrogen group, a C1-10 alkyl group, a C1-10 alkoxy group, F, Cl, Br, I, NO2, CN, or a group represented by the following general formula (3):[Formula 3](wherein R7, R8, and R9 each independently represent a hydrogen group or a C1-10 hydrocarbon group), wherein
0.1 to 10 parts by weight of the curing accelerator (B) is contained based on 100 parts by weight of the surface sealing agent. |
