PHOTOCURABLE HYGROSCOPIC COMPOSITION AND ORGANIC EL DEVICE

摘要

A composition usable as a moisture absorbent for an organic electroluminescence device. A photocurable hygroscopic composition comprising (a) a moisture-reactive organic metal compound, (b) a (meth)acrylate, (c) a carboxyl group-containing polymerizable monomer, and (d) a photopolymerization initiator. The proportion of the moisture-reactive organic metal compound (a) is from 5 to 70 wt% based on the entire composition, and the proportion of the carboxyl group-containing polymerizable monomer (c) is from 0.1 to 50 mol% based on the moisture-reactive organic metal compound (a).
