This encapsulant for an organic electroluminescent element comprises a radically-polymerizable compound, a photopolymerization initiator, and a stable-radical-type compound having stable radicals. The radically-polymerizable compound contains an unsaturated alicyclic monomer having a radically-polymerizable group and an unsaturated aliphatic hydrocarbon ring. Cet agent d'encapsulation pour un élément électroluminescent organique comprend un composé polymérisable par voie radicalaire, un initiateur de photopolymérisation et un composé de type à radicaux stables ayant des radicaux stables. Le composé polymérisable par voie radicalaire contient un monomère alicyclique insaturé ayant un groupe polymérisable par voie radicalaire et un cycle hydrocarboné aliphatique insaturé. ラジカル重合性化合物と、光重合開始剤と、安定ラジカルを有する安定ラジカル型化合物と、を含有し、ラジカル重合性化合物が、ラジカル重合性基と不飽和脂肪族炭化水素環とを有する不飽和脂環式モノマーを含む、有機エレクトロルミネッセンス素子用封止剤。
