Abstract:
(EN) The present invention provides a composition for sealing an organic EL element, that can be stably applied using an inkjet printing method, and that can be quickly cured by irradiating light to form a cured object having excellent moisture resistance. The present invention is a composition for sealing an organic EL element, the composition being applied by inkjet printing, and containing a cationic polymerizable compound and a cationic polymerization initiator, wherein: the composition has a viscosity of 20 mPa∙s or less at 25°C; as a cationic polymerizable compound, the composition contains 50 wt% or more of an epoxy compound and/or a vinyl ether compound to the total amount of cationic polymerizable compound; the content of the cationic polymerizable compound having a viscosity of 100 mPa∙s or more at 25°C is 20 wt% or less of the total amount of the cationic polymerizable compound contained in the composition; and the content of the cationic polymerizable compound having a boiling point of 190°C or less at normal pressure is less than 20 wt% of the total amount of the cationic polymerizable compound contained in the composition.
(FR) La présente invention concerne une composition pour sceller un élément électroluminescent organique, qui peut être appliquée de façon stable à l'aide d'un procédé d'impression à jet d'encre, et qui peut être rapidement durcie par irradiation de lumière pour former un objet durci ayant une excellente résistance à l'humidité. La présente invention concerne une composition pour sceller un élément électroluminescent organique, la composition étant appliquée par impression à jet d'encre, et contenant un composé polymérisable cationique et un initiateur de polymérisation cationique : la composition ayant une viscosité de 20 mPa.s ou moins à 25 °C ; en tant que composé polymérisable cationique, la composition contenant 50 % en poids ou plus d'un composé époxy et/ou d'un composé d'éther vinylique de la quantité totale de composé polymérisable cationique ; la teneur du composé polymérisable cationique ayant une viscosité de 100 mPa.s ou plus à 25 °C étant de 20 % en poids ou moins de la quantité totale du composé polymérisable cationique contenu dans la composition ; et la teneur du composé polymérisable cationique ayant un point d'ébullition de 190 °C ou moins à une pression normale étant inférieure à 20 % en poids de la quantité totale du composé polymérisable cationique contenu dans la composition.
(JA) 本発明は、インクジェット印刷法により安定的に塗布することができ、光を照射することにより速やかに硬化して、防湿性に優れた硬化物を形成することができる有機EL素子封止用組成物を提供する。本発明のインクジェット印刷法により塗布するための有機EL素子封止用組成物は、カチオン重合性化合物とカチオン重合開始剤とを含有する組成物であって、25℃における粘度が20mPa・s以下であり、前記カチオン重合性化合物として、エポキシ化合物及び/又はビニルエーテル化合物を、カチオン重合性化合物全量の50重量%以上含有し、25℃における粘度が100mPa・s以上であるカチオン重合性化合物の含有量が組成物に含まれるカチオン重合性化合物全量の20重量%以下、常圧下における沸点が190℃以下であるカチオン重合性化合物の含有量が組成物に含まれるカチオン重合性化合物全量の20重量%未満である。
