Problems solved by technology

[0004] However, such an organic EL display element has a problem that if the organic light-emitting material layer and electrodes are exposed to outdoor air, the light-emitting characteristics will deteriorate rapidly and the life will be shortened.
However, there is a problem that when a photocurable adhesive is used in this way, degassing occurs when light is irradiated and the inside of the device is filled, which accelerates the deterioration of the device.

Embodiment 2～6、 comparative example 1～3

[0086] According to the compounding ratio of Table 1, each material described in Table 1 was stirred and mixed similarly to Example 1, and the photopost-curable resin composition was produced.

[0087]

[0088] The following evaluations were performed about each photopost-curable resin composition obtained in the Example and the comparative example. The results are shown in Table 1.

[0089] (1) Viscosity

[0090] About each photopost-curable resin composition obtained by the Example and the comparative example, the viscosity in 25 degreeC and conditions of 100 rpm was measured using the E-type viscometer (made by Toki Sangyo Co., Ltd., "VISCOMETER TV-22").

Abstract

The purpose of the present invention is to provide a photo-post-curing resin composition that makes it possible to suppress the generation of outgas and has exceptional transparency and reliability. The present invention is a photo-post-curing resin composition containing a cationically curable resin, a photo-cationic polymerization initiator, and a compound having amino groups and cationically polymerizable functional groups.

Description

technical field [0001] The present invention relates to a photopost-curable resin composition capable of suppressing the occurrence of outgassing and excellent in transparency and reliability. Background technique [0002] In recent years, research on organic light-emitting devices using organic thin-film elements such as organic electroluminescence (organic EL) display elements and organic thin-film solar cell elements is ongoing. An organic thin film element can be easily produced by vacuum deposition, solution coating, etc., and thus is also excellent in productivity. [0003] An organic EL display element has a thin-film structure in which an organic light-emitting material layer is sandwiched between a pair of electrodes facing each other. In this organic light-emitting material layer, electrons are injected from one electrode and holes are injected from the other electrode, whereby electrons and holes are combined in the organic light-emitting material layer to perfor...
