Problems solved by technology

However, the resistance of organic EL elements to moisture is very weak, and there are problems in that the light-emitting material (light-emitting layer) is deteriorated due to moisture, and the luminance is reduced, or no light is emitted, or the interface between the electrode and the light-emitting layer is affected by moisture. peeling off occurs, or the metal oxidizes to become a high resistance

manufacture example 1

[0150] Varnishes having the compounding ratios shown in Table 1 below were prepared according to the following procedure. Using a three-roll mill, maleic anhydride-modified liquid polybutene (HV-300M, manufactured by Nippon Mitsubishi Corporation), polybutene (HV-1900, manufactured by Nippon Mitsubishi Corporation) and semi-calcined hydrotalcite (hygroscopic filler ; DHT-4C, manufactured by Kyowa Chemical Co., Ltd.) was dispersed in a product obtained by dissolving a saturated hydrocarbon resin (tackifier; ARKON P125) containing a cyclohexane ring in SWASOL so that the solid content became 60%, and a mixture was obtained. . In the obtained mixture, a glycidyl methacrylate modified polypropylene-polybutene copolymer (T-YP341 (manufactured by Starlight PMC Co., Ltd.), SWASOL solution, solid content 20%), an anionic polymerization type curing agent (TAP, Kayaku Akzo Co., Ltd.) and toluene, and the resulting mixture was uniformly dispersed with a high-speed rotary mixer to obtain...

[0154] Varnishes having the compounding ratios shown in Table 1 below were prepared according to the following procedure. Using a three-roller mill, maleic anhydride-modified liquid polybutene (HV-300M, manufactured by Starlight PMC Company), polybutene (HV-1900, manufactured by Starlight PMC Company) and plate glass filler (FTD010-F01, Japan Panglass Co., Ltd.) was dispersed in a product obtained by dissolving a cyclohexane ring-containing saturated hydrocarbon resin (tackifier; ARKONP125) in SWASOL so that the solid content became 60%, to obtain a mixture. In the obtained mixture, a glycidyl methacrylate modified polypropylene-polybutene copolymer (T-YP341 (manufactured by Starlight PMC Co., Ltd.), SWASOL solution, solid content 20%), an anionic polymerization type curing agent (TAP, Kayaku Akzo Co., Ltd.) and toluene, and the obtained mixture was uniformly dispersed with a high-speed rotary mixer to obtain a varnish of a low moisture permeability resin composition.

Abstract

The purpose of the present invention is to provide a resin sheet with a sealing support, which suppresses damage to and deterioration of an organic EL device in a sealing process, and with which an organic EL device exhibiting higher moisture blocking properties and having high reliability can be obtained. This resin sheet with a support is provided with a support and a resin sheet on the support, wherein: the resin sheet has at least one hygroscopic layer which is formed of a hygroscopic resin composition, and at least one low moisture permeable layer which is formed of a low moisture permeable resin composition; the at least one low moisture permeable layer is provided on a side opposite to the support with respect to the hygroscopic layer; the hygroscopic resin composition includes a hygroscopic filler; and the low moisture permeable resin composition includes a plate-shaped filler.

Description

technical field [0001] The present invention relates to a resin sheet with a support, and relates to a resin sheet with a support suitable for sealing electronic components, especially light-emitting elements such as organic EL (Electroluminescence) elements, optical semiconductors, and light-receiving elements such as solar cells. material. Background technique [0002] An organic EL element is a light-emitting element using an organic substance as a light-emitting material, and has attracted attention in recent years because it can obtain high-intensity light emission at a low voltage. However, the resistance of organic EL elements to moisture is very weak, and there are problems in that the light-emitting material (light-emitting layer) is deteriorated by water, and the brightness is reduced, or light is not emitted, or the interface between the electrode and the light-emitting layer is affected by water. Then, peeling occurs, or the metal oxidizes, resulting in high res...
