Title:
CURABLE RESIN COMPOSITION AND SEALING AGENT FOR ORGANIC ELECTROLUMINESCENT DISPLAY ELEMENTS
Document Type and Number:
WIPO Patent Application WO/2018/030232
Kind Code:
A1
Abstract:
One purpose of the present invention is to provide a curable resin composition which is capable of suppressing the generation of an outgas, while having excellent coatability. Another purpose of the present invention is to provide a sealing agent for organic electroluminescent display elements, which is composed of this curable resin composition. The present invention is a curable resin composition which contains a cationically polymerizable compound and a cationic polymerization initiator, and wherein the cationically polymerizable compound contains at least one compound selected from the group consisting of compounds represented by formula (1-1), compounds represented by formula (1-2) and compounds represented by formula (1-3). In formula (1-1), R1 represents a bonding hand, a linear or branched alkylene group having 1-18 carbon atoms or a linear or branched alkenylene group having 2-18 carbon atoms; and each of R2 and R3 independently represents a hydrogen atom or a linear or branched alkyl group having 1-18 carbon atoms. In formula (1-2), R4 represents a linear or branched alkylene group having 3-18 carbon atoms or a linear or branched alkenylene group having 3-18 carbon atoms; and each of R5 and R6 independently represents a hydrogen atom or a linear or branched alkyl group having 1-18 carbon atoms. In formula (1-3), each of R7 and R8 independently represents a linear or branched alkylene group having 1-18 carbon atoms or a linear or branched alkenylene group having 2-18 carbon atoms; and each of R9-R12 independently represents a hydrogen atom or a linear or branched alkyl group having 1-18 carbon atoms.
