Title:
SEALANT FOR ELECTRONIC DEVICES, AND SEALANT FOR ORGANIC EL DISPLAY DEVICES
Document Type and Number:
WIPO Patent Application WO/2019/117299
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sealant for electronic devices that excels in terms of low out-gas properties and in wetting spreadability on a substrate or inorganic material film. The purpose of the present invention is also to provide a sealant for organic electroluminescence (EL) display elements, the sealant being formed using the sealant for electronic devices. The present invention is a sealant for electronic devices, the sealant containing a curable resin, and a polymerization initiator and/or a thermosetting agent, wherein the curable resin contains a silicone compound represented by formula (1) and a silicone compound represented by formula (3). In formula (1), R1 represents a C1-10 alkyl group, each instance of which may be the same or different. X1 and X2 each independently represent a C1-10 alkyl group or a group represented by formula (2-1), (2-2), (2-3), or (2-4). At least one of X1 and X2 represents a group represented by formula (2-1), (2-2), (2-3), or (2-4). In formulas (2-1) through (2-4), R2 represents a bond or a C1-6 alkylene group, R3 in formula (2-3) represents a hydrogen atom or a C1-6 alkyl group, R4 in formula (2-3) represents a bond or a methylene group, and R5 in formula (2-4) represents a hydrogen atom or a methyl group. In formula (3), R6 represents a C1-10 alkyl group, each instance of which may be the same or different. X3 and X4 each independently represent a C1-10 alkyl group or represent a group represented by formula (4-1), (4-2), (4-3), or (4-4), and X5 represents a group represented by formula (4-1), (4-2), (4-3), or (4-4). The letter m represents an integer of 0-1000 inclusive, and the letter n represents an integer of 1-100 inclusive. In formulas (4-1) through (4-4), R7 represents a bond or a C1-6 alkylene group, R8 in formula (4-3) represents a hydrogen atom or a C1-6 alkyl group, R9 in formula (4-3) represents a bond or a methylene group, and R10 in formula (4-4) represents a hydrogen atom or a methyl group.
