Title:
SEALANT FOR AN ELECTRONIC DEVICE AND SEALANT FOR AN ORGANIC EL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/117298
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sealant for an electronic device that is excellent in terms of low outgas characteristics, wet spreadability on a substrate or an inorganic material film, and transparency. The purpose of the present invention is also to provide a sealant for an organic EL display element using said sealant for an electronic device. The present invention is the sealant for an electronic device that contains a curable resin, and a polymerization initiator and/or a heat curing agent, wherein the curable resin contains a silicone compound expressed by formula (1), and the silicone compound expressed by formula (3), being the sealant for an electronic device for which the haze of the sealant for an electronic device overall is 10% or less. In formula (1), R1 represents a C1-10 alkyl group, and may be respectively the same or different. X1, X2 each independently represent a C1-10 alkyl group, or a group represented by formula (2-1), (2-2), (2-3), or (2-4). However, at least one of X1 and X2 represents the group represented by formula (2-1), (2-2), (2-3), or (2-4). In formulas (2-1) to (2-4), R2 represents a bond or a C1-6 alkylene group, in formula (2-3), R3 represents hydrogen or a C1-6 alkyl group, and R4 represents a bond or a methylene group, and in formula (2-4), R5 represents hydrogen or a methyl group. In formula (3), R6 represents a C1-10 alkyl group, and may be respectively the same or different. X3, X4 each independently represent a C1-10 alkyl group, or a group represented by formula (4-1), (4-2), (4-3), or (4-4). n is an integer of 1 to 1000. However, at least one of X3 and X4 represents a group represented by formula (4-1), (4-2), (4-3), or (4-4). In formula (4-1) to (4-4), R7 represents a bond or a C1-6 alkylene group, in formula (4-3), R8 represents hydrogen or a C1-6 alkyl group, R9 represents a bond or a methylene group, and in formula (4-4), R10 represents hydrogen or a methyl group.
