Abstract
The present invention relates to a high-refractive and high-adhesion epoxy resin composition and an encapsulation material including the same, and to a high-refractive and high-adhesion epoxy resin composition, which can be applied to various methods of spraying a low-viscosity liquid and filling and curing a gap, such as an inkjet, dispense coating method, or the like, has excellent light extraction efficiency, high adhesion, and low outgassing properties during curing, and can bond and mold glass components of organic or inorganic light-emitting display screen, and an encapsulation material including the same.
Claims8
A high-refractive and high-adhesion epoxy resin composition comprising:
- (a) a high refractive index epoxy resin represented by the following Chemical Formula 1;
- (b) a high-reliability diluted epoxy resin including a substituted or unsubstituted cycloaliphatic group having 10 to 100 carbon atoms;
- and
- (c) a non-yellowish adhesive epoxy resin represented by the following Chemical Formula 2,
- in Chemical Formula 1, the ring indicated by the dotted line is a group fused to an adjacent 6-membered ring structure and is one of a substituted or unsubstituted C6 to C60 monocyclic aryl, a substituted or unsubstituted C6 to C60 condensed ring aryl, a substituted or unsubstituted C6 to C60 aryloxy group, a substituted or unsubstituted C6 to C60 monocyclic heteroaryl group, and a substituted or unsubstituted C6 to C60 condensed ring heteroaryl group, and m and n are, each independently, integers from 0 to 4, but both are not 0, and
- in Chemical Formula 2, G is an organic group-containing a glycidyl group, X1 and X2 are, each independently, hydrogen or a methyl group, p is an integer of 1 to 10, and R is a substituted or unsubstituted C10 to C100 alkylene group or alkenylene group.
