Abstract

Official abstract text for this publication.

The present application relates to a compound of Formula 1, a binder resin, a negative-type photosensitive resin composition, and a display device comprising a black bank formed using same.

First claim

Opening claim text (preview).

The invention claimed is: 1. A compound represented by the following Formula 1: wherein, in the Formula 1, R1 and R2 are the same as or different from each other, and are each independently hydrogen; —CO-L-R; or —CONR′R″, L is a substituted or unsubstituted alkenylene group; a substituted or unsubstituted cycloalkenylene group; or a substituted or unsubstituted arylene group, R, R′, and R″ are the same as or different from each other, and are each independently hydrogen; —COOH; or a substituted or unsubstituted alkyl group, R3 and R4 are the same as or different from each other, and are each independently hydrogen; or a substituted or unsubstituted alkyl group, r3 and r4 are an integer from 0 to 4, and when r3 is 2 or higher, R3s are the same as or different from each other, and when r4 is 2 or higher, R4s are the same as or different from each other, L1 and L2 are the same as or different from each other, and are each independently a substituted or unsubstituted alkylene group, M1 and M2 are -M1′-M2′-M3′-, M1′, M2′ and M3′ are the same as or different from each other, and are each independently a direct bond; —SO 2 —; a substituted or unsubstituted alkylene group; or a substituted or unsubstituted arylene group, and n is an integer from 1 to 30. 2. The compound of claim 1 , wherein M1′ and M3′ are the same as or different from each other, and are each independently a direct bond; or a substituted or unsubstituted arylene group, and M2′ is a direct bond; —SO 2 —; or a substituted or unsubstituted arylene group. 3. The compound of claim 1 , wherein M1 and M2 are each represented by the following Formula 2: in the Formula 2, means a moiety linked to the Formula 1, M2′ is as defined in claim 1 , R13 and R14 are the same as or different from each other, and are each independently hydrogen; a hydroxyl group; or a substituted or unsubstituted alkyl group, and r13 and r14 are an integer from 1 to 4, and when r13 is 2 or higher, R13s are the same as or different from each other, and when r14 is 2 or higher, R14s are the same as or different from each other. 4. The compound of claim 1 , wherein R1 and R2 are hydrogen. 5. The compound of claim 1 , wherein R1 is —CO-L-R; or —CONR′R″, and L, R, R′, and R″ are as defined in claim 1 . 6. The compound of claim 1 , wherein the compound has a weight average molecular weight of 3,000 g/mol to 8,000 g/mol.
