Abstract

A resin including (i) a main chain portion containing a nitrogen atom, (ii) a group X that has a functional group having a pKa of 14 or less and is bonded to a nitrogen atom present in the main chain portion, and (iii) an oligomer chain or polymer chain Y having a number average molecular weight of from 500 to 1,000,000 in a side chain.

Claims

1. A resin comprising (i) a main chain portion containing a nitrogen atom, (ii) a group X that has a functional group having a pKa of 14 or less and is bonded to a nitrogen atom present in the main chain portion, and (iii) an oligomer chain or polymer chain Y having a number average molecular weight of from 500 to 1,000,000 in a side chain.

2. The resin of claim 1, wherein the (i) main chain portion containing a nitrogen atom of the resin includes an oligomer or polymer having an amino group.

3. The resin of claim 1, wherein the (i) main chain portion containing a nitrogen atom of the resin includes one or more selected from a poly(lower alkylene imine), a polyallylamine, a polydiallylamine, a metaxylenediamine-epichlorohydrin polycondensate, a polyvinylamine, a 3-dialkylaminopropyl (meth)acrylic acid amide copolymer, or a 2-dialkylaminoethyl (meth)acrylate copolymer.

4. The resin of claim 1, wherein the functional group having a pKa of 14 or less of the resin is a functional group selected from a carboxylic acid, a sulfonic acid, or —

COCH₂CO—

.

5. The resin of claim 1, wherein the resin includes a repeating unit represented by general formula (I-1) and a repeating unit represented by general formula (I-2):

6. The resin of claim 1, wherein the resin includes a repeating unit represented by general formula (II-1) and a repeating unit represented by general formula (II-2):

7. The resin of claim 1, wherein the (iii) oligomer chain or polymer chain Y having a number average molecular weight of 500 to 1,000,000 of the resin is represented by the following general formula (III-1):

8. The resin of claim 1, wherein the resin is a resin formed by reacting a resin having a primary or secondary amino group in a main chain portion with a precursor x of the group X having a functional group having a pKa of 14 or less and a precursor y of the oligomer chain or polymer chain Y having a number average molecular weight of from 500 to 1,000,000.

9. A method for producing the resin of claim 1, comprising synthesizing a resin having a primary or secondary amino group in a main chain portion, and then reacting the resin with a precursor x of the group X having a functional group having a pKa of 14 or less and a precursor y of the oligomer chain or polymer chain Y having a number average molecular weight of 500 to 1,000,000.

10. A pigment dispersion comprising (A) the resin of claim 1, (B) a pigment, and (C) a solvent.

11. A colored curable composition comprising (A) the resin of claim 1, (B) a pigment, (C) a solvent, (D) a photopolymerization initiator, and (E) a compound containing an ethylenically unsaturated double bond.

12. The colored curable composition of claim 11, further comprising (F) an alkali-soluble resin.

13. A color filter having a colored pattern formed by the colored curable composition of claim 11 on a support.

14. A method for producing a color filter, comprising applying the colored curable composition of claim 11 on a support to form a colored layer made of the curable composition, pattern-exposing the colored layer via a mask, and developing the colored layer after the exposure to form a colored pattern.
