## Abstract

A carboxylic acid or sulfonic acid salt containing a plurality of carbonyl groups, and a surfactant represented by the following formula: R1—C(═O)—R2—C(═O)—R3-A wherein R1, R2 and R3 are as defined herein, and A is —COOX or —SO3X, wherein X is H, a metal atom, NR44, imidazolium optionally containing a substituent, pyridinium optionally containing a substituent, or phosphonium optionally containing a substituent, where R4s are each H or an organic group and are the same as or different from each other; and any two of R1, R2, and R3 optionally bind to each other to form a ring.

## Claims

### Claim 1

A compound represented by the following formula:
wherein
R1 is a group represented by the following formula:
wherein n11 is an integer of 0 to 10; R11 is a methyl group; and R12 is a C0-C3 alkylene group, and when n11 is an integer of 2 to 10, R12s are the same as or different from each other;
R2 is a single bond or a divalent linking group;
R3 is a C1-C3 linear or branched alkylene group containing no carbonyl group;
R1, R2, and R3 contain nine or more carbon atoms in total;
A is —COOX or —SO3X, wherein X is H, a metal atom, NR44, imidazolium optionally containing a substituent, pyridinium optionally containing a substituent, or phosphonium optionally containing a substituent, where R4s are each H or an organic group and are the same as or different from each other; and
any two of R1, R2, and R3 optionally bind to each other to form a ring.

### Claim 2 (depends on 1)

wherein in the formula, R2 is a single bond, a linear or branched alkylene group containing one or more carbon atoms, or a cyclic alkylene group containing three or more carbon atoms, with a hydrogen atom that binds to a carbon atom being optionally replaced by a hydroxy group or a monovalent organic group containing an ester bond.

### Claim 3 (depends on 1)

The compound according to claim 1,
wherein in the formula, R2 is a linear or branched alkylene group containing no carbonyl group and containing one or more carbon atoms.

### Claim 4 (depends on 1)

The compound according to claim 1,
wherein in the formula, R2 is a C1-C3 linear or branched alkylene group containing no carbonyl group.

### Claim 5 (depends on 1)
