摘要： The invention provides a novel sulfonic acid or carboxylic acid containing a carbonyl group, or a salt thereof. The compound of the invention is represented by the following formula:
R 1 -C(=O)-(CR 2 2 ) n -(OR 3 ) p -(CR 4 2 ) q -L-A
wherein
R 1 is a linear or branched alkyl group containing one or more carbon atoms and optionally containing a substituent or a cyclic alkyl group containing three or more carbon atoms and optionally containing a substituent;
R 2 and R 4 are each individually H or a substituent;
R 3 is a C1-C10 alkylene group optionally containing a substituent;
n is an integer of 1 or greater;
p and q are each individually an integer of 0 or greater;
A is -SO 3 X or -COOX, wherein X is H, a metal atom, NR 5 4 , imidazolium optionally containing a substituent, pyridinium optionally containing a substituent, or phosphonium optionally containing a substituent, where R 5 s are each H or an organic group and are the same as or different from each other; and
L is a single bond, -CO 2 -B-*, -OCO-B-*, -CONR 6 -B-*,-NR 6 CO-B-*, or -CO- other than the carbonyl groups in -CO 2 -B-, -OCO-B-, -CONR 6 -B-, and -NR 6 CO-B-, where B is a single bond or a C1-C10 alkylene group optionally containing a substituent, R 6 is H or a C1-C4 alkyl group optionally containing a substituent, and * indicates the bond to A in the formula.-
