The invention provides a process for the preparation of water-reducible carboxylated amide binders comprising the consecutive steps: A. reacting: 1. a substantially epoxy-free compound of general formula wherein A is the organic residue of a ring opening reaction of a vicinal epoxy group of a polyepoxide with ammonia or an amine having at least two amino hdyrogens, R , R and R each is hydrogen or a C1-6 alkyl group, with the proviso that at least one of R , R and R is hydrogen, R is a C2-12 alkylene group, x is 0 or 1 and y is a number from 0 to 4, with 2. a carboxyl group-containing mono- or polyester compound derived from a di- or polycarboxylic acid and a polyhydric alcohol having at least one glycol group per molecule, with the proviso that only one carboxyl group per molecule of di- or polycarboxylic acid has been esterified and the or each ester group is a beta -hydroxyester group, at a temperature in the range of from 80 to 160 DEG C, and B. neutralizing the carboxylic groups or the residual amine groups in the product of step A. ,
