Abstract:
A resin AB which is dilutable in water following neutralization and has an acid number of from 25 to 160 mg/g, obtained by reacting in a reaction mixture mass fractions, based in each case on the sum of the masses of the solids in the reaction mixture, of:A from 30 to 90% of at least one acid-functional component selected from one or more of polyesters, one or more of dimerized and oligomerized unsaturated aliphatic carboxylic acids, and one or more polymers of olefinically unsaturated monomers, each having an acid number of from 30 to 240 mg/g, andB from 70 to 10% of at least one water-insoluble aldehyde resin or ketone resin obtained by condensing one or more ketones, one or more ketones together with one or more aldehydes, one or more ketones with a urea, or one or more aldehydes with a urea; each resin having a hydroxyl number from 20 to 300 mg/g, a softening point of from 60 to 140.degree. C., and a number-average molar mass of from 500 to 3,000 g/mol,the sum of the mass fractions of A and B in the reaction mixture being 100%.
