Water-dilutable resins, process for preparing them, and their use

Resins AB which are dilutable in water following neutralization and have an acid number of from 25 to 160 mg/g, obtainable by reacting 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 polymer select...

Zusammenfassung:	Resins AB which are dilutable in water following neutralization and have an acid number of from 25 to 160 mg/g, obtainable by reacting 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 polymer selected from polyesters, dimerized and oligomerized unsaturated aliphatic carboxylic acids and polymers of olefinically unsaturated monomers, each having an acid number of from 30 to 240 mg/g, and B from 10 to 70% of at least one water-insoluble aldehyde resin or ketone resin obtainable by condensing ketones, ketones together with aldehydes, ketones with urea or aldehydes with urea, having a hydroxyl number from 20 to 300 mg/g, a softening point of from 60 to 140 DEG C. and a number-average molar mass of from 500 to 3000 g/mol.
