Abstract: Urea-aldehyde condensates (I) are claimed, as obtd. by reaction of (a) 1 mol. urea of formula (II) with 1.9 (n + 1)-2.2 (n +1) mol. aldehyde of formula (III) at 60-120 deg. C in the presence of acid, (b) reaction of the precondensate obtd. with a mixt. of 2.8-3.2 mol. formaldehyde and 2.8-3.2 mol. (III) at 60-120 deg. C, (c) removal of water and (d) further reaction of the resin with alkali metal alcoholate at 80-100 deg. C. X = O or S; A = 1-6C alkylene; n = 0-3; R1, R2 = up to 20C hydrocarbyl. The process itself is also claimed. Pref. (II) is urea, thiourea, methylenediurea or hexamethylenediurea; (III) is isobutyraldehyde (IV), 2-methylpentanal, 2-ethylhexanal or 2-phenylpropanal.

Abstract: A process for the preparation of stable aqueous aldehyde resin dispersions and for the production of surface coating binders. For this purpose, a melt or highly concentrated solution of a polycondensate of urea and a CH-acidic aldehyde, with or without formaldehyde, is dispersed in water in the presence of an organic protective colloid and, if required, an emulsifier. These aqueous resin dispersions can be used, in combination with other film formers, as surface coating binders.
