Abstract

Aq. dispersions of etherated amino resins (I), contg. (A) 10-50% etherated or partly etherated amino resin, (B) 0-15% 1-10C linear or branched alkanol, (C) 89.9-32.5% water and (D) 0.1-5.5% anionic emulsifiers. Also claimed are: (i) a process for the prodn. of (I), by mixing (A) with (D) and combining the mixt. with water in a suitable mixer; (ii) one-component paints contg. dispersions (I) and aq. dispersions of OH gp.-contg. binders; (iii) two-component paints as in (i), pref. also contg. aq. isocyanate dispersions. Pref. resins (A) comprise reaction prods. of aliphatic aldehydes such as formaldehyde, glyoxal and/or furfural with amino resin- formers, pref. melamine, ammeline, ammelide, acetoguanamine, benzoguanamine, caproguanamine, urea, thiourea, ethylene-urea, propylene-urea and/or acetylene-urea. Resins (A) are partly or completely etherated with 1-10C linear or branched alkanols. Emulsifiers (D) have hydrophobic segment(s) and one hydrophilic segment, or at least two hydrophilic segments, of which at least one has non-ionic properties and at least one has anionic properties. A soln. of (A) in alkanol (B) is mixed with (D), and this phase is then mixed with water at 20-95 degrees C.
