Abstract
The aqueous emulsion paints according to the invention contain urea-formaldehyde white pigments having very characteristic physical properties. Compared with aqueous emulsion paints according to the prior art, which in addition to TiO.sub.2 can contain only a maximum of 20% by weight of UF white pigments based on the entire content of white pigments, according to the invention TiO.sub.2 may be substituted up to 100% by the UF white pigment. The resultant finishes are fast to light, weather and abrasion.
