Abstract
A protective colloid-free plastics dispersion yielding after drying a polymer film which under the influence of moisture has no or little tendency to whitening contains polymer particles having a bimodal size distribution, that is, on the one hand relatively coarse particles and on the other hand relatively fine particles. The polymer component consists of at least 10 weight % of particles having an average diameter of less than 0.2 .mu.m and of 90 weight % at most of particles having an average diameter of more than 0.25 .mu.m, and the ratio of average grain size of coarse to fine polymer is at least 2:1. The plastics dispersion is suitable especially as binder dispersion in plasters and gloss paints.
