Abstract
A pigmented, aqueous coating composition comprising i) an aqueous dispersion of non-crosslinkable addition oligomer of weight average molecular weight of from 5000 to 15000 Daltons and calculated Fox Tg greater than 0° C. and less than 50° C. ii) an aqueous dispersion of addition polymer of weight average molecular weight greater than 53,000 Daltons, calculated Fox Tg greater than 10° C. and less than 40° C. and mean particle diameter of less than 150 nanometers, where the ratio of i):ii) is from 0.25:1 to 2.70:1, based on % weight dispersion solids.
