<p>A soil resistant aqueous coating composition in which the binder consists of a blend of a low Tg polymeric dispersion and a high Tg polymeric dispersion. The PVC of the composition is less than the critical PVC and the Tg of the low Tg polymer dispersion is less than 0 °C and the Tg of the high Tg polymer dispersion is at least 35 °C and the volume ratio of low Tg polymer dispersion to high Tg polymer dispersion is from 0.4:1 to 1.4:1.</p> |
