Abstract
A matt paint which is mar-resistant is produced by the incorporation therein of polymer beads of two distinct size ranges, one range having diameters of from 2-10 micron and the other having diameters of from 10-40 micron, the total volume of beads comprising from 50-90% of the volume of the non-volatile content of the paint, and the beads of the larger size range comprising from 45-55% of the total bead volume. The reflectance of the paint is related to the size and the type of beads used.
