Abstract
A clear polymeric matte coating including from 10% to 65% by weight, based on the weight of the coating, of a first polymer having a calculated Tg of from −60° C. to 100° C.; from 10% to 80% by weight, based on the weight of the coating, of a second particulate polymer having an average particle diameter of from 0.5 microns to 30 microns; and from 0.1% to 15% by weight, based on the weight of the coating, of an aminosilane is provided. Also provided is an aqueous polymeric coating composition form which the clear matte coating may be formed and a method for improving the matting efficiency of an emulsion polymer having a calculated Tg of from −60° C. to 150° C. and an average particle diameter of from 0.5 microns to 30 microns in a coating.
