Abstract
A coating composition having increased block resistance comprising a polymer prepared by emulsion polymerizing at least one ethylenically unsaturated non-carboxy functional monomer, from 0.01 to 2 pphm of a sterically hindered alkoxylated silane monomer, and at least one anionic surfactant, wherein the polymer is crosslinked during film formation. The sterically hindered alkoxylated silane monomer has the structure R'--Si--(OR.sup.2).sub.n (R.sup.3).sub.3-n wherein R.sup.1 is selected from the group consisting of an alkylene, arylene, and aralkylene group; R.sup.2 is independently a sterically hindered alkyl group having 3 to 10 carbon atoms in a straight or branched chain configuration; R.sup.3 is a monovalent alkyl group having 1 to 10 carbon atoms; and n is an integer of from 1 to 3.
