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,),(R,),wherein R,is selected from the group consisting of an alkylene, arylene, and aralkylene group; R,is independently a sterically hindered alkyl group having 3 to 10 carbon atoms in a straight or branched chain configuration; R,is a monovalent alkyl group having 1 to 10 carbon atoms; and n is an integer of from 1 to 3.
