ABSTRACT:
Provided are polymers having the formula: ##STR1## wherein R.sup.1 is an aromatic group having from 6 to 10 carbon atoms, R.sup.3 is a fatty alkyl group having from 12 to 22 carbon atoms, and R.sup.5 is a hardening alkyl group having from 1 to 4 carbon atoms, R.sup.2, R.sup.4, and R.sup.6 are each independently hydrogen or methyl, and y, is chosen in relation to x and z such that a film of said polymer has improved alkali resistance. Also provided is a method of coating a substrate comprising (i) contacting a surface of a substrate with an aqueous dispersion composition comprising a polymer as defined above, and (ii) drying said surface to form a film of said polymer in contact with said surface. In preferred methods, said polymer in aqueous dispersion is supplied to said surface by a hydrophilic cylindrical transfer roll. These polymers are particularly useful as the binder for an ink composition, or an overprint varnish, having good alkali resistance.
