Procedure

A cross-linked polymeric leveling agent was prepared by mixing butyl acrylate (“BA”,40 wt %), acrylic acid (“AA”,10 wt %), vinyl imidazole (“VI”,40 wt %), trimethylolpropane triacrylate (“TMPTA”, l0 wt %) and a peroxide initiator (tert-amyl peroxypivalate) in a vessel cooled in an ice bath. The mixture was then pumped into a heated reactor containing iso-propanol alcohol as solvent. The reaction was controlled at 80° C. for approximately 2 hours. The iso-propanol alcohol was then removed by vacuum evaporation and the product was washed with water to provide an approximately 33% aqueous solution of a cross-linked polymer (BA/AA/VI/TMPTA) having an approximate weight average molecular weight (“Mw”) of 77,000, based on gel permeation chromatography against appropriate standards, and a number average molecular weight (“Mn”) of 1400.
