摘要：
Paper having improved printability in rotogravure printing is provided by coating a paper substrate with an aqueous coating formulation containing a pigment such as kaolin clay, a binder such as a styrene/butadiene/itaconic acid terpolymer and a polyamidoamine such as the reaction product derived from ethylene diamine and methylacrylate.
