Abstract
Disclosed is a pressure sensitive manifold paper prepared by coating a substrate with a coating composition containing microcapsules of polyurethane resin or polyurea resin wall film and drying the resulting coating, the pressure sensitive manifold paper being characterized in that a latex of copolymer of comonomers comprising about 10 to about 50% by weight of styrene, about 15 to about 55% by weight of butadiene, about 10 to about 40% by weight of methyl methacrylate and up to about 15% by weight of acrylonitrile is incorporated in the coating composition in an amount of about 5 to about 30% by weight (calculated as solids) based on the microcapsules (calculated as solids). The pressure sensitive manifold paper has an adequate balance between the color forming ability and susceptibility to color smudges due to contact or friction.
