High solids content CB coating

摘要

Disclosed is a coating composition for producing a high solids content carboxymethylcellulose based "CB" coating for use in pressure sensitive carbonless copy systems. The formulation comprises carboxylmethylcellulose, a wall-forming carboxylated acrylic resin, an organic cross-linker, a polyvalent metal salt, and an oil containing color-forming dye. The composition has a solids content of at lesat 30% and a viscosity within the range of 50 to 5000 centiposes. The CB paper exhibits the ability to produce improved imaging on computer and dot matrix printers because of better release efficiency and may be manufactured using less energy.
