[origin: EP0141856A1] Pressure-sensitive copying paper comprising a support having coated thereon a layer containing microcapsules retaining a color former, or a colorless dye, capable of reacting with a color developer to form color, said layer further containing both fine cellulose powder and fatty acid amide. The cellulose powder and the amide are remarkably effective in preventing smudge of the copying paper.
