Zusammenfassung:PURPOSE:To improve color forming properties, resistance to contact stains, resistance to rubbing stains, and resistance to printing stains by incorporating a specific synthetic polymer latex in a coating liquid. CONSTITUTION:In a coating liquid, a synthetic polymer latex composed of 45-79.5wt.% aliphatic conjugated diolefin monomer, 5.5-15wt.% ethylene unsatd. acid monomer, 15-40wt.% ethylene unsatd. nitryl monomer, and 0-20wt.% ethylene unsatd. acid amide monomer is incorporated. Therefore, the strength characteristics of the synthetic polymer wall film and the flexibility of the latex favorably interact with each other. In this manner, pressure-sensitive copy paper is made available with satisfactory color forming properties, minimum color forming stain caused by contact, rubbing, or the like, and with superior printability.
