    (54) Self-contained pressure-sensitive carbonless recording sheet having anti-scuff protective overcoating


    (57) A protective overcoat is provided for a self-contained pressure-sensitive carbonless recording sheet. The sheet is initially coated with a blend of a microencapsulated color former and a color developer in a binder medium. The purpose of the overcoat is to prevent premature color formation through acci­dental rupture of the microcapsules and reaction of the color former and color developer. The overcoat comprises essentially an aqueous-based film forming material; suitable materials include: synthetic latex, polyvinylalcohol and polyvinyl alcohol-acetate copolymers, cellulose gums and ethers, acrylic resins, polyethylene oxide ethers, polyvinylpyrrolidone and copolymers of styrene, ethylene and methylvinylether with maleic anhydride.
