Abstract (en)
[origin: EP0304206A2] 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.
