    摘要: A carbonless paper produced by using, as leuco dye solution-containing microcapsules, synthetic high molecular wall membrane microcapsules and, as a color developing agent, an inorganic solid acid gives smooth printing when used in letter printers. This paper has various advantages in printing by letter printers such as no attack for photosensitive plates or masters, no generation of offensive smells or fumes at the time of thermal fixation and no destruction of microcapsules in wet development.

    摘要: There is disclosed no-carbon copying paper composed fundamentally of a color former sheet produced by coating a support with microcapsules containing a colorless electron-donative organic compound as a color former and a color developer sheet produced by coating a support with a coating color containing activated clay as a color developer which adsorbs the aforesaid electron-donative organic compound to develop color. When said coating color is prepared by adding a polyvinyl alcohol, a styrene-butadiene latex and a wax emulsion to the activated clay, it becomes possible to apply it at a high concentration and there are accomplished the maintenance of surface strength of the color developer sheet, the decrease in stains on the blanket and the improvement in sunlight resistance of the colored characters and in the aptitude for pasting.
