Abstract

In pressure-sensitive copying papers, the undesirable color- formation occurring upon contact between color-forming layer and color-developing layer can be prevented by incorporating, into the color-forming layer of microcapsules containing a color-forming dye, fine polyolefin particles having a greater size than the microcapsules.
