Abstract

A pressure sensitive copying system having compara­ tively uniform thickness and resistant to smudging, which is suitable for spot-coated copying sheets such as chit is obtained by disposing a color forming components layer on the layer of a microcapsule protective agent which has been provided all over the paper sheet, at least one of the compo­ nents being enclosed in microcapsules.
