Abstract

Improvements in the manufacture of color-forming adsorbent sheets for pressure-sensitive copying paper, characterized in that the sheet comprises a support that has two layers applied, containing one of said layers adjacent to the support, a binder, and from 0 to 500 parts by weight, based on the binder, of an adsorbent substance, and the other layer containing an adsorbent substance and from 0 to 20 parts by weight, based on the adsorbent substance, of a binder, said adsorbent substance being capable of forming a distinguishable color when it comes in contact with a colorless former.
