Abstract

Procedure for the manufacture of a paper for multi-copying with color acceptor properties whose color acceptors together with chromogenic precursors allow the color to be formed, characterized in that during the preparation of the material, a coating of the fibers is carried out with hydrated colloidal clays as color and thereafter - eventually adding uncoated fibers, pigment-shaped color acceptors and other additives to the paper material - the paper with color-accepting properties is dewatered in the papermaking machine and then it dries you.
