Abstract

"METHOD FOR MANUFACTURING A THERMOSENSIVE COPYING MATERIAL" consisting of a sheet-shaped substrate on one of whose surfaces a first layer of a first binder material has been applied as a coating in which at least one organic sulfonic acid has been incorporated, and immediately above or below this first layer, a second layer of a second binder material in which at least one chromogenic compound has been incorporated, the material of the first or second layer closest to the substrate being insoluble in the solvent liquid of the binder of the other layer and reacting the sulfonic acid with the chromogenic compound to produce a color mark in response to the application of heat to the copy material.
