Abstract
Procedure for obtaining a set of tracing, of the type made up of at least two sheets, which on the faces that touch each other, are each provided with a layer containing a previous product of organic colorant, that upon contact with an acidic reaction material provides a color reaction, and of another layer containing the acidic reaction material, characterized in that the previous product of organic colorant is dispersed in a binder and the mixture is applied on the receptor layer writing on the upper side of the lower sheet so that the previous dye product is fixedly bound with the support material and because the acid reaction product is embedded in a binder and applied on the lower side of the upper sheet as a fully transmissible coating entirely under the pressure of writing.
