摘要

A process for producing a sheet of paper for use as paper for multiple copies or paper for copies of a single use, process comprising distributing finely divided particles of material, especially a resin based on polyvinyl chloride, in a volatile organic liquid, in which a dye or a material capable of dyeing the polymer is dissolved, in such a way that the particles swell, and apply the resulting homogeneous distribution of swollen particles as a layer donor on a support layer, either directly or after of an adequate dilution, the layer being dried by evaporation of the organic liquid in order to produce a substantially uniform layer of finely dispersed and mutually adherent particles.
