A procedure improved to manufacture a transparent, heat-resistant recommended sheet intended to form colored images resistant to discoloration. (Machine-translation by Google Translate, not legally binding)
An improved process for manufacturing a transparent, heat-resistant receptor sheet for forming colored images resistant to discoloration by a process involving heat-induced transfer of salicylic acid vapors to said receptor sheet in image areas, comprising improving the the method provides a thin, acid-reactive coating on a thin, transparent, heat-resistant carrier film, wherein said acid-reactive coating consists essentially of one part by weight of the dye-forming color precursor, chromogen, capable of absorbing protons, in solution in about 15 to 45 parts, of neutral film-forming polymer based on monomers that include about 75% to 95% vinyl chloride.
