摘要： Heat activated duplicating process involving the steps of forming a coating on localized areas of a master sheet by transfer thereto from a transfer sheet, the coating being in the form of a discontinuous layer containing light colored normally stably solid, vaporizable first reactive material together with a particulate material and a minor amount of binder, placing the master sheet against a first receptor copy sheet which contains a second reactant material which coreacts with said first reactant to form a visible image, and subjecting the combined sheets to heat to vapor transfer a portion of the first reactant material, whereby an image is formed on the copy sheet, and repeating the heating step with additional receptor copy sheets to form additional copies.
