PURPOSE:To obtain a large number of copy images at low cost in an easy process, by using a diazo type heat transferring master capable of forming a subimable dye image. CONSTITUTION:A heat transferring layer consists of 10-80wt% diazo compd., such as 4-diazo-1-dimethylaminobenzene; 10-80wt% coupling component, such as resorcinol; 10-60wt% hot melt material, such as lauramide, palmitohydrazide, or polyethyleneglycol monostearate; and further, heat transfer accelerator, binder, pigment, antioxidant, etc., and this layer is formed on a support. An original is overlaid on this heat transferring layer and exposed to light. This is developed to form a sublimable dye image, and this master is heated with a heating drum or the like to transfer the dye image to a transfer sheet of paper, resin film, or the like attached to the master. |
