ABSTRACT:
A transfer sheet of a transfer sheet assembly for use in an Autographic Register System has a coating which embodies a colorless color former. The coating is porous and the colorless color former is retained in the pores of the coating until autographic writing is applied to the uppermost record web of the assembly whereby the colorless color former is squeezed out of the coating onto the upper face of the next record web of the assembly. The record webs of the assembly have a developing receptive nature to develop the color of the squeezed out color former. The area of development corresponds to the autographic writing applied to the uppermost sheet.
