Carbon paper with transfer regions having different colours - is used to transfer indicia onto underlying and-or overlying papers to give different distribution of colours respectively

摘要

Carbon paper for transfer of indicia onto an underlaid or overlaid paper has different regions (A, B, C, D, E, F) where the transferrable surface layers are of different colours. In this way the transferred indicia can have the colour required of them for selected regions of the receptor paper. The carbon paper may have different colours at the opposite sides of the sheet. On the other hand the front of the sheet may have regions (ob(Y)) which are waxed and are of white colour while the corresponding rear surface has a coloured carbon layer.
