In the prepn. of a pressure-sensitive, carbon-free transfer system, at least one surface of a paper substrate is (partly) coated, by wet or dry offset printing, with a non-aq., solvent free coating contg. microcapsules contg. a dye precursor. A pressure-sensitive, carbon-free carbon paper system is claimed. The coated paper does not have to be freed from solvent or water. The paper can be made in 1 process on a multi-colour offset printing machine. There are no special requirements for the paper carrier. |
