Process for transferring dyes from a support to an acceptor by sublimation or evaporation of the dyes with the aid of a thermal head, using a support on which cationic dyes with cyanine chromophore, which have at least one NH group, which is part of the cyanine chromophore, are in their electrically neutral form deprotonated on the NH group and transfers these deprotonated dyes to a coated paper. |
