Abstract: Dyes are transferred from a substrate to an acceptor by sublimation or vaporization of the dye by means of a thermal printing head by using a substrate on which there is situated cationic dyes having a cyanine chromophore and one or more N-H groups which are part of the cyanine chromophore, in their electrically neutral form as the result of deprotonation at the N-H group and transferring these deprotonated dyes to a coated paper.
