摘要：
Azo dyes are transferred from a substrate to a plastic-coated paper by diffusion with the aid of a thermal printing head, these azo dyes having the formula ##STR1## where D is the radical of a diazo component andR.sup.1, R.sup.2 and R.sup.3 are each independently of the others hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted phenyl or substituted or unsubstituted cyclohexyl andR.sup.4 is alkyl.
