Abstract (en)
[origin: EP0235939A2] A thermal transfer printing sheet comprising a substrate having a coating comprising a dye of the formula: A - N = N- E wherein A is a phenyl group substituted by at least one electron-withdrawing group selected from NO2, CN, CF3, halogen, -SO2-C1-4-alkyl, -SO2F, -SO2CF3, -SO2NRR<1>, -CONRR<1>, -COOR, -CO-CO-R, wherein R and R<1> are independently selected from H and C1-4 alkyl, provided that where A carries only two halogen atoms these are not in the 2- and 6- positions in relation to the azo link; and E is the radical of an aniline, a tetrahydroquinoline, a lilolidine or a julolidine coupling component, and a thermal transfer printing process for the coloration of a polymeric substrate using the thermal transfer printing sheet.
