Abstract (en)

[origin: EP0439200A1] A process for the transfer of bichromophoric methine dyes from a carrier to paper coated with plastic with the aid of an energy source, in which a carrier is used on which are situated one or more dyes of the formula <IMAGE> in which   L represents a bridging member which does not permit any conjugation of pi -electrons between the radicals Z and Y,   X denotes cyano, C1-C6-alkoxycarbonyl or C1-C6-monoalkylcarbamoyl, where the alkyl groups can be interrupted by oxygen atoms, C5-C7-cycloalkoxycarbonyl, C5-C7-monocycloalkylcarbamoyl, phenoxycarbonyl, or monophenylcarbamoyl and   Y and Z independently of one another denote an optionally benzo-fused aminophenylene radical or a heterocyclic radical.
