Abstract:
Thermo-transfer ribbon with a carrier, a first thermo-transferable layer formed on one side of the carrier and a second thermo-transferable layer, formed on the first thermo-transferable layer, whereini) the first thermo-transferable layer contains a luminescent pigment, wax(es) having a melting point of approximately 70 to 110Â° C. and approximately 1-22% by weight of a polymer wax plasticizer having a glass transition temperature Tg of âˆ’20 to +10Â° C., ii) the second thermo-transferable layer contains a non-luminescent pigment, a wax-compatible polymer binding agent and approximately 5 to 30% by weight of wax, iii) the second thermo-transferable layer has a melting enthalpy DH of approximately 10 to 80 J/g, and iv) in the remission spectrum of the non-luminescent pigment, in the wave length range of the light emitted by the luminescent pigment there is a remission maximum or an ascending flank of the remission.
