Abstract

In laser transfer printing whereby a photon energy source, such as that emitting from a laser, is employed to provide transfer of a heat sensitive formulation contained on a transparent substrate, it is preferred to have the highest transferred print density possible from the minimum amount of energy emitting from the laser source.

Thermally Sensitive Ribbon for Laser Transfer Printing

In laser transfer printing whereby a photon energy source, such as that emitting from a laser, is employed to provide transfer of a heat sensitive formulation contained on a transparent substrate, it is preferred to have the highest transferred print density possible from the minimum amount of energy emitting from the laser source.

It has been discovered that the very high densities can be obtained by incorporating into the formulation crystal violet dye. This violet color is not as pleasing as a black color for printing. To overcome this factor, this dye is combined with other dyes to give a black image.

One such formulation contains crystal violet, toluidine blue 0, Sublaprint Orange (manufactured by L. B. Holliday), carbon black and cellulose nitrate. By adjusting the dye ratios, black print with high-optical density at 0.1 J/cm/2/ of laser energy is obtained.
