  • Electrostatographic method for the production of transfer images
    Patent number: 5985503
    Abstract: A process for electrostatographic production of a transfer image on a transfer foil, useful for hot-stamping is disclosed. The process uses transfer foils with a thickness between 5 and 60 .mu.m and the image is printed on the transfer foil using toner particles with a melt viscosity between 100 and 2,000 Pa.multidot.s. The image is preferably fixed to the transfer foil by non-contact fusing methods and the printing proceeds on a web unwound from a roll.
