Abstract
A transfer material and method of use for transferring monochrome and full colour images produced by a xerographic process or dry toner printing onto a substrate. The process requires the use of film form polymethylpentene material as the transfer material which is used to transfer the xerographic or dry toner image onto the substrate with the application of heat and pressure.
Claims20
A method of transferring an image to a substrate, the method comprising:
- (a) with an image forming apparatus that prints toner images, printing a toner image on a surface of an image carrier, the surface of the image carrier comprising polymethylpentene material;
- (b) discharging the image carrier with the image printed thereon from the image forming apparatus;
- (c) placing the image carrier against a surface of the substrate with the toner image between the image carrier and the substrate, the surface of the substrate having a greater affinity for the toner than the image carrier when the toner is heated;
- (d) heating the image carrier and the substrate, with the toner image therebetween, under pressure;
- (e) thereafter removing the image carrier from the substrate, with the toner image transferred to the substrate.

A method of transferring an image to a substrate, the method comprising:
- (a) with an image forming apparatus that prints toner images, printing a toner image on a surface of a first image carrier to provide a toner image on the first image carrier, the surface of the first image carrier comprising polymethylpentene material;
- (b) discharging the image carrier with the image printed thereon from the image forming apparatus;
- (c) placing the surface of the first image carrier against a surface of a second image carrier with the toner image between the first image carrier and the second image carrier, the second image carrier having a greater affinity for the toner than the first image carrier when the toner is heated;
- (d) then heating the first and second image carriers, with the toner image therebetween, under pressure;
- (e) thereafter removing the first image carrier from the second image carrier, with the toner image transferred to the second image carrier;
- (f) placing the second image carrier against a surface of the substrate with the toner image therebetween, the surface of the substrate having a greater affinity for the toner than the second image carrier;
- (g) then heating the second image carrier and the substrate, with the toner image therebetween, under pressure;
- and
- (h) thereafter removing the second image carrier from the substrate, with the toner image transferred to the substrate.
