Abstract

Imaged transparencies used in the projection of an image onto a surface to be viewed can be prepared xerographically in a standard Xerox 6500 color copier by simply imaging a trans-parent thermoplastic film sheet in the same manner that a copy paper is used to receive a toner developed latent image. Upon fixing the powder image to the transparency, the transparency is then capable of being used with a projection apparatus to project the fixed powder image onto a viewing surface.

Imaged transparencies used in the projection of an image onto
a surface to be viewed can be prepared xerographically in a
standard Xerox 6500 color copier by simply imaging a trans-
parent thermoplastic film sheet in the same manner that a copy
paper is used to receive a toner developed latent image. Upon
fixing the powder image to the transparency, the transparency
is then capable of being used with a projection apparatus to
project the fixed powder image onto a viewing surface.

It has been found that by treating a thermoplastic film sheet
with an organic sulfonic acid compound, as by immersion, that
an improved transparency results when the image is formed by
colored toner particles. Specifically, adhesion of the multi-
colored image is improved, thus permitting reproduction of
colors and color densities in the projected image which corre-
spond better to the, multicolored original copied.
