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 transpar-ent 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.

IMPROVED TRANSPARENCY FOR Proposed Classification

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 transpar-
ent 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 coating a transparent thermoplastic
film sheet with a non-volatile natural or synthetic wax having
a melting point above 40°C, that an improved transparency
results when the image is formed by colored toner particles.
Typical waxes would include ouricury, carnuba, montan, german
wax, palm wax, and ozokerite. Various micro-crystalline waxes
and micro-ceresine waxes may also be used, Specifically,
adhesion of the multicolored image is improved, thus permit-
ting reproduction of colors and color densities in the pro-
jected image which correspond to the multicolored original
copied.
