Abstract
Abstract Disclosed is a process which comprises providing an imaging apparatus equipped with a path for moving receiver sheets through the apparatus and having infrared sensors situated along said path, incorporating into the imaging apparatus a substantially transparent receiver sheet having coated on at least a portion thereof an infrared absorbing material contained in a polymeric binder, passing the substantially transparent receiver sheet along the path, wherein the infrared sensors detect the presence of the infrared absorbing material on the substantially transparent receiver sheet, and generating an image on the substantially transparent receiver sheet. This process enables the use of substantially transparent receiver sheets in imaging apparatuses employing optical sensors or detectors for locating and/or positioning receiver sheets in the apparatus without the need for opaque strips on the transparencies or separate opaque sheets attached to the transparencies.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
91 words
A process which comprises providing an imaging apparatus equipped with a path for moving receiver sheets through the apparatus and having infrared sensors situated along said path, incorporating into the imaging apparatus a substantially transparent receiver sheet having coated on at least a portion thereof an infrared absorbing material contained in a polymeric binder, passing the substantially transparent receiver sheet along the path, wherein the infrared sensors detect the presence of the infrared absorbing material on the substantially transparent receiver sheet, and generating an image on the substantially transparent receiver sheet.
Claim 2
Dependent Claim
91 words
A process which comprises providing an imaging apparatus equipped with a path for moving receiver sheets through the apparatus and having infrared sensors situated along said path, incorporating into the imaging apparatus a substantially transparent receiver sheet having coated on at least a portion thereof an infrared absorbing material contained in a polymeric binder, passing the substantially transparent receiver sheet along the path, wherein the infrared sensors detect the presence of the infrared absorbing material on the substantially transparent receiver sheet, and generating an image on the substantially transparent receiver sheet.
Claim 3
Dependent Claim
48 words
A process according to claim 1 wherein the infrared absorbing material and polymeric binder are present in relative amounts of from about 5 to about 25 parts by weight of the infrared absorbing material and from about 0.05 to about 2 parts by weight of the polymeric binder.
Claim 4
Dependent Claim
14 words
A process according to claim 1 wherein the infrared absorbing material is a dye.
Claim 5
Dependent Claim
34 words
A process according to claim 1 wherein the polymeric binder is selected from the group consisting of methyl methacrylate polymers, methyl methacrylate copolymers, ethyl methacrylate polymers, ethyl methacrylate copolymers, styrene/diolefin copolymers, and mixtures thereof.
Claim 6
Dependent Claim
33 words
A process according to claim 1 wherein the polymeric binder and infrared absorbing material are coated onto the substantially transparent receiver sheet in a thickness of from about 2 to about 10 microns.
Claim 7
Dependent Claim
26 words
A process according to claim 1 wherein the infrared sensors have output sources in the light wavelength range of from about 600 to about 1,000 nanometers.
Claim 8
Dependent Claim
15 words
A process according to claim 1 wherein the imaging apparatus is an electrophotographic imaging apparatus.
Claim 9
Dependent Claim
16 words
A process according to claim 1 wherein the imaging apparatus is an ink jet printing apparatus.
Claim 10
Dependent Claim
20 words
A process according to claim 1 wherein the substantially transparent receiver sheet comprises a substrate and an ink receptive coating.
Claim 11
Dependent Claim
27 words
A process according to claim 9 wherein the coating of the infrared absorbing material and polymeric binder is situated on the surface of the ink receptive coating.
Claim 12
Dependent Claim
33 words
A process according to claim 9 wherein the coating of the infrared absorbing material and polymeric binder is situated on the surface of the substrate opposite to that containing the ink receptive coating.
Claim 13
Dependent Claim
27 words
A process according to claim 9 wherein the coating of the infrared absorbing material and polymeric binder is situated between the substrate and the ink receptive coating.
Claim 14
Dependent Claim
53 words
A process according to claim 1 wherein the coating of the infrared absorbing material and polymeric binder is situated in substantially the same location on each edge of the substantially transparent receiver sheet, thereby enabling the receiver sheet to be detected by the infrared sensors when fed through the apparatus in any orientation.
Claim 15
Dependent Claim
49 words
A process according to claim 1 wherein the coating of the infrared absorbing material and polymeric binder is situated on the substantially transparent receiver sheet in an encoded pattern and the imaging apparatus decodes the information contained in the pattern and employs said information to control the imaging process.
