Appeal No. 1997-1053
Application No. 08/432,291
APPENDIX
1. A process which comprises (a) providing a
migration imaging member comprising (1) a
substrate, (2) an infrared or red light
radiation sensitive layer comprising a pigment
predominantly sensitive to infrared or red
light radiation, and (3) a softenable layer
comprising a softenable material, a charge
transport material, and a photosensitive
migration marking material predominantly
sensitive to radiation at a wavelength other
than that to which the infrared or red light
sensitive pigment is predominantly sensitive;
(b) uniformly charging the imaging member; (c)
subsequent to step (b), uniformly exposing the
charged imaging member to a source of activating
radiation with a wavelength to which the
migration marking material is sensitive,
wherein a filter comprising the infrared or
red light radiation
sensitive pigment is situated between the radiation
source and the imaging member; (d) subsequent to
step (b), exposing the imaging member to infrared
or red light radiation at a wavelength to which
the infrared or red light radiation sensitive pigment
is sensitive in an imagewise pattern, thereby
forming an electrostatic latent image on the
imaging member; and (e) subsequent to steps (c)
and (d), causing the softenable material to soften,
thereby enabling the migration marking material to
migrate through the softenable material toward
the substrate in an imagewise pattern.
