摘要:
A magnetic recording element comprises a polymeric film substrate on which is formed a thin CoNi recording layer. Over the latter is a protective layer of an acrylic copolymer of a perfluoroalkyl methanol ester of acrylic or methacrylic acid, preferably formed by plasma polymerization. The layer is tough, has a low coefficient of friction and protects the magnetic layer against corrosion.
摘要:
Printing images on an intermediate member by jetting conductive ink containing a fluid and marking particles in an image-wise fashion onto an intermediate member. The ink is concentrated by application of radio frequency (RF) energy, focused on the ink image to remove a substantial portion of the fluid. The concentrated ink marking particle image, is then transferred to a receiver.
摘要:
Thermographic and photothermographic materials comprise a barrier layer to provide physical protection and to prevent migration of diffusible imaging components and by-products resulting from high temperature development. The barrier layer comprises a film-forming, water-insoluble aromatic polyester that has a molecular weight of at least 10,000 g/mole and is capable of retarding diffusion of mobile chemicals such as fatty acids, developers and toners. This polymer can also be present in admixture with another film-forming polymer to provide a clear and scratch-resistance surface.

An improved reusable multiactive electrophotographic element has a charge-transport layer comprising a triarylamine charge-transport material in a binder comprising a polyester containing recurring units having the structure ##STR1##
摘要:
A thermally-transferred color filter array element comprising a transparent support having thereon a thermally-transferred image comprising a repeating pattern in a binder of colorants composed of one or more polyesters having Tg greater than about 200.degree. C. derived from one or more dibasic aromatic acids and one or more dihydroxy-phenols that contain at least one large bulky central moiety.
摘要:
New crosslinked polymers are prepared from a combination of starting materials comprising a polymer, a crosslinking agent for the polymer, and a conductivity agent containing a quaternary ammonium moiety. The conductivity agent contains at least one functional group which, during an otherwise typical process of crosslinking the polymer through the crosslinking agent, reacts to bond the conductivity agent covalently and pendently to the crosslinking agent or the polymer. The resultant crosslinked polymer has lower electrical resistivity due to inclusion of the conductivity agent.
摘要:
An imaging composition and element are disclosed wherein an aromatic dialdehyde reacts with amines generated in response to activating radiation. Improved binders are used to insure sufficient retention of the volatile dialdehyde prior to imaging.
摘要:
A thermal, non-silver halide-containing image receiver element includes a support and an aqueous-coated image receiving layer. This receiving layer comprises a water-dispersible polymer having a polyurea or polyurethane backbone and up to 25 weight % of the water-dispersible polymer comprising polysiloxane side chains that are covalently attached to the backbone, each of the side chains having a molecular weight of at least 500. Aqueous dispersions of polyester ionomers and crosslinking agents can also be present.
