Liquid developers and processes thereof

A process for flashless hot melt bonding of seamed flexible belts having a substrate and a seam having interlocking seam members, wherein the interlocking seam members are held together by an adhesive for use in electrostatographic, contact electrostatic, digital and other like machines, wherein the process includes: a) providing a release layer having an adhesive strip on a front side of the release layer, wherein the release layer is wider than the adhesive strip; b) providing the release layer containing the adhesive strip over the seam, wherein the front side of the release layer containing the adhesive strip is in contact with the seam and mutually mating members; c) thermal compressive adhesive bonding of the release layer to the seam, and d) optionally postcuring the seam; and wherein virtually no flashing of the adhesive outside the seam occurs.

A method of making a low surface energy material such as a fuser member comprising providing a shaped fluoroelastomer, preparing a solvent solution of a polyorganosiloxane having reactive functionality and the formula: ##STR1## where R is an alkyl, alkenyl or aryl group having less than 19 carbon atoms or an aryl group substituted with an alkyl or alkenyl group having less than 19 carbon atoms, the functional group A is epoxy, vinyl, acrylic, allylic or methacrylic and n is 2 to 350, contacting the fluoroelastomer with the solution to form at least a thin coating of the polyorganosiloxane on said fluoroelastomer and exposing the coated fluoroelastomer to a level of radiation to form a thin surface layer of the polyorganosiloxane grafted to said fluoroelastomer.

Radiation induced grafting of polyorganosiloxanes to fluoroelastomers

A fuser member comprising a supporting substrate having an outer layer of a cured fluoroelastomer and having a thin surface layer of a polyorganosiloxane having been grafted to the surface of said cured fluoroelastomer in the presence of a dehydrofluorination agent for the fluoroelastomer and from a polyorganosiloxane having reactive functionality and the formula: ##STR1## where R is an alkyl, alkenyl or aryl group having less than 19 carbon atoms or an aryl group substituted with an alkyl or alkenyl group having less than 19 carbon atoms, the functional group A is hydrogen, hydroxy, alkoxy, amino, epoxy, vinyl, acrylic or mercapto, and n is 2 to 350.

A toner composition comprised of resin particles selected from the group consisting of a semicrystalline polyolefin and copolymers thereof which a melting point of from about 50.degree. C. to about 100.degree. C., and pigment particles.

Toner and developer compositions with semicrystalline polyolefin resins

A method for selectively hardening and toughening the bulk mass of predetermined portions of a polymeric structure which includes the steps of contacting the polymeric structure with a multifunctional monomer to diffuse the monomer into the polymeric structure and irradiating the predetermined portions of the polymeric structure with activating radiation to cause the bulk polymeric material at those portions to be hardened and toughened. In a preferred embodiment the character fonts of a print wheel made from nylon 66 are contacted with a multifunctional monomer which is subsequently exposed to electron beam radiation whereby a structural network of monomer or monomer reactive with polymer or mixtures is formed.

Selectively altering the bulk properties of polymer structures

An optically isotropic device or component made of an optically isotropic polymeric material which is a blend of two completely miscible polymers which have opposite optical anisotropies. The blend has zero birefringence which is not substantially affected by processing of the blend into the optical device or component.

Optically isotropic devices

Process for enhancement in the mechanical properties of polymeric films prepared from photoconductive polymers, such as poly(N-vinylcarbazole), its homologues and/or its analogues. In this process, polymeric films of these materials are subjected to strain-induced orientation whereby the polymeric chains contained therein are aligned parallel to the lines of force imparted to the film. In order to prevent accompanying deterioration of the charge carrier transport properties of the polymer during such orientation process, the film is subjected to a disordering strain either concurrent with or subsequent to such orientation in order to relax the spatial constraints on their bulky, pendant photoactive groups, and thus relieve them of the distortion imparted during such orientation. Films prepared according to this process have improved flexibility and reduced brittleness, thus making such materials highly suitable for use in flexible electrophotographic imaging members.
