Abstract:
A method of forming a printed pattern on a substrate includes printing a pattern onto the substrate with a conductive ink including a conductive material, a thermoplastic binder and a solvent, curing the printed pattern, and fusing the printed pattern by feeding the printed pattern through a fusing system operated at a temperature of about 20° C. to about 130° C. above the glass transition temperature of the thermoplastic binder and at least 120° C. at a minimum, a pressure of from about 50 psi to about 1500 psi, and a feed rate through the fusing system of about 1 m/min to about 100 m/min. The method may be done continuously. The method improves the sheet resistivity of the printed ink.

Abstract:
An intermediate transfer member containing a blend of materials including a base polymer and a stimulus-responsive additive, an intermediate transfer member containing a first layer including a base polymer and a second layer grafted onto the first layer and including a stimulus-responsive additive, and a method of printing an image to a substrate.
Abstract:
Described herein is a transfer member for use in aqueous ink jet printer. The transfer member includes a surface layer of a cross-linked polydiphenylsiloxane network formed from a silanol terminated dialkylsiloxane-diphenylsiloxane copolymer and a trialkoxy- or trihydroxysilane terminated polydialkylsiloxane. The diphenylsiloxane moieties are from about 5 weight percent to about 80 weight percent of the network. The trialkoxy- or trihydroxysilane terminated polydialkylsiloxane are from about 1 weight percent to about 60 weight percent of the network. All silane molecules are bonded together via silicon oxide (Si—O—Si) linkages in a single system. The network is insoluble in solvents selected from the group consisting of: ketones, chlorinated solvents and ethers.
Abstract:
A phase change ink composition comprising an amorphous component, a crystalline material, a photochromic material and optionally, a colorant, which are suitable for ink jet printing, including printing on coated paper substrates. The novel phase change ink formulation allows the ink to change color when exposed to UV light, reversibly and multiple times, providing an ink suitable for use in security applications.
