20080220190AQUEOUS SUBBING FOR EXTRUDED THERMAL DYE RECEIVER - The present invention relates to an image recording element comprising a support having thereon an aqueous subbing layer and an extruded dye receiving layer, wherein the image recording element is a thermal dye receiver. The present invention also relates to a method of making a thermal dye receiving element comprising providing a support for an imaging element; applying an aqueous subbing layer to the support; and extruding thereon at least one thermal dye receiving layer.09-11-2008
20090050855POLYMERIC CONDUCTOR DONOR AND TRANSFER METHOD - The present invention relates to a donor laminate for transfer of a conductive layer comprising at least one electronically conductive polymer on to a receiver, wherein the receiver is a component of a device. The present invention also relates to methods pertinent to such transfers.02-26-2009
20090176111AZINIUM SALTS AS SPLAYANT FOR LAYERED MATERIALS - The present invention relates to a splayant, that is, an intercalant/exfoliant, comprising an azinium compound capable of splaying a layered material.07-09-2009
20100013874CONTROLLED GAP STATES FOR LIQUID CRYSTAL DISPLAYS - The present invention relates to a bistable matrix-addressable display element comprising a substrate, a bistable electrically modulated imaging layer having a reflection maximum, at least one conductor, and at least one field-spreading layer between said bistable electrically modulated imaging layer and said at least one conductor, wherein said field-spreading layer has a sheet resistance (SER) of less than 1001-21-2010
20100118243POLYMERIC CONDUCTIVE DONOR AND TRANSFER METHOD - A donor laminate for transfer of a conductive layer has a transparent substrate and a conductive layer comprising at least one electronically conductive polymer that is present in an amount of at least 40 weight %, a polyanion, and inorganic particles having an average particle size of less than 100 nanometers (nanoparticles). This donor laminate can be used to transfer the conductive layer to a suitable receiver element to prepare various electronic devices.05-13-2010
20100220074TOUCHSCREEN WITH CARBON NANOTUBE CONDUCTIVE LAYERS - The present invention is directed to a touchscreen comprising touch side electrode and device side electrode wherein each electrode comprises an insulating substrate and an exposed electrically conductive layer, wherein said exposed electrically conductive layers are adjacent and separated by dielectric spacers, and wherein only one of the exposed electrically conductive layers comprises carbon nanotubes.09-02-2010
20110027505IMAGE RECEIVER ELEMENTS WITH AQUEOUS DYE RECEIVING LAYER - 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.02-03-2011
20110052843IMAGE RECEIVER ELEMENTS - An image receiving element is a composite of multiple layers on a support including, in order, an extruded compliant layer, an aqueous-coated subbing layer, and an image receiving layer that may also be extruded. The extruded compliant layer is non-voided and comprises from about 10 to about 40 weight % of at least one elastomeric polymer. This image receiving element can be disposed on a support to form a thermal dye transfer receiver element, an electrophotographic image receiver element, or a thermal wax receiver element. Excellent adhesion is provided between the extruded compliant layer and the image receiving layer by means of the aqueous-coated subbing layer.03-03-2011
20110091667THERMAL DYE IMAGE RECEIVER ELEMENTS - A thermal dye image receiver element has, in order, a cellulosic raw base support, an antistatic subbing layer, and a thermal dye receiving layer. The cellulosic raw base support has an internal electrical resistance (WER) that is at least 1 log ohm/square greater than the surface electrical resistance (SER) of the antistatic subbing layer. This arrangement of antistatic properties overcomes a static problem in the thermal dye image receiver elements by properly balancing the conductivity between the two antistatic locations.04-21-2011
20110117299IMAGE RECEIVER ELEMENTS - An image receiver element includes a water-soluble or water-dispersible polyurethane binder in the image receiving layer. This polyurethane has a T05-19-2011
