Substantially transparent electrodes are formed upon a substrate by forming on the substrate, in order, a high index layer, a metallic conductive layer, and a conductive or semi-conductive top layer; and patterning the top layer and the conductive layer, preferably by laser ablation, to form a plurality of discrete electrodes from the metallic conductive layer. Conductors can be attached directly to the top layer, without requiring removal of this layer to expose the metallic conductive layer. The high index layer, conductive layer and top layer can all be formed by sputtering or similar processes which do not require high temperatures, so that plastic substrates can be used. The electrodes can be used, for example, in flat panel displays and in touch screen displays.

Process for forming electrodes

An antireflection coating comprises one or more inorganic antireflection layers (typically metal oxide or silica layers) and a polymer layer cured in situ, the polymer layer having a refractive index not greater than about 1.53 over the wavelength range of 400 to 700 nm and a thickness of from about 20 to about 200 nm. The polymer layer provides good scratch and fingerprint protection, and also enables the thicknesses of the inorganic antireflection layers to be reduced, thereby reducing the cost of the coating.

There is described a nanoporous receiver element for use in thermal mass transfer imaging applications. The receiver element comprises a substrate carrying an image-receiving layer comprising particulate material and a binder material. The substrate may comprise a material having a compressibility of at least 1% under a pressure of 1 Newton per mm (1 MPa). Optionally, there may be provided, between the substrate and the nanoporous receiving layer, a layer having a thickness of less than about 50 &mgr;m which is comprised entirely of a material having a compressibility of less than about 1% under a pressure of 1 MPa. Alternatively, the substrate may comprise only the material having a compressibility of less than about 1% under a pressure of 1 MPa, provided that the thickness of the substrate does not exceed about 50 &mgr;m. The image-receiving layer comprises particulate material and a binder material, has a void volume of from about 40% to about 70% and a pore diameter distribution wherein at least 50% of the pores having a diameter greater than about 30 nm have diameters less than about 300 nm and at least 95% of the pores having diameters greater than about 300 nm have diameters less than about 1000 nm.

Thermal mass transfer imaging system

A thermal transfer recording system wherein an area of a thermal transfer imaging medium is heated imagewise while in contact only with a thermal printing head and the imaged area of the thermal transfer recording medium subsequently transferred to a receiver material.

An antireflection coating includes one or more inorganic antireflection layers (typically metal oxide or silica layers) and a polymer layer cured in situ, the polymer layer having a refractive index not greater than about 1.53 over the wavelength range of 400 to 700 nm and a thickness of from about 20 to about 200 nm. The polymer layer provides good scratch and fingerprint protection, and also enables the thicknesses of the inorganic antireflection layers to be reduced, thereby reducing the cost of the coating.

An antireflection film comprises a transparent substrate carrying on one surface a polymeric antireflection layer, this antireflection layer having a refractive index at least about 0.02 lower than that of the substrate and being formed from a cured polymer comprising repeating units derived from a fluoroalkene, an alkyl acrylate or methacrylate and a polyfunctional acrylate monomer. No inorganic antireflection layer is present between the substrate and the polymeric antireflection layer.
