TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Film: In the film, the sheet resistance of the conductive layer is at least 1 ohm per square; the average primary particle diameter of the electrically conductive particles is not greater than 100 nm; the poly(vinyl alcohol) has average molecular weight (Mw) of 10000-30000; the transparent conductive layer has a thickness not greater than 10 mu m; and the ratio of Wm:Wp is 3:1-4:1 (preferably 3.2:1-3.8:1). Preferred Composition: The composition (C1) comprises (wt.%) electrically conductive particles (10-30) and poly(vinyl alcohol) (1-10). Preferred Component: The electrically conductive particles are selected from indium tin oxide, antimony tin-oxide and aluminum zinc oxide (preferably indium tin oxide).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The solvent comprises water and further comprises at least one co-solvent selected from a water-soluble or water-miscible solvent (preferably alcohol, acetone, butan-2-one, pentan-2-one, pentan-3-one, tetrahydrofuran, N-methylformamide, N,N-dimethyl formamide, N,N-dimethylacetamide, N-methylpyrrolidone and/or dimethylsulfoxide, especially methanol, ethanol, propan-1-ol, propan-2-ol, butan-1-ol, 2-methoxyethan-1-ol, 2- ethoxyethan-1-ol, 1-methoxypropan-1-ol, 1-ethoxypropan-1-ol, ethane-1,2-diol, propane-1,3-diol and propane-1,2,3-triol, particularly methanol, ethanol, propan-2-ol, acetone and tetrahydrofuran).    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The polymeric substrate is a polyester substrate selected from poly(ethylene terephthalate) and poly(ethylene 2,6-naphthalate). EXAMPLE - To a 25 wt.% aqueous dispersion of indium tin oxide nanoparticles (1.4 g) was added 24 wt.% aqueous solution of poly(vinyl alcohol) (0.4 g). The coating preparation was vigorously agitated and then applied onto a 125 mu m heat-stabilized poly(ethylene terephthalate) film and was tested for transmission over the visible range (TLT), haze and sheet resistance per 1000 (ohm/square) which were 67%, 44% and 840 per 1000 (ohm/square) respectively.
