The present disclosure is directed to transparent composites having anti-fogging properties and anti-fog coating compositions for providing anti-fogging properties. The anti-fogging layers can contain an adhesive polymer, a hard polymer, and a hydrophilic polymer, wherein the adhesive polymer, hard polymer, and hydrophilic polymers are different. In further embodiments, composites are described including a substrate layer; a first adhesive layer; a first transparent layer; a second adhesive layer; a second transparent layer; and an anti-fog layer.

A method of patterning a conductive polymer includes providing a conductive polymer layer coated over a first support followed by pattern-wise transferring a layer containing polyvinyl acetal from a second support onto the conductive polymer to form a mask with at least one opening. The masked conductive polymer is subjected to treatment through the opening that changes the conductivity of the conductive polymer by at least one order of magnitude in areas not covered by the mask.

A laminate donor element can be used to transfer a composite of a metal grid and an electronically conductive polymer to a receiver sheet for use in various devices. The laminate donor element has a donor substrate, a metal grid that is disposed over only portions of the donor substrate, leaving portions of the substrate uncovered by the metal grid, and an electronically conductive polymer that covers the portions of the donor substrate that are uncovered by the metal grid. The composite of metal grid and electronically conductive polymer exhibits a peel force of less than or equal to 40 g/cm for separation from the donor substrate at room temperature. The resulting article has a substrate on which a reverse composite of the metal grid and electronically conductive polymer is disposed, which article can be incorporated into various devices.

A method of assembling an electronic device includes providing a transparent conductive polymer layer coated over a first support followed by pattern-wise forming a transparent mask with at least one opening over the conductive polymer. The masked conductive polymer is subjected to treatment through the opening that changes conductivity of the conductive polymer by at least one order of magnitude in areas not covered by the mask to form a first electronic component. The first electronic component having the mask is secured to a second electronic component, thereby forming the electronic device.

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.

Image receiver elements with aqueous dye receiving layer

A thermal transfer donor element can be used to provide a clear protective overcoat on a thermal image receiver element from a thermal transferable protective clear film on the donor element. This thermal transferable protective clear film includes a transparent poly(vinyl acetal) binder to which are attached silicone groups to improve scratch resistance of the transferred protective overcoat. Such protective overcoats can also be applied over thermally transferred dye images.

Thermal transfer donor element

An image receiving element has an extruded compliant layer, an extruded image receiving layer, and a topcoat immediately adjacent the extruded image receiving layer. The extruded image receiving layer is non-crosslinked and has a glass transition temperature (T) of from about 40&#xb0; C. to about 80&#xb0; C. whereas the topcoat is an aqueous-coated layer and has a Tthat is within a range of plus or minus 10&#xb0; C. of the Tof the extruded image receiving layer. The dry thickness ratio of the topcoat to the extruded image receiving layer is from 1:2 to 1:20.

Image receiver elements with overcoat

An image receiver element includes a water-soluble or water-dispersible polyurethane binder in the image receiving layer. This polyurethane has a Tof from about 60 to about 80&#xb0; C., a molecular weight of at least 25,000, and an acid number of from about 16 to about 35 mg KOH/g. Moreover, the polyurethane comprises from about 42 to about 60 weight % of recurring urethane units, from about 8 to about 20 weight % of alkylene glycol recurring units, from about 18 to about 40 weight % of carbonate recurring units having aliphatic side chains, and from about 3 to about 15 weight % of recurring units having a water-soluble or water-dispersible acid group, based on total binder weight.

Image 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.

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.
