The present invention relates to an electronically conductive particle comprising an acicular substrate in contact with an electronically conductive polymer. Another embodiment comprises an article comprising electronically conductive particles comprising an acicular substrate in contact with an electronically conductive polymer. A further embodiment comprises a method for making electronically conductive particles comprising providing at least one acicular substrate, combining at least one monomer with said at least one acicular substrate, and mixing at least one catalyst with said at least one acicular substrate and said at least one monomer.

Conductive polymers on acicular substrates

The present invention is an imaging element which includes a support, an image-forming layer superposed on the support and an electrically-conductive layer superposed on the support. The electrically-conductive layer is composed of a sulfonated polyurethane film-forming binder and an electrically-conductive polymer.

Antistatic layer with electrically conducting polymer for imaging element

The present invention is an imaging element which includes a support, an image-forming layer superposed on the support, and an electrically-conductive layer superposed on the support. The electrically-conductive layer includes a layered siliceous material, an electrically conducting polymer that can intercalate inside or exfoliate said layered siliceous material and a film-forming binder.

Antistatic layer for imaging element

An imaging element such as a photographic, electrostatic, or thermal imaging element is comprised of a support, an image-forming layer, and a transparent electrically conductive layer which includes an effective amount of poly(3,4-ethylene dioxypyrrole/styrene sulfonate). In a preferred embodiment, the poly(3,4-ethylene dioxypyrrole/styrene sulfonate) is dispersed in a polymeric binder.

Imaging element containing poly(3,4-ethylene dioxypyrrole/styrene

A recording element having at least one layer comprising a crosslinked polymer having polymeric backbone moieties and crosslinking moieties, the polymeric backbone moieties containing tertiary nitrogen atoms, the crosslinking moieties connecting polymeric backbone moieties at the teritary nitrogen atoms by conversion of the tertiary nitrogen atoms to quaternary amine, the crosslinking moiety having the structure ##STR1## where R' is independently alkyl or aryl and m is an integer of from 1 to 10.

Recording element having a crosslinked polymeric layer

Photocrosslinkable, organic-solvent-soluble polymers having a Tg greater than 200.degree. C., are disclosed. The polymer contains sufficient radiation-sensitive crosslinkable units to render the polymer insoluble in organic solvents on exposure to radiation to which the crosslinkable units of the polymer are sensitive.

Photocross-linkable, organic solvent-soluble polymers having a Tg greater than 200.degree. C. are disclosed. The polymers contain sufficient radiation-sensitive cross-linkable units to render the polymers insoluble in organic solvents on exposure to radiation to which the cross-linkable units are sensitive. Also disclosed are supports, particularly supports having a radiation-sensitive surface, having thereon a layer of the described photo-corss-linkable polymers. The polymers are capable of receiving heat-transferrable dyes and are useful in forming color filter arrays for solid-state imaging devices. A particularly convenient method of forming solid-state color imaging devices having a layer containing an array of color filters is also disclosed.
