Conducting composite polymer beads and methods for preparation and use thereof

Composite conducting polymer particles are described, wherein surface-treated supporting polymer particles having a charged surface of a first polarity are provided with a coating of conducting polymer of opposite polarity applied to the surface thereof. Suitably, the supporting insulating polymer particles are subjected to a surface treatment which introduces charged moieties thereon. The conducting polymer may be doped with at least one dopant to improve its conductivity. The novel particles have desirable rheological properties, and particularly when admixed with at least one processible polymer may be used to prepare products comprising conductive polymers in a particularly facile manner.

Image-receiving element for diffusion transfer photographic and photothermographic film products

An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type wherein the image-receiving element is designed to be removed or 'peeled-apart' from a photosensitive element following exposure and processing. The present image-receiving element comprises in sequence, a support, an image-receiving layer, and a strip-coat layer. The strip-coat layer serves to facilitate separation of the image-receiving layer from a photosensitive element after processing. The strip-coat layer comprises a copolymer including: 1) at least about 50 % by weight of monomer units, the same or different, derived from an ethylenically unsaturated carboxylic acid or salt thereof, 2) at least about 15 % by weight of monomer units of vinyl pyrrolidone, and 3) at least about 5 % by weight of monomer units, the same or different, represented by formula (I), wherein R1 of each monomer unit is independently selected from: hydrogen, a substituted or unsubstituted alkyl having 1 to 4 carbon atoms, cyano, and halogen; X of each monomer unit is independently selected from -NH- or -O-; and R2 of each monomer unit is independently selected from a hydroxy substituted alkyl group.
