An inkjet receiving medium including a substrate and having a topmost layer coated thereon at solid content of from 0.1 to 25 g/m, wherein the topmost layer comprises from 30-70 wt % of one or more aqueous soluble salts of multivalent metal cations and at least 0.05 g/mof a cross-linked hydrophilic polymer binder. Improved optical density, reduced mottle and improved wet abrasion resistance are provided when the receiver is printed with an aqueous pigment-based ink. In further embodiments, the topmost layer may further comprise a latex dispersion for improved image durability.

Inkjet recording medium and methods therefor

A photographic element comprising a support, a layer containing an image dye ligand or dye ligand forming material and a layer containing a dye mordant, wherein the mordant layer has associated therewith:

Photographic elements containing polymers which coordinate with metal

A coating composition useful in forming conductive layers comprises a conductive, water-dispersible, particulate polymer and a crosslinkable latex binder. The crosslinkable latex has a first glass transition temperature before crosslinking of substantially less than 50.degree. C. and a second glass transition temperature after crosslinking and coalescing of substantially greater than 50.degree. C. wherein the first and second glass transition temperatures differ by more than 4.degree. C. The coating composition can be coated on a variety of supports to produce conductive elements. The coating compositions are particularly useful in forming photographic elements which are resistant to the buildup of static charge and ferrotyping.

Antistatic compositions comprising crosslinkable latex binders

Copolymers containing an acrylamidophenol as a crosslinking site and the corresponding crosslinked polymers are disclosed. The acrylamidophenol unit can be copolymerized with a wide variety of other monomers to provide crosslinkable and crosslinked polymers with useful properties. The acrylamidophenol unit provides for crosslinking at low pH with conventional crosslinking agents. The acrylamidophenol monomer unit is present in the copolymer from about 0.5 to 50 percent by weight and has the formula: ##STR1## wherein: x is 1 or 0,

Crosslinkable polymers containing acrylamidophenol units

A polymer comprising acrylamide units or anionic sulfonate units and a unit having the formula: ##STR1## wherein: R is H, halogen or alkyl;

Element for photographic use containing crosslinkable polymers having

A photographic element comprising a support, a layer containing certain photographically useful fragments and a layer containing a dye mordant composition comprising a polymer having recurring units of the formula: ##STR1## wherein: A comprises polymerized units of ethylenically unsaturated monomers;

Photographic film units containing aza heterocyclic polymeric mordants

A photographic element comprising a support, a layer containing certain photographically useful and/or active fragments and a layer containing a dye mordant composition comprising a polymer having recurring units of the formula selected from the group consisting of: ##STR1## wherein: R.sup.2 is hydrogen or alkyl;

Photographic film units containing a polymeric mordant which covalently

Polymers containing pendent substituted ethylsulfonyl, vinylsulfonyl or styrylsulfonyl groups are useful as gelatin hardeners or can be crosslinked by bis-nucleophiles or by exposure to ultraviolet light.

Crosslinkable polymers having vinylsulfonyl groups or styrylsulfonyl

Disclosed herein are microgel compositions useful for the preparation of electrically conductive or antistatic layers in radiation sensitive materials, and particularly in photographic materials. The compositions comprise an aqueous dispersion of a sulfonated crosslinked polymer, preferably mixed with a binder. The polymer particles average less than one micron in diameter. Also disclosed herein is a method of preparing these microgel compositions.

Photographic silver halide element with a layer of sulfonated polymer

Antistatic compositions comprising a highly crosslinked vinylbenzyl quaternary ammonium polymer and a hydrophobic binder are described. Elements, particularly photographic elements, having a layer of the antistatic compositions are also described. The compositions are characterized by a binder to antistatic polymer ratio of about 10:1 to 1:1. The compositions are highly conductive in thin layers and retain substantial conductivity at low relative humidity. Layers of the antistatic compositions are particularly useful for photographic elements because they can be contacted over a wide range of conditions with a hydrophilic layer without resulting in ferrotyping.
