Ink jet printing method

A composition that is useful in a wide variety of applications comprises a latex having water as a continuous phase and, as the dispersed phase, hydrophobic polymer particles having associated therewith both a dye and a stabilizer for the dye. In a particularly preferred embodiment, the dye is an infrared absorbing dye. The composition can be used as an inkjet ink, as a coating composition to form an infrared sensitive optical recording layer or for other purposes.

Loaded latex compositions with dye and stabilizer

This invention comprises a composition containing a hydrophilic colloid and a water soluble polymer of boric acid, and optionally a hardening agent for the hydrophilic colloid. The hydrophilic colloid is preferably gelatin. This invention also comprises a photographic element in which at least one layer thereof contains a hydrophilic colloid and a water-soluble polymer of boric acid and a method of making the photographic element.

Hydrophilic colloid composition

Color photographic materials comprise a support bearing a silver halide emulsion and at least one water-dispersible polymeric coupler. The polymeric coupler is formed by polymerization of a mixture of at least one ethylenically unsaturated coupler monomer containing a dye-forming coupler moiety and at least one ionic monomer containing an ionizable functional group, in a water-miscible organic solvent. The polymeric coupler contains less than 10 weight percent of the ionic monomer.

Methods of forming polymeric couplers

A photographic element with particular polymeric ultraviolet absorbers. The ultraviolet absorbers have repeating units of the formula: ##STR1## wherein: X is O or NH;

Photographic elements incorporating polymeric ultraviolet absorbers

Color photographic materials containing polymeric couplers

Color photographic elements contain polymeric dye-forming couplers in which the coupler moiety is joined to the polymer backbone via a linking group containing an ether moiety. Increased dye density yield is obtained.
