This invention relates to a silver halide photographic material comprising at least one silver halide emulsion comprising silver halide grains having associated therewith:

Silver halide material comprising low stain antenna dyes

Substrate for protein microarray containing functionalized polymer

A gelatin-based substrate for fabricating protein arrays, the substrate containing: gelatin and a trifunctional compound A&mdash;L&mdash;B; wherein A is a functional group capable of interacting with the gelatin; L is a linking group capable of interacting with A and with B; and B is a functional group capable of interacting with a protein capture agent. A may be the same or different from B.

Method for making biochip substrate

Photographic material having improved color reproduction

A nozzle plate for an ink jet printhead, the nozzle plate having the following layers in the order recited: a) a first monomolecular layer of an organic material having first and second functional groups, the first functional group of the first monomolecular layer being bound to the surface of the nozzle plate, and the second functional group of the first monomolecular layer being bound to a second monomolecular layer, and b) the second monomolecular layer of an organic material having first and second functional groups, the first functional group of the second monomolecular layer being bound to the second functional group of the first monomolecular layer, and the second functional group of the second monomolecular layer is an anti-wetting group.

Replenishable coating for printhead nozzle plate

Continuous ink jet printing process

Photographic material having enhanced light absorption

A method for treating a metallic oxide or metallic nitride ink jet printhead nozzle plate comprising stamping the front surface thereof with an anti-wetting agent using an elastomeric stamp.

Coating of printhead nozzle plate

Color photographic material having enhanced light absorption

An ink jet nozzle plate is provided comprising an outer surface having a self-assembled monolayer thereon comprising a mixture of at least one hydrophobic compound and at least one ionic compound, which monolayer renders the outer surface non-wetting with respect to aqueous ink solutions. In accordance with preferred embodiments, the self-assembled monolayers comprises a mixture of hydrophobic alkyl thiols and charged alkyl thiols. An advantage of coatings in accordance with the invention is that they provide improved non-wetting characteristics after contact with ink.

Nozzle plate with mixed self-assembled monolayer

Photographic material having enhanced light absorption and low dye stain

A method for replenishing fouled coatings on a nozzle plate for an ink jet printhead, the nozzle plate comprising the following layers in the order recited: i) a first monomolecular layer of an organic material having first and second functional groups, the first functional group of the first monomolecular layer being bound to the surface of the nozzle plate, and the second functional group of the first monomolecular layer being bound to a second monomolecular layer, and ii) the second monomolecular layer of an organic material having first and second functional groups, the first functional group of the second monomolecular layer being bound to the second functional group of the first monomolecular layer, and the second functional group of the second monomolecular layer being an anti-wetting group, the second monomolecular layer having been fouled; the method comprising A) unbinding the first functional group of the fouled second monomolecular layer so that it is no longer bound to the second functional group of the first monomolecular layer; B) removing the fouled second monomolecular layer; and C) reattaching a new, unfouled second monomolecular layer to the first monomolecular layer; the new, unfouled second monomolecular layer comprising an organic material having first and second functional groups, the first functional group of the second new, unfouled monomolecular layer being bound to the second functional group of the first monomolecular layer, and the second functional group of the new, unfouled second monomolecular layer being an anti-wetting group.

Method for replenishing coatings on printhead nozzle plate

A method for cleaning an ink jet print head nozzle plate having an anti-wetting layer formed thereon, wherein an aqueous solution of a metal salt of a taurine surfactant is applied to the nozzle plate and then removed.

Method for cleaning an ink jet print head

A silver halide color photographic material comprises at least one silver halide emulsion comprising silver halide grains having associated therewith at least two dye layers comprising
