The present invention relates to a loaded particle comprising at least one fluorescent dye, and in particular, a fluorescent dye with a large Stokes shift. The invention further relates to a method for producing an loaded latex particle, loaded with a fluorescent dye having a large stokes shift. In addition, the present invention relates to latex particles loaded with fluorescent dyes that are organic solvent soluble and insoluble in water. In a preferred embodiment, when the dyes are loaded into the water soluble latex particle, an increase is observed in quantum yield of fluorescence as compared to the quantum yield of the dye in aqueous solvent.

Loaded latex optical molecular imaging probes containing lipophilic large stokes shift dyes

A color contrast image in imaged lithographic printing precursors can be obtained by contacting the imaged precursor with a coloration solution containing a colorless form of a photochromic compound. Residual amounts of this compound attached to the oleophilic surface of the imaged precursor can be changed to its colored form when exposed to UV light. The coloration solution can be an alkaline or acidic developer or an alkaline or acidic solution used separately after development. The coloration solution can also be a gum solution.

Developers and method of coloring lithographic printing members

A negative-working imageable element has an imageable layer that includes an infrared radiation absorbing dye that upon exposure to thermal irradiation, changes from colorless to a visible color or from one visible color to another visible color, providing a &#x394;E of at least 5 between the exposed and non-exposed regions of the imageable layer within 3 hours of its exposure to 300 mJ/cmat a laser power of 15 Watts. The imageable element can be imaged to provide images with improved contrast for print-out. The imageable layer includes a primary polymeric binder that has a backbone to which are attached pendant poly(alkylene oxide) side chains, cyano groups, or both, and is optionally present in the form of discrete particles.

On-press developable elements and methods of use

The present invention relates to a diagnostic contrast agent comprising a water dispersible, near-infrared tricarbocyanine, enamine-functionalized dye having a Stoke shift of greater than 50 and represented by five general formulae. The present invention also relates to a method for making a dye-conjugate utilizing the novel dye and a method of identifying a biological compound using the novel dye conjugate.

A method and apparatus for delivering a mixture of compressed fluid and marking material and depositing the marking material in a pattern onto a substrate, includes a high pressure source of a mixture of compressed fluid and marking material. A micro-machined manifold includes a plurality of micro-nozzles, a fluid chamber, and an entrance port with portions of a first surface of the micro-machined manifold defining the entrance port with the entrance port being connected in fluid communication with the fluid chamber. Each of the micro-nozzles having an inlet and an outlet with the inlet being connected in fluid communication with the fluid chamber and the outlet being located on the second surface of the micro-machined manifold. Each micro-nozzle is shaped to produce a directed beam of the mixture of compressed fluid and marking material beyond the outlet of the micro-nozzle. A housing is connected in fluid communication with the high pressure source and the entrance port of the micro-machined manifold with the connection being a sealed connection. Optionally, a device operable to capture marking material that does not adhere to the substrate can be included.
