Abstract: In a method for microfluidic printing of colored images on a receiver, including providing a first set of reservoirs containing colorant precursors for different colors; providing at least one reservoir containing a reactant; and reacting the colorant precursors and reactant(s) to provide colored pixels of the desired colors.

Abstract: An inkjet printing apparatus for printing continuous tone images on a receiver in response to a digital image, including a structure defining a plurality of colorant or colorant precursor receiving chambers, and another structure defining at least one mixing chamber for receiving a plurality of microdrops of colorants or colorant precursors from the colorant or colorant precursor receiving chambers to produce a desired colorant. The apparatus further includes a microdrop nozzle for each receiving chamber and in communication with the mixing chamber and a printing nozzle for each mixing chamber for causing a mixed drop to be delivered to the receiver.

Abstract: A thermal recording element consisting of a support having thereon a recording layer comprising hollow spherical beads dispersed in a hydrophilic binder, the beads having a mean diameter of about 0.2 .mu.m to about 1.5 .mu.m and a void volume of about 40% to about 90%.

Abstract: Novel azo dye-providing compounds and photographic elements containing such compounds are described. The present compounds contain a carrier moiety which, as a function of oxidation under alkaline conditions, provides a substance having a mobility different than that of the starting compound.

Abstract: Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 2-(5-nitro-2-pyridylazo)-1-naphthol dye moiety. The compound contains a ballasted carrier moiety which is capable of releasing the diffusible azo dye under alkaline conditions. The dye is transferred imagewise to an image-receiving layer where it is contacted with metal ions to form a metal-complexed azo dye transfer image of excellent stability.

Abstract: Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a novel releasable azo dye. The dyes are azophenols, or precursors of azophenols, and have electron withdrawing groups in each of the positions ortho to the phenolic hydroxy group.
