摘要:
A process of making a liquid ink comprising the steps of: (a) dissolving a polymer comprising units derived from at least a nitrogen-containing polymerizable monomer in a solvent with a Kauri-Butanol number greater than 30 to form a polymer solution; (b) dispersing colorant pigment particles in said polymer solution to form a colorant pigment dispersion; (c) removing at least some of said solvent from said colorant pigment dispersion to form treated colorant pigment particles; and (d) dispersing said treated colorant pigment particles in an organosol containing a carrier liquid having a Kauri-Butanol number less than 30.
摘要:
A base film including a substrate, an adhesion layer, a conductive layer, and a magnetic layer is provided. The adhesion layer preferably includes a sulfonated polyester/vinyl addition polymer, wherein the adhesion layer is disposed between the substrate and the conductive layer and improves adhesion between these layers, even under wet conditions. An adhesion layer is particularly useful in photographic elements and is at least located on a surface of the substrate that is opposite a silver halide emulsion layer, although emulsion receptivity can be enhanced by including an adhesion layer on the emulsion-side of the substrate.
摘要:
A photographic element comprising a polymeric film base, a silver halide emulsion layer, and an antistatic layer comprising a colloidal vanadium oxide and a vinyl addition polymer dispersion in a dry weight ratio of from 1:30 to 1:500. The antistatic layer may be present as a backing layer on the side of the base opposite the silver halide emulsion layer, as a subbing layer between the base and the emulsion layer in a single or double side coated photographic element, and/or as a subbing layer between the base and a different backing layer. No barrier layer is used over the antistatic layer.
摘要:
A vanadium oxide coating useful as an antistatic protection layer on a donor sheet or a receptor sheet of a thermal transfer system is provided. The preferred antistatic coating is formed from a composition of a vanadium oxide colloidal dispersion.
摘要:
A liquid ink for developing electrophotography images comprises: a) a carrier liquid having a Kauri-Butanol number less than 30; b) a grafted co-polymer comprising a (co)polymeric steric stabilizer covalently bonded to a thermoplastic (co)polymeric core that is insoluble in the carrier liquid, wherein the grafted co-polymer is derived from at least a polymerizable organic compound having at least one acid group or at least one acid group; c) a dispersant having, respectively, at least an amine group or at least one acid group to form an acid-base copolymer-dispersant system or a base-acid copolymer-dispersant system, wherein the mole ratio of the amine group to the acid group is between 0.3 and 1.5 in the base-acid copolymer-dispersant system and the mole ratio of the acid group to the base group in the acid-base copolymer dispersant system is between 0.3 and 1.5; and d) a positive charge director with the acid-base copolymer charge dispersant system and a negative charge director with the base-acid copolymer charge-dispersant system.

摘要:
A process for the preparation of a vanadium oxide colloidal dispersion is provided. The process includes a step of hydrolyzing vanadium oxoalkoxide with an excess of water to form a vanadium oxide colloidal dispersion containing at least a minimum effective amount of vanadium and no greater than about 3.5 wt-% vanadium, preferably containing about 0.3 wt-% to about 2 wt-% vanadium. The process can be carried out in the presence of an organic polymer or prepolymer to form a polymeric vanadium oxide colloidal dispersion.
摘要:
A delaminating coating for use in a thermal transfer system is provided that possesses both delaminating properties and antistatic properties. This delaminating coating can be used on a donor sheet or an intermediate carrying sheet of a thermal retransfer system. The preferred delaminating/antistatic coating is formed from a composition of a vanadium oxide colloidal dispersion.
摘要:
A flexographic printing plate comprising in the following order: a flexible substrate, a photohardenable composition, and a colloidal vanadium oxide antistatic layer. The antistatic layer provides protection from static induced defects until and after the flexographic plate is processed.
