Abstract:
The polymerization and copolymerization of photographically useful vinyl monomers can be effected by dissolving such monomers in an isotropic oil-in-water microemulsion or in an isotropic water-in-oil microemulsion, each comprising monomers or comonomers, surfactants and/or cosurfactants, water, and optionally electrolytes. The microemulsion may be characterized as transparent or nearly transparent to the eye at 1% (w/w) or greater monomer, ultrafine in particle (droplet) size (typically in the range of 30 to 900 .ANG. in diameter), and spontaneously formed upon combining all the components with moderate stirring. The polymerization process is subsequently initiated with free radical initiators or with ultraviolet light. The components are chosen so that photographically useful polymers or photographically useful latexes are obtained, and said polymers or latexes may be coated in a photographic element.
Abstract:
The present invention is generally directed to treated silica particulates for use in ink-jet media coatings, comprising silica particulates being surface-activated by a surface activating agent; the surface active agent including an aluminum chloride hydrate, and where the silica particulates are also reagent-modified by an organosilane reagent; the organosilane reagent including an amine-containing silane.
Abstract:
The present invention is drawn to a method of treating silica in an aqueous environment. The method can comprise steps of dispersing silica particulates in an aqueous environment to form an aqueous dispersion; reversing the net charge of a surface of the silica particulates from negative to positive using a surface activating agent, thereby forming surface-activated silica particulates dispersed in the water; and contacting the surface-activated silica particulates with organosilane reagents to form reagent-modified and surface-activated silica particulates.
Abstract:
A polymer for an ink receiving layer of an inkjet recording element includes at least one first monomer chemically bonded to at least one second monomer. The second monomer includes a silane functional group. The at least one second monomer is distributed along a carbon backbone of the polymer at a non-terminal end. The polymer is capable of chemically bonding with an inorganic particulate substance.
Abstract:
A system for forming a microporous ink receptive coating includes a fusible latex configured to coat a substrate, wherein the fusible latex includes a hard core material and a soft shell material, wherein the latex exhibits self-adhesive properties at a system operation temperature.
Abstract:
The present invention is drawn to a media sheet for ink-jet printing and can comprise a media substrate and a coating composition applied to the media substrate to form an ink-receiving layer. The ink-receiving layer can include semi-metal oxide or metal oxide particulates, at least 5 wt % of a water soluble coating formulation additive, and a binder. The media sheet can also have a wash conductivity less than about 80 microsiemens/cm, said wash conductivity determined by measuring the conductivity of a 50 mL bath of deionized water after placing a 100 cm2 sample of the media sheet in the deionized water for 45 seconds at room temperature under agitation.
