Abstract: Organometallic salts useful for inkjet receptor media are disclosed. The organometallic salt can be a multivalent metal derivative of an aromatic carboxylic, sulfocarboxylic, sulfophenolic, or combination thereof. The aromatic moiety can be a simple aromatic, a condensed aromatic, a heterocyclic aromatic or a combination thereof. The multivalent metal ion can be derived from the group IIA to VIA and Group IB to VIIIB of elements in the Periodic Table. The organometallic salt simultaneously releases the multivalent metal cation and the organic acid anion for both pigment management and ink-drying.

Abstract: An imageable media is disclosed. An imageable media in accordance with the present invention comprises a substrate having a first surface and a porous layer overlaying the first surface of the substrate. In a preferred embodiment, for pigmented inks, a plurality of ink retaining silica particles are disposed within the porous layer. After inkjet imaging with pigmented ink, the porous layer may be fused to create a durable, tamper and scuff resistant, waterproof graphic without a laminate. In another preferred embodiment for dye based inks, a plurality of zeolite particles and a plurality of cross-linked polyvinylpyrrolidone particles are disposed within the porous layer. The porous layer may be imbibed with an ink retention coating for dye based inks. Imageable media made with this invention has utility for commercial graphics, labels and ID cards.

Abstract: Inkjet receptor media are disclosed that have both a fluid management system and a pigment management system for use with pigmented inkjet inks that produce vibrant, durable images. The fluid management system is provided by microporous media with the presence of surfactants, if needed. The pigment management system is provided by either fluorinated silica particles or multivalent metal salts impregnated into pores of the microporous media. Methods of making and using are also disclosed.

Abstract: A homopolymer or copolymer useful for inhibiting the migration of pigmented inks in porous inkjet receptor media is disclosed. The copolymer is comprised of at least two different hydrophilic monomers, each of whose homopolymers are hydrophilic yet the resulting copolymer from the different hydrophilic monomers is sparingly soluble in water. Methods of making and using such copolymer are also disclosed.

Abstract: A polymer useful for a multi-stage inhibiting of the migration of pigmented inks in porous inkjet receptor media is disclosed. The polymer is quite soluble in water and has quaternary amine functional groups. Methods of making and using such polymer are also disclosed.

Abstract: A drying agent for inkjet receptor media is disclosed. The drying agent can be an aromatic or aliphatic acid having sulfonic, carboxylic, phenolic or mixed functionalities thereof, which in combination with a multivalent salt is capable of drying the film in a manner to obtain a smudge-free rapidly dried image onto and in the medium when the image is printed. Methods of using the drying agent in a coating solution, on and in an inkjet receptor media, and in interaction with inkjet inks are also disclosed.

Abstract: Environmental stabilizing agents are stored in an adhesive adjoining, directly or indirectly, a film or membrane that requires protection from the environment. Such stabilizing agents include ultra-violet protectors and anti-oxidants. Migration of such environmental stabilizing agents from an adhesive to a film or membrane permits the use of new and different materials for such films and membranes because their method of manufacture no longer needs to accommodate the heat and processing sensitivities of the stabilizing agents.
