Abstract: Surface treated silica containing particles are combined with a resin to form a liquid prepolymer composition for use in additive manufacturing. A surface treatment on the silica containing particles may participate in polymerization of the composition. The silica containing particles may be colloidal silica or a silica polymer composite particle.

Abstract: Disclosed herein are aqueous ink compositions, e.g., inkjet ink compositions, comprising at least one colorant; and a nanocrystalline cellulose present in an amount ranging from 0.5% to 5% by weight, relative to the total weight of the composition. Also disclosed are aqueous dispersions for ink compositions, and methods of commercial inkjet printing.

Abstract: Compositions, systems, and methods of printing an ink-jet image are provided. The composition can be an ink-jet ink, comprising a liquid vehicle; from 0.5 wt % to 10 wt % of a polymer-dispersed pigment; and from 0.5 wt % to 10 wt % of a self-dispersed pigment selected from the group consisting of a second polymer-dispersed pigment and a small molecule-dispersed pigment.

Abstract: An ink composition is disclosed including a liquid vehicle and an ionically charged organic pigment and a hydroxylated hydrocarbon humectant having at least two hydroxyl groups. The ionically charged pigment may be black, blue, brown, cyan, green, violet, magenta, red, orange, yellow, mixtures thereof, and the like. The ionically charged pigment, due to the nature of its surface charge, is readily-dispersed in the liquid vehicle of the ink composition without the addition of a surfactant or other dispersing aid or additive. In a preferred embodiment, the ionically charged pigment has sufficient ionizable groups to maintain the colloidal stability of the pigment in the ink composition.Further disclosed is a method for generating printed images which include incorporating into a printing apparatus the ink compositions described above and generating an image onto a substrate.

Abstract: An ink composition is disclosed including a colorant and at least one polymer selected from the group consisting of polyvinylimidazole, derivatives of polyvinylimidazole, copolymers of vinylimidazole and copolymers of vinylimidazole derivatives. The present invention also relates to ink compositions including a colorant and at least one polymer selected from polyvinylpyridine, derivatives of polyvinylpyridine, copolymers of vinylpyridine and copolymers of vinylpyridine derivatives. Also disclosed is an ink composition comprising a pigment and at least one polymer selected from the group consisting of polyethyleneimine and derivatives thereof. Further disclosed is a method for generating printed images which include incorporating into a printing apparatus the ink compositions described above and generating an image onto a substrate.
