Abstract
Inkjet primer compositions are provided, including those comprising water, a co-medium, one or more types of nanocellulose, and resin particles, wherein the resin particles comprise a polymerization product of reactants comprising one or more types of monomers. Inkjet sets for inkjet printing systems are also provided, including those comprising such an inkjet primer composition; and an aqueous inkjet ink composition for printing on an ink-receiving layer, the ink-receiving layer comprising the resin particles of the inkjet primer composition, the aqueous inkjet ink composition comprising water, a colorant, and additional resin particles.
Claims19
An inkjet primer composition comprising water, a co-medium, one or more types of nanocellulose, and resin particles, wherein the resin particles comprise a polymerization product of reactants comprising one or more types of metal chelating monomers, wherein the one or more types of metal chelating monomers comprise one or more types of phosphoric acid monomers;
- one or more types of sulfonic acid monomers;
- or both one or more types of phosphoric acid and one or more types of sulfonic acid monomers,
- wherein the reactants further comprise one or more types of acidic monomers comprising (meth)acrylic acid monomers,
- wherein a total amount of polymerized metal chelating monomers and polymerized (meth)acrylic acid monomers in the resin particles is at least about 8 weight % and a total amount of polymerized metal chelating monomers in the resin particles is at least about 4 weight %,
- wherein a weight ratio of a total amount of polymerized metal chelating monomers in the resin particles to a total amount of polymerized (meth)acrylic acid monomers in the resin particles is less than about 0.5, and
- further wherein the inkjet primer composition is free of a colorant.
An inkjet set for an inkjet printing system, the inkjet set comprising:
- an inkjet primer composition comprising water, a co-medium, one or more types of nanocellulose, and resin particles, wherein the resin particles comprise a polymerization product of reactants comprising one or more types of metal chelating monomers;
- and
- and an aqueous inkjet ink composition for printing on an ink-receiving layer, the ink-receiving layer comprising the resin particles of the inkjet primer composition, the aqueous inkjet ink composition comprising water, a colorant, and additional resin particles,
- wherein in the inkjet primer composition, the one or more types of metal chelating monomers comprise one or more types of phosphoric acid monomers;
- one or more types of sulfonic acid monomers;
- or both one or more types of phosphoric acid monomers and one or more types of sulfonic acid monomers,
- wherein the reactants further comprise one or more types of acidic monomers comprising (meth)acrylic acid monomers,
- wherein a total amount of polymerized metal chelating monomers and polymerized (meth)acrylic acid monomers in the resin particles is at least about 8 weight % and a total amount of polymerized metal chelating monomers in the resin particles is at least about 4 weight %,
- wherein a weight ratio of a total amount of polymerized metal chelating monomers in the resin particles to a total amount of polymerized (meth)acrylic acid monomers in the resin particles is less than about 0.5, and
- further wherein the inkjet primer composition is free of a colorant.
