Abstract
An inkjet receptive composition for use on glossy paper substrates may include a polymer binder, a multivalent salt, a pigment, a surfactant, a defoamer, and water. The polymer may be a polyurethane dispersion. The multivalent salt may be calcium chloride, and the water may be present in an amount greater than about 40 wt %. The inkjet receptive composition may have a viscosity in the range of about 3 and about 500 cP.
Claims20
An inkjet receptive composition for use on glossy paper substrates comprising:
- a polymer binder, the polymer comprising a polyurethane dispersion;
- a multivalent salt, the multivalent salt comprising calcium chloride;
- a pigment;
- a surfactant;
- a defoamer;
- and
- water present in an amount greater than about 40 wt %, wherein the inkjet receptive composition can be applied to the substrate using a flexographic printing system.
A an inkjet receptive composition for use on matte substrates comprising:
- a first polymer binder, wherein the first polymer binder is a polyurethane dispersion;
- a second polymer binder;
- a multivalent salt;
- a first pigment, the first pigment comprising colloidal silica;
- a second pigment, the second pigment comprising calcium carbonate;
- surfactant;
- a defoamer;
- and
- water present in an amount between about 20 and about 40 wt %, wherein the inkjet receptive composition can be applied to the substrate using a flexographic printing system.
A method of printing comprising:
- applying an inkjet receptive composition to a substrate, the inkjet receptive composition comprising a polymer binder, a multivalent salt, a pigment, a surfactant, a solvent, and water, wherein the inkjet receptive composition is applied in an amount between about 0.2 and about 1.5 g/m2, and the pigment is one of colloidal silica and calcium carbonate;
- heating the inkjet receptive composition;
- and
- jetting an ink onto the inkjet receptive composition.
