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.
Claims7
An inkjet receptive composition for use on glossy paper substrates comprising:
- a non-anionic polymer binder, the polymer binder comprising a polyurethane dispersion present in an amount from about 5 to about 15 wt %;
- a multivalent salt, the multivalent salt comprising calcium chloride;
- a pigment, the pigment comprising colloidal silica;
- a surfactant;
- a defoamer;
- and
- water present in an amount greater than about 40 wt %, wherein the inkjet receptive composition has a viscosity of between about 3 and about 500 cP, and wherein a ratio of pigment wt % to polymer binder wt % is within a range from about 2:1 to about 4:1.
