Abstract
An aqueous pigmented ink for use in a capillary reservoir system comprises at least one pigment, at least one water-dispersible, film-forming component, about 0.5 to about 4.5 wt % of at least one suspension substance and about 0.01 to about 0.5 wt % of a gel former combination in an aqueous vehicle, the gel former combination comprising at least one mineral gel former and at least one organic thickener.
Claims17
An aqueous pigmented ink, the aqueous pigmented ink comprising:
- at least one pigment,
- at least one water-dispersible film-forming component,
- at least one suspension substance in an amount of 0.5-4.5 wt % of the aqueous pigmented ink, wherein the at least one suspension substance is fumed silica, and
- a gel former combination in an aqueous vehicle, wherein the gel former combination is present in an amount of 0.01-0.5 wt % of the aqueous pigmented ink and the gel former combination comprises hectorite, xanthan gum, and cellulose in a weight ratio of 1:1:1,
- wherein the at least one pigment is suspended in the at least one suspension substance and the gel former combination.
A pen comprising a capillary reservoir system and an aqueous pigmented ink, the aqueous pigmented ink comprising:
- at least one pigment,
- at least one water-dispersible film-forming component,
- at least one suspension substance in an amount of 0.5-4.5 wt % of the aqueous pigmented ink, wherein the at least one suspension substance is fumed silica, and
- a gel former combination in an aqueous vehicle, wherein the gel former combination is present in an amount of 0.01-0.5 wt % of the aqueous pigmented ink and the gel former combination comprises hectorite, xanthan gum, and cellulose in a weight ratio of 1:1:1,
- wherein the at least one pigment is suspended in the at least one suspension substance and the gel former combination.
A refill container for a pen, the refill container comprising a reservoir and an aqueous pigmented ink, the aqueous pigmented ink comprising:
- at least one pigment,
- at least one water-dispersible film-forming component,
- at least one suspension substance in an amount of 0.5-4.5 wt % of the aqueous pigmented ink, wherein the at least one suspension substance is fumed silica, and
- a gel former combination in an aqueous vehicle, wherein the gel former combination is present in an amount of 0.01-0.5 wt % of the aqueous pigmented ink and the gel former combination comprises hectorite, xanthan gum, and cellulose in a weight ratio of 1:1:1,
- wherein the at least one pigment is suspended in the at least one suspension substance and the gel former combination.
