Rachel Bogale Inventions, Patents and Patents Application Summary: The invention refers to an waterborne gel color pigmented gel color pigmented gel color pigmented gel ribbon printer inks for use in color printer which comprises an waterborne support, a gel color pigments, a polymer dispersing agent, a surface active agent and a co-solvent blend which comprises a C2-C8 endalkanediol or a blend thereof, a polyol/polyalkylene alkoxide concentrate, a periodic amide and its derivatives, and a trivalentalcohols.

It is characterized by outstanding ruggedness, good maintainability and high heating dependability in continuous and semi-permanent printing heads. It also reduces corrugation after printing without compromising printing performance.

Summary: The invention refers to an water-based magagenta etch bar code inkset for use in ink-jet printing, which comprises a blend of a self-dispersed magagenta pigmented surfacing which has been functionalized with a group and a xanthenic dyestuff. In addition, the inks of the present invention contain an water-based support, a polymer additives, a tenside and a co-solvent blend specifically chosen from the group of a C2-C8 terminus alkane diol, a cyclic sulfide compounds and their derivatives, a trivalent Alcohols and blends thereof.

In addition, the inks of the present invention contain an water-based support, a polymer additives, a tenside and a co-solvent blend specifically chosen from the group comprising a C2-C8-terminal alkane diol, a cyclic sulfide compounds and their derivatives, a trivalent Alcohols and blends thereof. It is preferable that the coating of the magnetic pigments is surface-modified with a group of bisphosphonates or sulfonates, especially bisphosphonates.

Mast-coloured inks offer outstanding durability, good chrome and service properties and high heating dependability in durable and semi-permanent print heads. Summary: The invention refers to an waterborne cyano etch ink formulation for use in etch printer inks, which comprises an waterborne support, a self-dispersing cyano pigments, a polymer additives, a surface active agent and a co-solvent blend which comprises a C2-C8-terminal alkane diol, a periodic alkane solvent and its derivatives, a polyol/polyalkylene oxidic conc. and a trivalent alkoxide.

The self-dispersion edyan pigments are preferentially surface-modified with a group of bisphosphonates. Cyano inks offer outstanding durability, outstanding colour rendition, good print head serviceability and high heating performance in durable and semi-permanent prints. Abstract: This invention provides for a pigmented dye formula containing a thin layer of warmth.

It consists of a special mixture of surfactants and waxes. Specifically, the growth consists of a straight line Polyethylenwachs and the Tensid is an Alkylethercarboxylat.
