<p>The invention relates to novel pigment-free colored liquids, i.e. especially inks or China inks, for fiber-tip, felt-tip, and ball-point pens and to the use thereof in ink jet methods as well as in fountain pens. The colored liquids contain, as constituents: (I) 17.3 to 23.8, especially 19.8 vol.-%, base inks or a China ink solution; (II) 39.7 to 52.9, especially 46.3 vol.-%, of an aqueous dispersion of thermoplastic and selfcrosslinking acrylic polymers serving as binding agents, and UV filters, especially, Plextol® (III) 4.7 to 5.8, especially 5.3 vol.-%, ethanol; (IV) 20.6 to 21.7, especially 21.2 vol.-%, water; (V) 2.6 to 6.6, especially 3.9 vol.-%, of a basic auxiliary agent; (VI) 2.6 to 6.6, especially 3.3 vol.-%, thickening agents, especially maple syrup. The invention also relates to pigmented colored liquids, i.e. inks or China inks for fiber-tip and felt-tip pens for ink jet methods. The colored liquids contain the following constituents: (VII) 19.3 to 27.1, especially 23.2 vol.-%, of a base pigment or China ink solution; (II) 41.8 to 51.1, especially 46.5 vol.-%, of an aqueous dispersion of thermoplastic and selfcrosslinking acrylic polymers serving as binding agents and UV filters, especially, Plextol®; (III) 3.4 to 4.2, especially 3.8 vol.-%, ethanol; (IV) 15.1 to 15.8, especially 15.5 vol.-%, water; (VIII) 7.7 to 10.8, especially 9.3 vol.-%, of a colorant concentrate solution; (IX) 1.4 to 1.7, especially 1.5 vol.-%, of defoaming agents.</p> |
