Abstract

The present invention relates to writing color liquid based on 0.01 to 50.00 parts by weight dyes, from 5.00 to 70.00 parts by weight against premature drying, the rest to 100.00 parts are distilled and / or deionized water and writing fluid contains further, means that make it easy to use removal from contaminated fabrics, by hand etc.

Description

The present invention provides a writing ink fluid for writing instruments known as markers or markers.

Previously known writing fluids consist of a solution of dyes in a solvent consisting of a mixture of distilled or deionized water with means which prevent the writing fluids from drying out in the markers and markers. Polyhydric alcohols are most commonly used, of which ethylene glycol, diethylene glycol, triethylene glycol, propylene glycols, glycerin, or mixtures thereof are most commonly used. Writing fluids also contain active ingredients which are used to reduce their surface tension and thus improve their function in writing instruments. .

As far as dyes are concerned, mainly synthetic dyes are used, most often azo dyes, diarylmethane and triarylmethane dyes, in some cases phthalocyanine, quinoneimine, aminoanthraquinone or azomethine dyes are also used.

The disadvantage of the known writing fluids is the fact that their use often contaminates clothes, hands, furniture textiles, etc. Colored stains are very difficult to remove from these objects, or they can not be removed at all.

Said disadvantages are eliminated by the writing fluid according to the invention.

The essence of the invention consists in that the writing fluid consists by weight of 0.01 to 50.00 parts by weight of dye and / or organic and / or inorganic pigment, 5.00 to 70.00 parts of compositions against premature drying of the writing fluid, preferably from a set of alcohols , in particular aliphatic alcohols, ether alcohols, diether alcohols, polyhydric alcohols and ether diols, in particular polyhydric alcohols, most often ethylene glycol and / or diethylene glycol and / or triethylene glycol and / or monopropylene glycols and / or glycerol, the remainder being up to 100.00 parts distilled and and / or the deionized water and writing fluid further comprises, based on the weight of the fluid as a whole, 0.001 to 10.00 parts of an adduct of higher aliphatic alkylamines with oxirane having 11 to 22 carbon atoms in alkyl of about up to 20 oxirane groups or mixtures thereof and / or alkyl- or aralkyl esters of higher saturated or unsaturated fatty acids with 11 to 20 carbon atoms in the acid molecule, with 4 * to 10 carbon atoms in the alkyl or 7 to 10 and carbon atoms in aralkyl or mixtures thereof and / or sulfated higher hydroxyalkyl or alkenyl acid having 11 to 20 carbon atoms in alkyl or alkenyl or mixtures thereof.

By using these substances, it is achieved that colored stains from writing fluids from textiles, hands, etc. can be easily removed, while ordinary washing and detergents are sufficient to remove them, and soiling is removed without a trace.

It has been found to combine these substances with surfactants, which further reduce the surface tension of writing fluids and improve their function in writing aids.

In particular, depending on the type of dyes used, both cationic and anionic or nonionic surfactants can be used, also in an amount of 0.001 to 10.00 parts by weight of the writing fluid as a whole. When choosing a combination, of course, the nature of the substance chosen to achieve easy removal of colored stains of writing fluids from said materials must also be taken into account. .

In particular, the combination with sodium and / or potassium and / or ammonium dialkyl sulfosuccinate having an alkyl carbon number of 8 to 18 or mixtures thereof has proved successful.

Furthermore, the combination with N, N-dialkyl-N-hydroxyalkyl-N- (2-hydroxy-4-oxa-alkyl) ammonium chloride and / or alkyl- and alkenyldimethylamine oxide and / or alkyl- and alkenylbetaine and / or alkylpolyglycol ether monoester of disodium succinate has proved successful. optionally potassium and / or ammonium and / or alkyl polyglycol ether of sodium or potassium and / or ammonium sulfate.

Thus, the overview of the possibilities of using combinations with other surfactants is far from exhausted, essentially any surfactant can be used, both cationic and anionic or nonionic, the condition of which is its good compatibility with the writing fluid environment in which it is used sufficient reduction of surface tension. . ‘
