A marking liquid which contains a polymer dispersion with particles which are colored with marking agent, optionally further dyes and marking agents, one or more salts of a polyvalent, in particular bi- or trivalent cation, water and optionally moisture retaining agents and further usual additives, wherein the polymer forming the polymer particles is selected from the group of polyesters, polyester amides, polymers and copolymers based on acrylate or methacrylate with a proportion of free carboxylic acid groups of less than 10% by weight, melamine-formaldehyde-sulfonamide resins and mixtures thereof.

Marking liquid

The invention relates to a marking liquid which contains a polymer dispersion with particles which are colored with marking agent, optionally further dyes and marking agents, one or more salts of a polyvalent, in particular bi- or trivalent cation, water and optionally moisture retaining agents and further usual additives, wherein the polymer forming the polymer particles is selected from the group of polyesters, polyester amides, polymers and copolymers based on acrylate or methacrylate with a proportion of free carboxylic acid groups of less than 10% by weight, melamine-formaldehyde-sulfonamide resins and mixtures thereof.

A marker pencil comprises a gel-like water-bearing pencil material enclosed in a casing and incorporating a dye carrier. The structure-forming constituents of the pencil material include water-soluble metal soaps and saccharides and/or polyols derived therefrom by reduction. As a further alternative constituent the pencil material may include a fatty substance.

Marker pencil

A marking fluid based on an aqueous solution of hydroxyprene trisulfonic acid as a fluorescence dyestuff and having a pH-value in the alkaline range. The marking fluid further includes at least one mono, oligo or polysaccharide, or a polyol derived therefrom by reduction, or a mixture thereof, to improve the properties of the fluid in a number of respects. The marking fluid can be used on a wide range of different surfaces and affords improved fastness in relation to light.
