Abstract: The ink compositions comprise at least one solvent, at least one colorant, and at east one oil, and may be delivered from any of a variety of writing instruments including but not limited to ball pens, fountain pens, felt tip pens, and markers.

Abstract: The present invention is colored correction fluid to correct mistakes on colored paper with the colored correction fluid contained in a spray bottle and dispersed and sprayed from the bottle onto the mistakes. The colored correction fluid can be applied with a brush applicator and includes a casing and a thumb hold disposed on the casing to allow a user to better hold, grasp and direct the applicator. The colored correction fluid is contained in the casing and applied onto the mistakes using a brush. Colored correction fluid can also be removably disposed on colored correction sheet material to correct mistakes on colored paper, with colored correction material directly applied onto the mistakes. The colored correction fluid can be matched to the dye on the colored paper and is available in a variety of popular colors.

Abstract: The invention relates to aqueous pigment preparations containing (A) at least one organic and/or inorganic pigment, (B) a dispersant of formula (I) or (II), or mixtures of the dispersants of formula (I) and (II), (C) optionally wetting agents, (D) optionally other surfactants and/or dispersants, (E) optionally one or more organic solvents or one or more hydrotropic substances, (F) optionally other additives used conventionally for the production of aqueous pigment dispersions and (G) water.

Abstract: The invention relates to a pigment preparation containing (a) 50-99 percent by weight of at least one pigment, (b) 1 to 50 percent by weight of an additive based on polyalkylene glycols, and (c) 0 to 10 percent by weight of an auxiliary agent from among the group comprising fillers, fire retardants, preservatives, light-stability agents, pigmentary and non-pigmentary dispersing agents, surfactants, antioxidants, foam inhibitors, resins, and antistatic agents, the percentages being in relation to the total weight of the pigment preparation. The additive that is based on polyalkylene glycols corresponds to formula Z?-[-(AO—)n1—B-T-X—Y]m—Z (1), wherein AO represents a C2-C10 alkyleneoxy unit, B represents a C2-C10 alkylene radical, and T represents —NR—, X represents one of the groups (formula), and Y represents a chemical bond or —NR3—.

Abstract: An oil-based ink composition for writing instruments is provided that is capable of improving storage stability of an ink, while maintaining a leveling property even when a soluble gelling agent is used. The oil-based ink composition for writing instruments comprises a colorant, a resin, an organic solvent and a gelling agent, wherein said organic solvent(s) is (are) hydrocarbons solvent(s), and in particular, at least one species of the solvent selected from the group of aliphatic hydrocarbons solvent(s), alicyclic hydrocarbons solvent(s), aromatic hydrocarbons solvent(s), and halogenetad hydrocarbons solvent(s), said gelling agent(s) comprises (comprise) soluble gelling agent(s) soluble to the above organic solvent(s) and insoluble gelling agent(s) insoluble to the above organic solvent(s), and the above insoluble gelling agent(s) is (are) urea-modified thixotropic agent(s).

Abstract: A central core type marking pen which has an ink storage portion of a central core and a pen tip connected thereto, wherein the central core contains a water-based pigment-containing ink composition which contains a thickening agent and exhibits, at 20° C., a viscosity of not less than 45 mPa·s and not greater than 12 mPa·s when a stress of 0.01 and a stress of 10 Pa are applied, respectively.

Abstract: The colored liquid composition of the invention for a highlighter comprises a coloring element and water, the water content by weight lies in the range 10% to 30%. In addition, it comprises at least 40% of a liquid component having surface tension greater than 40 mN/m. In a variant, the coloring element is a tracer solvent having a fluorescent appearance under basic pH, in particular hydroxypyrenetrisulfonic acid, the pH of the composition lying in the range 8 to 9, and the component having surface tension greater than 40 mN/m is triethanolamine. Under such circumstances, the composition contains an acid to neutralize the triethanolamine in part in order to obtain the basic pH, for example hydrochloric acid.

Abstract: A composition for positive correction of lithographic printing plates, applicable by pen or by brush, is disclosed. The correction fluid contains a film forming phosphate ester and a solvent that does not dissolve image areas of the printing plate. A correction kit containing the composition and methods for correcting printing plates by additive correction are also disclosed.
