A water based glue stick composition includes adhesive and nanocrystalline cellulose. The composition is contained in a glue stick that can be used for planar joining of substrates to one another. The substrates can include paper and/or cardboard such as printer paper, photo paper and cardboard paper.

Glue stick composition

The present invention concerns a washable aqueous ink composition comprising: a) at least one alkali metal salt of citrate, b) at least one cyclodextrin or derivative thereof, c) at least one dye. It also concerns a writing instrument comprising it and the use of the association of a) at least one alkali metal salt of citrate and b) at least one cyclodextrin or derivative thereof, to improve the washability and/or vividness of the shades of a washable aqueous ink composition.

Washable ink composition

An aqueous peelable ink composition comprising at least one film-forming elastomeric polymer, at least one pigment, and water, wherein the film-forming elastomeric polymer is hydrogenated acrylonitrile butadiene rubber, and a method for preparing such an aqueous peelable ink composition.

Peelable ink composition for porous substrates

There is an alcohol-based dry erasable ink for writing instrument having as separating agent, more specifically as the only separating agent, a mixture of a pentaerythritol tetraester (a1), a fatty acid monoester (a2) and a fatty acid diester (a3). There also is a writing instrument having an alcohol-based dry erasable ink.

Alcohol-based dry erasable ink for writing instrument

A free-ink writing instrument mat include a nib drying delay component to prevent drying out of the end of the nib of the writing instrument that is located in the writing ink tank thereof. The nib drying delay component is locally arranged around the end of the nib in a liquid tight manner and configured to locally retain ink therein so as to keep the nib end in contact with locally retained ink.

Writing instrument

A dry erase ink for a writing instrument. The dry erase ink includes, as the main organic solvent, a solvent selected from the group consisting of n-propyl acetate, isopropyl acetate, or mixtures thereof.

Dry erase ink with improved drying time

An alcohol-based dry-erasable ink for a writing instrument including, as separation agent, a mixture of glycerol, glycol and pentaerythritol ester.

Alcohol-based dry-erasable ink

A correction fluid includes an organic solvent, a dispersing and wetting agent having a polyamine amide of polycarboxylic acid obtained by reacting a fatty acid dimer and a diamine, the fatty acid being a C14 to C22 fatty acid, an opacifier to a concentration of between 37 and 60% by weight relative to the total weight of the correction fluid, a resin, and optionally, an additive.

Correction fluid

A correcting fluid with a colored drying indicator that includes as fluorescent dye, sodium 8-hydroxy-1,3,6-pyrenetrisulfonate and a good solvent for the fluorescent dye, in which the solubility of the fluorescent dye at 20&#xb0; C. is at least equal to 0.1 g/l, and, a poor solvent for the fluorescent dye, in which the solubility of the fluorescent dye is less than or equal to 0.01 g/l at 20&#xb0; C., the poor solvent being miscible with the good solvent for the fluorescent dye.

Correcting fluid with drying indicator

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.
