Title
(EN) OIL-BASED INK COMPOSITION FOR WRITING UTENSIL
(FR) COMPOSITION D'ENCRE À BASE D'HUILE POUR UN INSTRUMENT D'ÉCRITURE
(JA) 筆記具用油性インキ組成物
Abstract
(EN)
An oil-based ink composition for writing utensils which contains a soluble gellant and, despite this, can have improved ink storage stability while retaining leveling properties. The oil-based ink composition for writing utensils comprises a colorant, a resin, an organic solvent, and gellants, wherein the organic solvent comprises at least one organic solvent selected among hydrocarbon solvents, especially from the group consisting of aliphatic hydrocarbon solvents, alicyclic hydrocarbon solvents, aromatic hydrocarbon solvents, and halogenated hydrocarbon solvents and the gellants comprise a soluble gellant which is soluble in the organic solvent and an insoluble gellant which is insoluble in the organic solvent, the insoluble gellant being a urea-modified thixotropic agent.

Composition d'encre à base d'huile pour des instruments d'écriture, laquelle contient un gélifiant soluble et, malgré ceci, peut avoir une meilleure stabilité au stockage de l'encre tout en conservant des propriétés d'égalisation. La composition d'encre à base d'huile pour des instruments d'écriture comprend un colorant, une résine, un solvant organique et des gélifiants, ledit solvant organique comprenant au moins un solvant organique sélectionné parmi des solvants hydrocarbonés, en particulier dans le groupe constitué de solvants hydrocarbonés aliphatiques, de solvants hydrocarbonés alicycliques, de solvants hydrocarbonés aromatiques et de solvants hydrocarbonés halogénés, et lesdits gélifiants comprenant un gélifiant soluble qui est soluble dans le solvant organique et un gélifiant insoluble qui est insoluble dans le solvant organique, le gélifiant insoluble étant un agent thixotrope modifié par de l'urée.
