Title (EN) AQUEOUS PIGMENT-BASED BALL-POINT INK HAVING WHITE COLOR TONE
(FR) ENCRE POUR STYLO A BILLE A BASE D'UN PIGMENT AQUEUX DE COULEUR BLANCHE
Abstract:
(EN) An aqueous pigment-based ball-point ink having a white color tone, which has an oil absorption of not more than 25 g/100 g and comprises titanium oxide having an average particle diameter of not more than 400 nm, a water-soluble resin, a thickener, water, and a polar solvent. The ink can give drawings having intense colors, such as a white color or a poster color, independently of the color tone of writing paper, and can hide or retouch drawings printed by a writing instrument, a typewriter, a copying machine or the like.
(FR) L'invention porte sur une encre pour stylo à bille, cette encre ayant pour base un pigment aqueux de couleur blanche et dont le degré d'absorption d'huile est inférieur à 25 g/100 g. Cette encre comprend de l'oxyde de titane dont le diamètre moyen des particules est inférieur à 400 nm, une résine soluble dans l'eau, un épaississant, de l'eau et un solvant polaire. Cette encre permet de réaliser les dessins des lettres avec des couleurs intenses telles qu'une couleur blanche ou une couleur à la gouache, indépendamment du ton du papier écriture, et permet de masquer ou de retoucher les dessins des lettres réalisés par un instrument d'écriture, une machine à écrire, une machine à photocopier ou autre.
