Title
(EN) DISAZO PIGMENT, PIGMENT COMPOSITION, AND PRINTING INK
(FR) PIGMENT DISAZOÏQUE, COMPOSITION DE PIGMENT ET ENCRE D'IMPRESSION
Abstract
(EN) A disazo pigment with high safety in which the content of chemical substances that may be harmful, in particular, in the food packaging field and the like and that may be regulated substances is reduced. A disazo pigment according to the present invention has a polychlorinated biphenyl content of less than 15 ppm and a primary aromatic amine content of less than 700 ppm. Preferably, the disazo pigment is at least one selected from a group consisting of C. I. Pigment Yellow 83, C. I. Pigment Yellow 13, and C. I. Pigment Yellow 14.
(FR) Pigment disazoïque très sûr dans lequel la teneur en substances chimiques pouvant être nocives, en particulier dans le domaine des emballages alimentaires et similaire, et pouvant être des substances réglementées, est réduite. Un pigment disazoïque selon la présente invention présente une teneur en biphényle polychloré inférieure à 15 ppm et une teneur en amine aromatique primaire inférieure à 700 ppm. Le pigment disazoïque est, de préférence, au moins un pigment choisi dans un groupe constitué par le pigment jaune CI n° 83, le pigment jaune CI n° 13 et le pigment jaune CI n° 14.
