Patent

CA 2470741

A pigment composition composed of 50 to 95 % by weight of a phthalocyanine, 1 to 45 % by weight of a halogenated phthalocyanine of which the number of substituents of a halogen atom is 1 to 9 and the average number of the substituents is 2.0 to 4.0 and 0.1 to 10 % by weight of a phthalocyanine derivative of the formula (1) or a phthalimide methylated phthalocyanine derivative, a colorant containing the above pigment composition and a molded article obtained from a plastic containing the above colorant, P-(X)m (1) wherein P represents a phthalocyanine structure, X represents an alkyl group having 12 to 18 carbon atoms, an alkoxy group having 12 to 18 carbon atoms, -SO2NHR, -SO2NR2, -NR2, -CONR2, -CONHR or -SR (wherein R represents an alkyl group or an alkenyl group which has 12 to 18 carbon atoms), and m is an integer of 1 to 4.

Divulgation d'une composition de pigment comprenant de 50 à 95 % en poids d'une phtalocyanine, de 1 à 45 % en poids d'une phtalocyanine halogénée dont le nombre d'atomes d'un halogène substituant est de 1 à 9 et le nombre moyen de substituants est de 2,0 à 4,0 et de 0,1 à 10 % en poids d'un dérivé de phtalocyanine de formule (1) ou d'un dérivé de phtalocyanine méthylée phtalimidique, d'un colorant contenant ladite composition de pigment et d'un article moulé obtenu à partir de matière plastique contenant ledit colorant P-(X)m (1) dans lequel P représente une structure de phtalocyanine, X représente un gourpe aklyle ayant de 12 à 18 atomes de carbone, un groupe alcoxy ayant de 12 à 18 atomes de carbone, -SO2NHR, -SO2NR2, -NR2, -CONR2, -CONHR or -SR (dans laquelle R représente un groupe alkyle ou alcényle ayant de 12 à 18 atomes de carbone) et m est un nombre entier de 1 à 4.
