Title (EN) COLOR INK SET FOR INK-JET RECORDING
(FR) ENSEMBLE D'ENCRES COLOREES POUR IMPRESSION PAR JET D'ENCRE
Abstract:
(EN) A yellow ink composition and a magenta ink composition which satisfy the characteristics necessary as the ink for color ink-jet recording, particularly the resistance to the clogging of nozzles, and can realize printed images excellent in tone, water resistance, shelf stability and light resistance; and a color ink set comprising these ink compositions, a specific cyan ink composition, and a specific black ink. This ink set is based on a yellow ink composition containing a mixture comprising a dye of general formula (XI) and a dye of general formula (XII) (wherein R101 and R102 are each phenyl or naphthyl substituted with hydroxyl, -SO3M or -COOM; R103 and R104 are each hydrogen, alkyl or methoxyl; R105 and R106 are each hydrogen, hydroxyl or C2H4OH; R201 or R202 is phenyl or naphthyl substituted with hydroxyl, -SO3M or COOM; and R203 or R204 is hydrogen, alkyl or methoxy).
(FR) Cette invention concerne une composition d'encre jaune et une composition d'encre magenta qui possèdent les caractéristiques requises pour une encre destinée à l'impression par jet d'encre, notamment en ce qui concerne la résistance à l'obturation des buses, et qui permettent l'impression d'images d'excellente qualité en ce qui concerne les nuances, la résistance à l'eau, la durée de conservation et la résistance à la lumière. L'invention concerne aussi un ensemble d'encres colorées comprenant ces compositions d'encres, une composition spécifique d'encre cyan et de l'encre noire spécifique. La base de cet ensemble d'encres est une composition d'encre jaune qui contient un mélange comportant un colorant représenté par la formule générale (XI) et un colorant représenté par la formule générale (XII). Dans ces formules, R101 et R102 représentent chacun phényle ou naphtyle substitué par hydroxyle, -SO3M ou -COOM; R103 et R104 représentent chacun hydrogène, alkyle ou méthoxy; R105 et R106 représentent chacun hydrogène, hydroxyle ou C2H4OH; R201 ou R202 représente phényle ou naphtyle substitué par hydroxyle, -SO3M ou -COOM; et R203 ou R204 représente hydrogène, alkyle ou méthoxy.
