Abstract: front page image
(EN)Disclosed is a cyan toner having excellent light-transmitting properties which is higher in brightness and more greenish in hue than conventional cyan toners. The cyan toner contains, as a coloring material, a triphenylmethane dye compound represented by the formula (1) and having an -SO2NR9R10 group in toner particles. In this connection, R9 and R10 independently represent a hydrogen atom, an alkyl group, an aryl group or an aralkyl group, or R9 and R10 may form a heterocyclic ring together with a nitrogen atom.
(FR)La présente invention a trait à une poudre imprimante cyan possédant d'excellentes propriétés de transmission de la lumière, qui présente une luminosité plus élevée et un ton plus verdâtre que les poudres imprimantes cyan classiques. La poudre imprimante cyan contient, à titre de matière colorante, un composé de colorant triphénylméthane représenté par la formule (1) et comportant un groupe -SO2NR9R10 dans des particules de poudre imprimante. Dans ladite formule, R9 et R10 représentent indépendamment un atome d'hydrogène, un groupe alkyle, un groupe aryle ou un groupe aralkyle, ou R9 et R10 peuvent former un noyau hétérocyclique conjointement avec un atome d'azote.
