According to the present invention, a resin is added to crude copper phthalocyanine comprising an .alpha.-form and a .beta.-form crystals in combination and dry-milling is performed in a deoxygenated atmosphere, to provide copper phthalocyanine pigment composition of superior quality which reduces considerable expenditure of time and labor associated with the pigmentation process of crude copper phthalocyanine and the printing ink production process of a pigment, and printing ink comprising .beta.-form copper phthalocyanine pigment superior quality.

Dans la présente invention, une résine est ajoutée à de la phtalocyanine de cuivre brute contenant des cristaux combinés de forme alpha et de forme bêta et un broyage à sec est réalisé dans une atmosphère désoxygénée pour produire une composition de pigment de phtalocyanine de cuivre de qualité supérieure qui réduit considérablement les dépenses en temps et en main-d'oeuvre liées au procédé de pigmentation par la phtalocyanine de cuivre brute; l'invention concerne également le procédé de production d'un pigment d'encre d'imprimerie ainsi que l'encre d'imprimerie contenant le pigment de phtalocyanine de cuivre de forme bêta de qualité supérieure.
