  • Publication number: 20210071015
    Abstract: A technical problem of the present invention is to provide a condensed polycyclic organic pigment having excellent dispersion properties and dispersion stability. More specifically, the technical problem of the present invention is to provide a condensed polycyclic organic pigment in which a practically sufficient viscosity is achieved in terms of both the initial viscosity of a base ink and the viscosity over time of a base ink when used in the printing ink application. As a result of thorough studies on the surface state of organic pigment particles and interaction among components constituting a printing ink, it has been found that the technical problem can be solved by using a polyvalent metal inorganic salt in a condensed polycyclic organic pigment, thus accomplishing the present invention.
