  2,5-di(p-methoxyanilino)terephthalic acid crystal types I and II are made by controlling the pH during the recovery of the oxidized product of the condensation of dimethylsuccinyl succinate with p-methoxyaniline. The resulting 2,5-di(p-methoxyanilino)-terephthalic acid can be converted into 2,9-dimethoxyquinacridone or a solid solution thereof having controlled characteristics.

  A medium is selective, both initial viscosity and temporal viscosity are high particularly as an NC flexographic ink depending on a system of a printing ink or paint, and an effect has not been sufficient. Provided are a quinacridone pigment composition which is suitable for printing inks, paints, and the like and which is excellent in fluidity (initial viscosity, temporal viscosity) and an ink composition containing the same. It has been found that pigment more improved in fluidity (initial viscosity, temporal viscosity) than conventional techniques is obtained by using a specific quinacridone pigment composition for quinacridone pigments, leading to the completion of the present invention.
