摘要

PROBLEM TO BE SOLVED: To provide a method for measuring an average particle diameter and a normalized dispersion value of not only primary particles, but high-order particles such as secondary particles or tertiary particles of organic pigment and to provide a method for measuring a volume fraction of the primary particles and the high-order particles.;SOLUTION: An average particle diameter and a normalized dispersion value of not only primary particles, but high-order particles such as secondary particles or tertiary particles of organic pigment are measured by utilizing super small angle X-ray scattering measurement. In addition, volume fraction of the primary particles and the high-order particles are measured. Furthermore, even when the organic pigment is at states of powder, fluid dispersion, a printed matter, and a coated film, particle diameter physical property values such as the average diameter, the normalized dispersion value, and the volume fraction of the primary particles and the high-order particles of the organic pigment are measured.;COPYRIGHT: (C)2013,JPO&INPIT
