Title:
Ｃ．Ｉ．ピグメントブルー１６を含有する青色顔料組成物及びその製造方法、並びに緑色着色組成物
Document Type and Number:
Japanese Patent JP6963800
Kind Code:
B2
Abstract:
The present invention provides a blue pigment composition, which is capable of producing a highly bright green-colored composition by combining with a yellow pigment, and contains C.I. pigment blue 16 having a novel crystal structure. Furthermore, the present invention provides a highly bright green-colored composition containing the C.I. pigment blue 16 and yellow pigment composition. Between the diffraction intensity (A) of Bragg angle (2[theta]) = 7.3 DEG for X-ray with CuK[alpha] characteristic and the diffraction intensity (B) of the peak of Bragg angle (2[theta]) = 6.9 ± 0.2 DEG for X-ray with CuK[alpha] characteristic, the present invention uses a C.I. pigment blue 16 having a relationship of 0.05 ≤ A/B ≤ 0.35 and a maximum particle width of 20 nm or more and 80 nm or less.
