Title:
PIGMENT-CONTAINING SOLID MATERIAL AND METHOD FOR MANUFACTURING PIGMENT-CONTAINING SOLID MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/039160
Kind Code:
A1
Abstract:
This pigment-containing solid material (1) comprises a pigment (10) and a matrix (20). The matrix (20) is formed by silica and polysilsesquioxane and coats the pigment (10). An absorption intensity deriving from a hydrocarbon group that is not directly bound to a silicon atom, an absorption intensity deriving from a bond between a silicon atom and a non-reactive functional group, and an absorption intensity deriving from a bond between a silicon atom and a hydroxy group, which are determined by means of infrared spectroscopy by the KBr pellet method using a Fourier transform infrared spectrophotometer, are respectively Ia, Ib, and Ic. The pigment-containing solid material (1) satisfies at least one of conditions Ib/Ia≥1.1 and Ib/Ic≥0.6.
