Abstract	Silica sol doped with organic pigment was prepared by hydrolyzing tetraethoxysilane with a basic catalyst via dispersing pigment in silica sol. The colloidal properties of SiO$_{2}$/pigment hybrid sol and its deposited film were investigated. The presence of pigment in SiO$_{2}$/pigment hybrid sol affects the Zeta potential, particle size and surface tension compared to the silica sol without pigment. The SiO$_{2}$/pigment hybrid sol exhibited good dispersion stability in the centrifuge process. The maximum absorption wavelength was consistent with that of the pigment disperse solution, indicating that the pigment in SiO$_{2}$/pigment hybrid sol remained unchanged. Thermogravimetric analysis of the contents of organic component in silica sol and SiO$_{2}$/pigment hybrid sol were conducted, and the differential value was ascribed to the weight of the pigment and the condensate of polyoxyethylene octylphenol ether (OP-10) and γ-Glycidoxypropyltrimethoxysilane (KH-560). The surface topography of SiO$_{2}$/pigment hybrid silica film was characterized by AFM. The analysis of silica sol doped with organic pigment provides useful information for an effective pathway to disperse pigment on fiber and other substrates.
