Yellow pigments with safe characters, higher chroma with vivid yellowish color, higher tinting strength, and better durability are required especially in color application. We have prepared yellow composite particles consist of titanium dioxide particles coated with organic yellow, assisted by silane compounds as an adhesive agent. TEM photographs of yellow composite particles indicated that organic yellow clusters were adhered onto the titanium dioxide surface, and formed the shell with uneven shape. The performances such as chroma, tinting strength and durability of the yellow composite particles with PY110 were improved to the same or above level of conventional inorganic heavy metal particles.
