A wide range of chemical affinity control of pigment surface against media, such as high polar solvents including water, lower alcohols and ketones, and low polar solvents involving toluene was demonstrated by utilizing organohalosilane/halosilane containing a number of carbons from zero to 18 onto the surface of pigment. The treatment was accomplished with an environmentally friendly process while keeping the pigment particle size fine and its distribution narrow. The efficiency of the surface modification with those silanes did not show a big influence caused by varying chemical property of pigment surface. High technical feasibility of the treatment for digital imaging applications is suggested.
