Abstract;Colloidal silica is well known as nano-particle, which is used for the photo like paper for ink jet printing. Cationic colloidal silica having positive .ZETA.-potential was obtained by treating the anionic colloidal silica with the amino-functional silane. By using three types of colloidal silicas, anionic colloidal silica and cationic colloidal silicas with the amino-functional silane and aluminium oxide, the performance of them for ink jet paper was investigated. In particular, the pigment inks did not run on the paper coated with the cationic colloidal silica having the amino-functional silane. It seems that the pigment ink having negative .ZETA.-potential strongly adsorbs on the cationic colloidal silica by electrostatic interaction. (author abst.)
