PURPOSE:To provide the title compsn. which gives a coating film having excellent physical properties and can form a durable hydrophilic film at low cost, by reacting a film-forming org. polymer resin, water-dispersible silica and a compd. in the presence of an organotitanium compd. CONSTITUTION:100pts.wt. water-soluble or watler-dispersible film-forming org. polymer resin (A) (e.g. acrylic resin), 5-100pts.wt. water-dispersible silica (B) (e.g. colloidal silica) and 5-50wt% at least one compd. (C) selected from among dialkyl sulfosuccinate salts, alkyldiphenyl ether disulfonate salts, acetylene glycol surfactant, polyoxyethylenesorbitan fatty esters and alkylene oxide silane surfactants, are reacted in the presence of 0.5-10pts.wt. (per 100pts.wt. of the combined quantity of components A and B) organotitanium compd. (D) (e.g. tetraisopropyl titanate) at room temp. to 90 deg.C for 0.5-7hr.
