An antistatic sol/gel forming coating composition comprising: (a) a hydrolyzate resulting from the at least partial hydrolysis of a component A consisting of one or more compounds containing at least one polyalkylene oxide segment and at least one -Si n hydrolyzable group, preferably at least two, and more preferably 2, in which n is an integer ranging from 1 to 3, and the X groups, identical or different, represent precursors of OH groups; (b) optionally, at least one component B consisting of one or more compounds of formula: R n' Si 4-n' or a hydrolyzate thereof, in which the R groups, identical or different, represent monovalent alkyl groups, the Z groups, identical or different, represent hydrolyzable groups or hydrogen atoms, and n' is an integer equal to 0, 1 or 2, preferably 0, with the proviso that the Z groups do not all represent an hydrogen atom when n' = 0, and preferably do not all represent a hydrogen atom, and/or one or more compounds of formula: R 1 n1 Y m1 Si(Z 1) 4-m-m1 or a hydrolyzate thereof, in which the R 1 groups, identical or different, represent monovalent organic groups linked to the silicon atom through a carbon atom, the Y groups, identical or different, represent monovalent organic groups linked to the silicon atom and containing at least one epoxy function, the Z 1 groups, identical or different, represent hydrolyzable groups or hydrogen atoms, m1 and n1 are integers such that m1 is equal to 1 or 2 and n1+m1 = 1 or 2; c) at least one inorganic metal salt; and component A and optional component B being chosen such that a cross-linked structure is generated upon polymerization of said composition, the dry extract, determined in accordance with indications given in the description, of said composition containing less than 5% by weight, preferably less than 2% by weight, more preferably less than 1% by weight, better less than 0.5% by weight of free polyalkylene oxide polymers, and most preferably being totally devoid of free polyalkylene oxide polymers.
