Silicone compositions that are cationically crosslinkable into hard, anti-mist/anti-fouling coatings, e.g., onto thermoplastic substrates, contain colloidal particles of non-functionalized silica and also: at least one crosslinkable and/or polymerizable silicone monomer, oligomer and/or polymer comprising: at least one structural unit of formula (I): <?in-line-formulae description="In-line Formulae" end="lead"?>Z<SUP>1</SUP>(R<SUP>0</SUP>)<SUB>a</SUB>SiO<SUB>(3-a)/2 </SUB> (I) <?in-line-formulae description="In-line Formulae" end="tail"?> in which: a=0, 1 or 2; the radicals R<SUP>0</SUP>, which may be identical or different when a>1, are each an alkyl, cycloalkyl, aryl, vinyl, or alkoxy radical, or a hydrogen atom; the radicals Z<SUP>1</SUP>, which may be identical or different when the number of units of formula (I) is greater than 1, are each an organic substituent comprising at least one epoxy and/or alkenyl ether and/or oxetane and/or dioxolane and/or carbonate reactive functional group; and a total number of silicon atoms per molecule at least equal to 2; and an effective amount of at least one cationic initiator; and optionally, at least one organic solvent.
