Abstract: A polymerizable anti-scratch coating composition comprising at least one alkoxysilane and/or a hydrolyzate of it, anisotropic particles of one or more metal oxides and/or oxyhydroxides with a principal axis D1 of length 400 nm or less and, transversely to it, a minimum dimension D2 and a maximum D3 such that D3 is greater than or equal to D2, D1/D2 = 11or more and D1/D3 = 10 or more and optionally a polymerization catalyst. Independent claims are included for (1) a substrate coated by deposition and hardening of the claimed composition; (2) the particles as defined in the main and dependent claims.
