The lower layer composition comprises at least one organosilane, or hydrolysate thereof of formula R'n'Y'm'Si(X')4-n-m' and, optionally at least one compound, or hydrolysate thereof of formula M'(Z')y, the following ratio being greater than 2.3 : Ri = mass of the theoretical dry extract of compounds III in the lower layer composition/mass of the theoretical dry extract of compounds IV in the lower layer composition. In the above formulae, M and M' are metals or metalloids of valence x and y, at least equal to 4, R and R' are monovalent organic groups bonded to silicon by a carbon atom and containing at least one epoxy function, groups X, X', Z and Z' are hydrolysable groups, Y and Y' are monovalent organic groups bonded to silicon by a carbon atom, n, m, n' and m' are whole numbers such that n and n' = 1 or 2 with n+m and n'+m' = 1 or 2.
