Claim 7:
8. The curable silicone composition X according to claim 1, wherein the at least one organosilicon crosslinker H-XL containing at least 3 silicon-bonded hydrogen atoms per molecule is present and comprises:
(i) at least 3 siloxy units of formula (XL-1) which may be identical or different:

(H)(Z)eSiO(3-e)/2  (XL-1)

wherein:
the symbol H represents a hydrogen atom,
the symbol Z represents an alkyl having from 1 to 8 carbon atoms inclusive, and
the symbol e is equal to 0, 1 or 2; and

(ii) at least one, and optionally from 1 to 550 of siloxy unit(s) of formula (XL-2):

(Z)g SiO(4-g)/2  (XL-2)

wherein:
the symbol Z represents an alkyl having from 1 to 8 carbon atoms inclusive, or a C6-C12 aryl group such as a xylyl, tolyl, or phenyl group, and
the symbol g is equal to 0, 1, 2 or 3;, wherein Z in XL-1 and XL-2 can be the same or different.
