R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 , which are identical or different, represent:
a hydrogen or halogen atom; or
a radical comprising from 1 to 22 carbon atoms chosen from alkyl, alkenyl, alkoxycarbonyl, alkenyloxycarbonyl, alkylcarbonyloxy or alkenylcarbonyloxy, it being possible for the hydrocarbon chain of the said radical to be optionally interrupted by at least one oxygen atom or one sulphur atom; in addition:
at least one of the R 1 to R 8 groups can form, with at least one other of the R 1 to R 8 groups and with the carbon atom or atoms to which the said groups are connected, a saturated or unsaturated hydrocarbon ring or heterocycle which is optionally substituted and which comprises from 3 to 10 ring members; and
at least one of the pairs (R 1 , R 2 ), (R 3 , R 4 ), (R 5 , R 6 ) and (R 7 , R 8 ) can form, with the carbon atom to which the said pair is connected, a carbonyl C═O group or a group of 2 carbon atoms connected by a double bond: C═C, the other carbon atom of which carries 2 substituents chosen from a hydrogen atom or a C 1 -C 4 alkyl radical;

x and y are integers, which are identical or different, within a range extending from 0 to 6, the sum x+y being within a range extending from 0 to 6;
