Claim 0:
1. A compound of formula (I):, wherein:
R1, R2, R3 and R4 are each, independently of each other, chosen from the group consisting of: H; a linear or branched alkyl group comprising from 1 to 20 carbon atoms; and a group —C(O)—X—R9 wherein:
X represents an oxygen atom or a radical NR10;
R9 is chosen from the group consisting of a linear or branched, aliphatic or cyclic alkyl group comprising from 1 to 60 carbon atoms, said alkyl group possibly being interrupted with one or more heteroatoms chosen from O and S, said alkyl group possibly comprising one or more unsaturations; an aryl group comprising from 6 to 24 carbon atoms; and an arylalkyl group in which the alkyl group comprises from 1 to 12 carbon atoms;
R10 is chosen from the group consisting of: a hydrogen atom, a linear or branched, aliphatic or cyclic alkyl group comprising from 1 to 60 carbon atoms, said alkyl group possibly being interrupted with one or more heteroatoms chosen from O and S, said alkyl group possibly comprising one or more unsaturations; an aryl group comprising from 6 to 24 carbon atoms; and an arylalkyl group in which the alkyl group comprises from 1 to 12 carbon atoms;

R5 represents a hydrogen atom, a linear or branched, cyclic or aliphatic alkyl radical comprising from 1 to 20 carbon atoms, or a radical —R6—SiR7p(OR8)3−p;
R6 represents a linear or branched, cyclic or aliphatic alkylene radical comprising from 1 to 12 carbon atoms;
R7 represents a linear or branched, cyclic or aliphatic alkyl radical comprising from 1 to 12 carbon atoms;
each R8 represents, independently of each other, a linear or branched, cyclic or aliphatic alkyl radical comprising from 1 to 12 carbon atoms; or two radicals R8 may together form a ring comprising from 3 to 12 carbon atoms; and
p represents 0, 1 or 2;

wherein a radical from among the radicals R1, R2, R3 or R4 represents a group —C(O)—X—R9.
