Abstract:
A silicone-substituted cinnamamide, benzalmalonamide or benzalmalonate compound having one of the following structural formulae (1) or (2): ##STR19## in which the radicals R, which may be identical or different, are each a saturated or unsaturated, linear or branched C.sub.1 -C.sub.10 alkyl radical, a phenyl radical or a 3,3,3-trifluoropropyl radical, at least 80% by number of the radicals R being methyl radicals; the radicals B, which may be identical or different, are each a radical R or a radical A; r is an integer ranging from 0 to 3, inclusive; s is 0 or 1 and if s is 0, at least one of the two radicals B is A; u is equal to 1 or 2; t is an integer ranging from 2 to 5 inclusive; t+u is greater than or equal to 3; and A is a radical of formula (3) below: ##STR20## wherein R.sub.1 is a linear or branched C.sub.1 -C.sub.10 alkoxy radical, a linear or branched C.sub.1 -C.sub.10 alkyl radical, a linear or branched C.sub.2 -C.sub.8 alkenyl radical or a radical --OSi(CH.sub.3).sub.3, with the proviso that two adjacent radicals R.sub.1 may together form an alkylidenedioxy radical in which the alkylidene radical has from 1 to 2 carbon atoms, n is 0, 1, 2 or 3, Z is hydrogen, a C.sub.1 -C.sub.4 alkyl radical, a radical --(C.dbd.O)XR.sub.2 or a radical --(C.dbd.O)YW, X and Y, which may be identical or different, are each an oxygen atom or a radical --NR.sub.3, W is a saturated or unsaturated, linear or branched C.sub.1 -C.sub.6 alkanediyl radical, optionally substituted with a hydroxyl or saturated or unsaturated, linear or branched C.sub.2 -C.sub.8 alkyl radical, R.sub.2 is, independently, a C.sub.1 -C.sub.12 alkyl radical, R.sub.3 is, independently, hydrogen or a linear or branched C.sub.1 -C.sub.8 alkyl radical, with the proviso that R.sub.2 and R.sub.3 may together form a heterocycle, with the added proviso that when Z=H, then X is the radical --NR.sub.3 --.
