The invention relates to oxybenzylidenebornanones which correspond to the general formula: <IMAGE> in which Z and Z' denote hydrogen or a radical SO3H, at least one of the two radicals Z and Z' denoting hydrogen, R1 denotes hydrogen, an alkyl radical having 2 to 18 carbon atoms, an alkenyl radical having 3 to 18 carbon atoms, a radical -(CH2CH2O)nH, <IMAGE> +TR <IMAGE> -(CH2)mCO2R, in which R denotes H or an alkyl radical, -(CH2)3SO3H or a divalent radical -(CH2)m or -CH2-CHOH-CH2, m having the values 1 to 10, n having the values 1 to 20 and p having the values 1 to 6, and R3 and R4 representing hydrogen or an optionally branched or hydroxylic alkyl radical, or forming an aminoaliphatic heterocyclic ring with the nitrogen atom, R2 denotes a hydrogen atom, an alkoxy radical or a divalent radical -O- bonded to the radical R1 if the latter is also divalent, and q denotes 1 or 2; if q has the value 2, R1 is a divalent radical, and, if R1 denotes hydrogen, R2 also denotes hydrogen. These compounds can be used in cosmetic compositions for providing protection against actinic rays.
