Photoactivatable diazirine-active agent compounds, compositions comprising them and uses thereof

A cosmetic composition comprising,

• at least one cosmetically acceptable solvent, and
• at least one photoactivatable diazirine-active agent compound which comprises a diazirine covalently bonded to a cosmetic active agent, wherein the cosmetic agent is chosen from natural soluble polymers, synthetic soluble polymers, natural insoluble polymers, synthetic insoluble polymers, sunscreens, mineral particles, organic particles, antioxidants, and dyes, and
• wherein the diazirine is chosen from diazirines of formula (I):
• wherein:
• —R1 is chosen from a hydrogen atom, linear and branched C1 to C10 alkyl radicals, linear and branched C2 to C10 alkenyl radicals, linear and branched C2 to C10 alkynyl radicals, CF3, CCl3, CBr3, N(R′)3+, S(R′)2+, SH2+, NH3+, NO2, SO2R′, C≡N, COOH, F, Cl, Br, I, OR′, COOR′, SO3H, COR′, SH, SR′ and OH radicals, wherein R′ is chosen from C1 to C10 alkyl radicals;
• —Z is chosen from a single bond and a spacer group, wherein the spacer group is a carbon-based chain chosen from linear, branched and cyclic, saturated
• C1-C100 carbon-based chains, wherein said carbon-based chain may be interrupted with at least one hetero atom and may also comprise at least one substituent;
• —Y is an aldehyde, and
• —Ar is an aromatic nucleus:
• wherein:
• —R2, R3, R4 and R5, which may be identical or different, are each chosen from a hydrogen atom, linear and branched C1 to C10 alkyl radicals, linear and branched C2 to C10 alkenyl radicals, linear and branched C2 to C10 alkynyl radicals, CF3, CCl3, CBr3, N(R′)3+, S(R′)2+, SH2+, NH3+, NO2, SO2R′, C≡N, COOH, F, Cl, Br, I, OR′, COOR′, COR′, SH, SR′, OH and SO3H radicals, wherein R′ is chosen from C1 to C10 alkyl radicals.
