Beschreibung
Zusammenfassung:	Disclosed are compositions containing a UV-inhibitor, optionally a carrier, and optionally anions; wherein the UV-inhibitor is at least one compound of formula (I)wherein R1 is an aryl derivative, N-acyl, guanidine or aminoguanidine group, and R2 and R3 are independently an aryl group substituted with a straight or branched chain alkyl or an electron donating or withdrawing group. Also disclosed are methods for protecting a product from UV light, involving applying to said product, in an amount sufficient to protect said product from UV light, the composition. Furthermore, there is disclosed methods for providing a reversible dye to a product, involving applying to said product, in an amount sufficient to provide a visible color to said product, the composition.
