The invention relates to the use of 4-oxo-4H-pyran- or 4-oxo-l,4-dihydropyridine derivatives as protein-adhesive active substances, in particular as skin or hair-adhesive and/or skin or hair-binding UV-absorbers, and to the protection of the skin, hair or nails from damage caused by ultra violet radiation, especially 4-oxo-4H-pyran- or 4-oxo-1,4-dihydropyridine derivatives. The invention also relates to the use thereof and preparations containing said derivatives. The invention also relates to the use of the structural unit 4-oxo-4H-pyran-3-O-yl or 4-oxo-1,4-dihydropyridine-3-O- yl as a linker for the functionalisation of protein-containing matrices |
