Abstract
Abstract Light-sensitive photographic material which contains as a uv-filter layer a non-light sensitive layer comprising a compound of the formula ##STR1## wherein W is the residue of an oxazolone, isoxazolone or pyrazolone ring, R 1 , R 2 and R 5 are each hydrogen or halogen or --OCOR 10 wherein R 10 is an optionally substituted alkyl or alkoxy, alkaryl or aryl, and R 3 and R 4 are each hydrogen or alkoxy. These compounds exhibit a very sharp cut-off point at about 400 nm.
