Abstract

Photographic elements containing 3-tertiary alkyl group substituted 2-hydroxyphenylbenzotriazole UV absorbing polymers. In particular, a photographic element having at least one layer containing a light sensitive silver halide emulsion and at least one layer which is not light sensitive, the element having in at least one of the layers an ultraviolet absorbing polymer which includes units formed from monomers of the structure of formula (I): ##STR1## wherein: n is an integer of 1 to 6; p and m are, independently, 0 or 1; tert-Alk is a 4 to 10 carbon atom tertiary alkyl group; G is --CO--, --C(O)--, --C(O)NH--, or --SO.sub.2 --; R.sub.2 and R.sub.3 are, independently, H, halogen, alkyl group or alkoxy group, and if n is more than 1 all of the R.sub.2 may be the same or different and all of the R.sub.3 may be the same or different; the benzene ring of the benzotriazole and the phenyl ring phenol group each may be further substituted or unsubstituted; z is an arylene group, alkylene group, or alkylene group which is interrupted by O, N or a group of the type which G can represent; and Y is an ethylenically unsaturated polymerizable group.
