Photographic elements containing loaded ultraviolet absorbing polymer latex |
摘要 |
<p>A photographic element comprising a UV absorbing polymer latex which is loaded with a non-polymeric UV absorbing compound. The polymer is a homopolymer or heteropolymer comprising monomeric units containing a 2-hydroxybenzotriazole. The benzotriazole preferably is of the formula I: <CHEM> wherein: the phenyl ring and benzo ring are optionally additionally substituted; and one of m and n is 1, and M and N have the formula: <CHEM> wherein R3 is H or an alkyl group; L is a bivalent linking group; and p is 0 or 1. The elements may additionally have a polmer present (which is preferably different from the UV absorbing polymer) which has a glass transition temperature (Tg) of less than 5 DEG C.</p> |
