Abstract
Abstract 1-Amino-4-cyano-1,3-butadiene compounds of the formula ##STR1## WHEREIN N IS 1 OR 2, WHEN N IS 1 R 1 and R 2 can be the same or different and represent hydrogen, alkyl including substituted alkyl, aryl including substituted aryl or cyclic alkyl groups, except that both R 1 and R 2 cannot be hydrogen, or taken together R 1 and R 2 represent the elements necessary to complete a cyclic amino group and when n is 2 at least one of R 1 and R 2 is alkylene or arylene; G represents an electron withdrawing group. The compounds are especially useful in photographic elements as UV absorbers.
