A polymer film comprising at least one compound represented by formula (I) is disclosed. Aand Aeach independently represent a group having a Hammett's &#x3c3;p value of 0.2 or more, or bond each other to form a cyclic active methylene structure; and Xand Xeach independently represent a hydrogen atom, aryl group, hetero-cyclic group, cyano, N-alkyl- or N-aryl-carbamoyl, or alkyl- or aryl-oxycarbonyl, or bond each other to form a saturated ring in which nitrogen and carbon atoms are embedded, and the group and ring may have at least one substituent.
