Claim:
An underlayer coating composition comprising a polymer, where the polymer comprises at least one hydroxyaromatic unit in the backbone of the polymer comprising a fluoro or iodo moiety, and at least one unit comprising an aminoplast, further where the hydroxyaromatic unit with the fluoro moiety has structure (1), where, R 1 is fluoro moiety, R 2 is fluoro moiety and R 3 is selected from a group consisting of an iodo moiety, a fluoro moiety, hydrogen, hydroxyl, (C 1 -C 4 )alkyl, hydroxy(C 1 -C 4 )alkyl, OC 1 -C 4 alkyl, (C═O)(C 1 -C 4 )alkyl, C 1 -C 4 alkylO(C 1 -C 4 )alkyl, C 1 -C 4 alkyl(C═O)(C 1 -C 4 )alkyl and C(O)O(C 1 -C 4 )alkyl.
