An etch resistant thermally curable Underlayer for use in a multiplayer liyhographic process to produce a photolithographic bilayer coated substrate, the composition having:
(a) at least one cycloolefin polymer comprising at least one repeating unit of Structure (I), and at least one repeating unit of Structure (II), and optionally at least one repeating unit of Structure (III) with the proviso that neither Structure (I) nor Structure (II) nor Structure (III) contains acid sensitive groups.
b) at least one cross-linking agent selected from the group consisting of an amino or phenolic cross-linking agent;
c) a least one thermal acid generator (TAG);
d) at lest one solvent; and
e) optionally, at least one surfactant.
