Abstract:
A method for producing a predetermined resist pattern on a support, the method comprising:(a) patternwise exposing a precursor to heat, the precursor comprising a coating on the support, and producing exposed regions in the coating; and (b) applying a developer to the coating and preferentially removing the exposed regions; in which the coating consists essentially of: (i) a novolac resin; (ii) optionally, an additional resin component; (iii) a latent BrÃ¶nsted acid; (iv) optionally, a pigment that absorbs radiation and converts it to heat; and (v) optionally, one or more components selected from the group consisting of stabilizing additives and inert colorants; wherein said novolac resin is present in an amount of at least 85 wt % of the total resin content of said coating.
