A method for producing a predetermined resist pattern on e.g. a lithographic printing plate, circuit board or mask, comprises the patternwise exposure to heat of a composition which comprises a novolac resin, a latent Bronsted acid and optionally a pigment. The composition is rendered preferentially soluble to a developer, in the regions which were heated.
