NOVEL CORRECTION COMPOSITIONS AND PROCESS FOR USING SAME ABSTRACT Correction compositions for correcting markings provided on the surface of a pressure-sensitive chemical recording medium carrying a developer material which comprises an acidic developer by interaction of the developer material with a color-providing material. The compositions comprise a substantially uniform dispersion of an opacifying pigment, a polymeric film-forming material, and a Lewis acid. The composition is applied to a marking to provide a film which covers the marking, and a visible corrected marking can be provided on the film by applying a pattern of color-providing material corresponding to the corrected marking to the film.
