1. A blush coating composition comprising a mass of light-scattering, primary resin particles which are adapted to coalesce to a more compact coating (a) on application of heat thereto, or (b) on exposure to aliphatic or aromatic solvent, said mass of particles being in intimate contact with a minor amount of a binder composition which, on exposure to any of a wide spectrum of aromatic or aliphatic solvents, will form a means to substantially impair the light-scattering character of said mass of particles and transform said mass of particles into a more compact, normally translucent, coating.
