n (1) Film defect which appears as a milky opalescence as the film dries; can be a temporary or permanent condition. It is generally caused by rapid evaporation, moisture, or incompatibility. See also  Bloom. Syn:  Fog. (2) Milky opalescence which sometimes develops as a film of lacquer dries, and is due to the deposition of moisture from the air and/or precipitation of one or more of the solid constituents of the lacquer; usually confined to lacquers which dry solely by evaporation of solvent. Also applies to printing inks. (3) A white or grayish cast on high gloss paint; results from the precipitation of binder solids owing to incompatibility with water, oil, or solvent.
