Composition for forming abrasion-removable coatings

摘要

The compositions for producing abrasion-removable layers or coatings, particularly formulated as printing inks, contain a binder, a pigment, a filler and water. The compositions are free from any volatile organic compound and ammonia, water being the sole volatile species and the sole solvent and diluent. The binder is an aqueous solution or dispersion of a film-forming polymer. The compositions are before all used for producing security documents carrying valorization indicia which are to be temporarily masked.
