FIELD: chemistry.
SUBSTANCE: invention relates to compositions for marking substrates. The invention describes a composition for marking substrates, which contains 0.01-50 wt % colourant, 0.01-50 wt % metal salt and carboxylic acid, 1-80 wt % binder and 1-99 wt % organic solvent. Also described is a method of preparing the said composition, a substrate coated with the said composition and a method of marking substrates using the said compositions. The disclosed composition is based on using readily accessible carboxylic acid salts which can not be coloured before exposure to effects of energy.
EFFECT: composition enables to obtain semi-transparent or transparent coatings with high intensity and brightness.
