Treatment composition (I) for supports such as papers, boxes, films and complexes to make authenticated, non-reproducible by photocopies and non-scannable, comprises at least one binder and a vehicle, where the composition is characterized by the presence of at least one bottom element, which is distributed homogeneously in (I), where the element is soluble in (I) or finely dispersed so as to form a united visual effect in daylight or under special lighting and at least one category of particles randomly distributed during the deposition of (I) to a substrate. Treatment composition (I) for supports such as papers, boxes, films and complexes to make authenticated, non-reproducible by photocopies and non-scannable, comprises at least one binder and a vehicle, where the composition is characterized by the presence of: at least one bottom element, which is distributed homogeneously to make (I) as authenticated, non-reproducible by photocopies and non-scannable, where the element is soluble in (I) or finely dispersed so as to form a united visual effect in daylight or under special lighting, and has average size of less than 30 mu m when in a dispersion; and at least one category of particles randomly distributed during the deposition of (I) to a substrate size of 30-500 mu m to make an effect of authenticated, non-reproducible by photocopying and non-scannable and visually directly perceptible on the bottom, daylight or under a special lighting, where either the bottom element or the category of particles are visible in daylight without equipment to confirm the presence of (I) on a support. |
