| 发明名称 | Paper that cannot be forged using solvents | ||
| 摘要 | The present invention relates to a security paper that cannot be forged with respect to forgery attempts with non-aqueous solvents, characterized in that it comprises on its surface and/or in its bulk, clusters formed of elementary particles that are both insoluble in water and in solvents, amalgamated with an agglomerating agent that is also insoluble in water but almost instantaneously soluble in at least one non-aqueous solvent so as to release said elementary particles in the paper, which elementary particles are preferably less than 20 μm, and more preferably still less than 10 μm, they are colored and are advantageously intense pigment dyestuffs such as those used for producing inks or paints. | ||

| 主权项 | 1. A security paper that cannot be forged with respect to forgery attempts with non-aqueous solvents, comprising on its surface and/or in its bulk, clusters formed of elementary particles amalgamated with an agglomerating agent that is insoluble in water but almost instantaneously soluble in at least one non-aqueous solvent, which agglomerating agent is present in a maximum proportion of 40% by dry weight in the clusters, said elementary particles are coloured pigments, are insoluble both in water and in non-aqueous solvents, and have sizes of less than 20 μm. | ||
