| titleOfInvention | PROCEDURE FOR OBTAINING A SECURED PAPER |
| abstract | The invention relates to a process for producing secure paper, which includes a securing feature. The process consists in forming wet paper, incorporating therein one or more securing features, applying a glue agent on paper, and applying it to one or both sides of the paper treated with the glue agent coating composition containing a non-pigmented polyurethane. Unpigmented polyurethane may optionally contain a functional additive, provided that the presence of the functional additive does not increase the paper opacity by more than 1%. After the polyurethane is applied, the paper is dried. The coating composition forms a film when cast on a glass surface with a Konig hardness of 15 ... 130 s and passing the water resistance test defined by the following steps: a) the entire coating composition is pourable on a glass plate so as to obtain a film with a dry weight of 80 g / m 2; b) the film is initially dried at 23 ° C and is no longer sticky for another hour at 80 ° C; c) the film is weighed before it has been wetted and tested for traction and Young Modulation and visually check its transparency; d) a film sample is boiled in water containing 10 g / l NaCO 30 min; e) the film is then rinsed with cold water and steps b) and c) are repeated; when the film is dry and rewound it meets the following criteria; i) the tensile strength and Young modulus of the boiled film are 90 to 10% of the initial traction resistance and Young wet film modulus; ii) the film exhibits no perceptible loss of transparency, and iii) the weight of the dry film is 98 ... 100% of the initial weight. |
