METHOD OF PRODUCING POLYMER LAYER WITH LATENT POLARIZED IMAGE

摘要

The invention related to polygraphy , and in particular to the production of polymer layers documents, security papers, banknotes as well as for manufacturing of excise documentary stamps, labels, tags and other products of the kind. A polymer layerwith a latent polarized image which is achieved by means of preparing a polymer solution in an organic dissolvent, the application of the said solution on a light - reflecting substrate, further drying as a result producing of an optically isotropicpolymer layer and forming there on the said polymer layer of image generating areas as a result producing of an optically isotropic polymer layer and forming there on the said polymer layer of image generating areas having anisotropic properties, while the concentration of the polymer solution is from 5 to 30 % and the areas having anisotropic properties are produced by means of application on the said polymer layer of micro-lines having the depth from 1 to 3 um and being separated from one another by the dista
