POLYMER SUPPORT FOR OBTAINING POLYMER SECURITIES OR POLYMER SECURITY DOCUMENTS Russian patent published in 2023 - IPC B42D25/36 

FIELD: printing materials.

SUBSTANCE: polymer substrate (1) for producing polymer securities (2) or polymer security documents (3), to polymer security paper (2) or polymer security document (3), as well as to a method for producing polymer substrate (1). Polymer substrate (1) includes polymer support layer (4) and at least one security element (5), wherein security element (5) is applied to and/or inserted into polymer support layer (4), wherein primer (6) is applied to first side (7) of the substrate and/or second side (8) of the substrate of the polymeric substrate (1), at least in certain areas. Primer (6), at least in certain areas, is placed between polymer supporting layer (4) and protective element (5), and/or covers protective element (5) and/or polymeric supporting layer (4), at least in separate areas, and the areas of protective element (5) coated with primer (6) are less distinguishable than the areas of protective element (5) that are not coated with primer (6) and/or than the areas of polymer carrier layer (4) that are not coated with primer (6).

EFFECT: ability to provide the user with high protection against tampering.
