FIBROUS POLYMER FOR PAPER PROTECTION AGAINST COUNTERFEIT, METHOD OF ITS PRODUCTION, PAPER PROTECTED AGAINST COUNTERFEIT INCLUDING SAID MATERIAL AND ARTICLE (IMPORTANT DOCUMENT) Russian patent published in 2015 - IPC D21H21/30 B42D25/29 B42D25/355 B42D25/40

Abstract RU 2568707 C1

FIELD: physics.

SUBSTANCE: fibrous material is composed of the mix of separate polymer 0.1-10 mcm diameter fibres containing luminophor and arbitrarily interwoven micro fibres as separate fibrous particles of linear sizes of up to 200 mcm. Preferably, this material contains organic and/or inorganic UV- or IR-luminophor that acquires the luminescence colour under UV radiation at temperature variation. Fluorescent semiconductor nanoparticles can be used as said luminophor. Claimed material is produced by electrostatic moulding from fibre-forming polymer solution in organic solvent containing luminophor. Then, fibres are minced in water to dispersion of micro fibres. Invention discloses also the claimed paper protected against counterfeit comprises abode described fibrous material and the article thereof.

EFFECT: better protection, higher strength and wear resistance.
