(Natsionalnyi tekhnichnyi universytet Ukrainy «Kyivskyi politekhnichnyi instytut» (Kyiv, Ukraina) Research of the printing properties of formaldehyde free banknote paper. — 2013. — № 3(41). — pp. 4–11.

This topic is extremely important, because paper is one of the basic consumable materials which are used for products printing. Properties of banknotes paper should provide stability of reproduction of the printed image. At the same time the cost of the paper manufacturing must be reduced providing preservation of printing properties at the appropriate level, which will ensure the quality of the banknotes.
Nowadays, for banknotes printing process the paper on melamine-formaldehyde basis is used. However, formaldehyde belongs to the third class of hazardous substances, is a strong allergen and a carcinogen, and causes irritation of the skin and mucous membranes. Evaporation of formaldehyde is hazardous both for health of manufacture employees and, according to the latest data, for users of products, which contain formaldehyde.
Objectives of the research: is analyze and comparison of printing properties of banknote paper with formaldehyde free sizing and paper with melamine-formaldehyde sizing.
Scientific result is the determination of the difference between linear deformation of formaldehyde free types of paper and tirage paper (with melamine-formaldehyde sizing).
Key words: banknotes, banknote paper, linear deformation, melamine-formaldehyde paper, formaldehyde free paper, optical density, sizing, melamine, formaldehyde, polyamide-epichlorohydrin.
