FIELD: paper.
SUBSTANCE: protected substrate is intended for production of valuable document, such as banknote, passport, bond, certificate, voucher or other valuable documents. Protected substrate contains fibrous substrate and protective device. Protective device contains at least partially light-transmitting polymer bearing layer, which bears the first protective criterion. Substrate is provided with the second protective criterion. The first and second protective criteria have such shape and mutual location so that when one side of protected substrate is looked at in passing light, the first and second protective criteria visually interact to form the first composite image that is not visible in reflected light.
EFFECT: improved protective properties.
