FIELD: methods of producing data carriers.
SUBSTANCE: method can be used for making persona; identifications in form of cards, securities etc. Method of making info carrier (1,10) provided with protective element having optically variable properties. The element has at least one distinguish marking (5, 6, 11) and at least one light-permeable layer (4) with optically variable properties. Layer having optically variable properties is at least at several parts overlapped with marking. Light-permeable layer (4) with optically variable properties is applied onto data carrier and marking (5, 6, and 11) is made through the layer onto data carrier (7) formed by means of laser radiation. Layer (4) with optically transparent properties has material, which creates optical variable effect. Moreover, the layer stays invariable under influence of laser radiation. Method provides high protection against imitation.
EFFECT: simplification; reduced cost of production.
