FIELD: identification marks.
SUBSTANCE: invention relates to identification marks which can be used as devices providing identification of goods or articles, in particular can be used in making sheet material, such as banknotes, securities, documents in order to establish their authenticity. Elimination of labels corrosion and high and stable signal response of the mark is achieved by using a cobalt-based alloy with near-zero magnetostriction at a ratio of Co to Fe of 0.95:0.05, of diameter 15±5 mcm, length of 6±3 mm and partial removal of glass shell from metal core of mark.
EFFECT: eliminating mark corrosion and achieving high and stable response signal, as well as improving mechanical properties of marks.
