Abstract

The invention relates to a marking composition, by means of which better protection of goods than hitherto available can be achieved independently of the coloring of the goods. The marking composition comprises an infrared-absorbing particulate component and carbon derivative, wherein the weight ratio of infrared-absorbing component to carbon derivative is in the range of approx. 10:1 to approx. 10,000:1.
