摘要： The present invention provides a composition, which comprises an aqueous-based solvent and forms a transparent colourless coating, which yields markings of high contrast on exposure to energy. It also provides a process for the preparation of these compositions, substrates coated with these compositions and a process for their preparation, a process for preparing marked substrates using these compositions and marked substrates obtainable by the latter process.
