Abstract
The present invention provides a laser-sensitive coating composition comprising titanium dioxide in the anatase form or polymeric particles comprising a polymeric matrix comprising one or more water-insoluble polymers and titanium dioxide in the anatase form encapsulated in the polymeric matrix, and a polymeric binder. The present invention also provides a process for the preparation of the compositions, processes for preparing substrates coated with the coating compositions, substrates coated with the compositions, processes for marking the substrates coated with the compositions, and marked substrates obtainable by the latter processes.
