Abstract
The present invention provides polymeric particles comprising a polymeric matrix comprising one or more water-insoluble polymers and a laser-sensitive system encapsulated in the polymeric matrix. It also provides a process for the preparation of the polymeric particles, a composition comprising the polymeric particles, a process for the preparation of this composition, a process for forming a laser-sensitive coating layer on a substrate using this composition, a coated substrate obtainable by the coating process, a process for preparing a marked substrate and a marked substrate obtainable by the marking process.
