PARTICLES OF MELAMINE-UREA-FORMALDEHYDE (MUF) CONTAINING A POLYMER WITH A TG LESS THAN 75 °C.

摘要

The invention relates to a particle possessing a core formed entirely or partially from at least one polymer having a glass transition temperature less than 75 °C, encapsulated in a shell formed from at least one polymer of melamine-urea-formaldehyde. The invention further relates to the implementation of such particles to convey a marker material. Finally, the invention relates to the application of the particles thus loaded, in particular for the purposes of traceability and/or authentication of a support incorporating same.
