METHOD FOR PRODUCING A FILM HAVING LUMINESCENT PARTICLES

摘要

A method for producing a film having luminescent particles is described. The method has steps a) mixing a thermoplastic and a luminescent pigment containing a hydroxyalkyl terephthalate of the formulate: R1—COO—P(OH)x-COO—R2 and obtaining a thermoplastic mixture; and b) homogenizing the thermoplastic mixture to 150° C. to 200° C. in an extruder, by way of an extrusion nozzle, and obtaining a thermoplastic film.

1. A method for producing a film having luminescent particles, comprising:
a. mixing a thermoplastic and a luminescent pigment containing a hydroxyalkyl terephthalate of the formula R1—COO—P(OH)x-COO—R2, thereby obtaining a thermoplastic mixture,
wherein R1, R2 is an alkyl, aryl, or allyl radical having 1 C to 10 C atoms, P is a phenyl ring, OH is a hydroxyl group bound to the phenyl ring, and x is an integer from 1 to 4, and b. homogenizing the thermoplastic mixture in an extruder at 150° C. to 200° C., and obtaining a thermoplastic film via an extrusion nozzle of the extruder.
