Beschreibung
Zusammenfassung:	A linerless label system comprising pressure adhesive coating, release coati ng and thermal imaging coating is described. The thermal imaging coating contai ns as one of its components the compounds of the formula (I), wherein R1 and R2 are selected from methyl, ethyl, aryl, aryl substituted with methyl, ethyl, methoxy, ethoxy or halogen, benzyl or benzyl with phenyl substituted with methyl, ethyl, methoxy, ethoxy or halogen, R3, R4, R5 and R6 are selected fr om hydrogen, halogen, methyl, ethyl, methoxy, ethoxy, phenyl, R7 and R8 are eac h independently selected from methyl or ethyl, R9 is selected from hydrogen, methoxy or ethoxy, R10 is selected from hydrogen, dimethylamino or diethylamino, R11 is methyl. The imaged linerless label according to the invention has been a bar reflectance of less than 20 at 670 nanometers, a print control contrast signal of at least 80 and a BNL background of at leas t 75%.
