摘要： The present invention relates to thermal recording materials comprising (in order):
- a support (base) layer;
- one or more "undercoat" layers;
- a thermal layer (thermosensitive coloring layer); and
- one or more "protective" layers,
wherein the thermal recording material contains an aminocarboxylic chelating agent according to formula (1) and may additionally contain a phosphorus-based chelating agent.
The thermal (thermosensitive) recording materials of the invention show enhanced plasticizer resistance and/or preprint uniformity.

摘要： The invention relates to a heat-sensitive recording material. A heat-sensitive recording material, comprising a carrier substrate and a heat-sensitive, colour-forming layer that contains at least one colour former and at least one phenol-free colour developer, is characterised in that said at least one colour developer is a compound of formula (I) where Ar
1 and Ar
2 are a phenyl group and/or a C
1 -C
4 -alkyl substituted phenyl group. The invention also relates to a method for producing this heat-sensitive recording material and to the use, in a heat-sensitive recording material, of the colour developer of formula (I) that is present in said heat-sensitive, colour-forming layer.

摘要： A linerless label system comprising pressure adhesive coating, release coating and thermal imaging coating is described. The thermal imaging coating contains as one of its components the compounds of the formula (I) wherein R 1 and R 2 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, R 3 ,R 4 ,R 5 and R 6 are selected from hydrogen, halogen, methyl, ethyl, methoxy, ethoxy, phenyl, R 7 and R 8 are each independently selected from methyl or ethyl, R 9 is selected from hydrogen, methoxy or ethoxy, R 10 is selected from hydrogen, dimethylamino or diethylamino, R 11 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 least 75%.
