Linerless direct thermal label |
摘要 |
A linerless thermal label is produced by disposing a thermosensitive layer into a substrate and allowing the thermosensitive layer to dry, said thermosensitive layer comprising a color former causing the thermosensitive layer to remain color stable. A protective layer is applied on top of the thermosensitive layer and exposes the protective layer to a temperature and a time sufficient to dry the protective layer but not cause the thermosensitive layer to a change color. A heat curable silicone mixture is disposed on said protective layer and thereafter cured to form a release layer without causing color change in the thermosensitive layer. A pressure-sensitive adhesive is applied on an opposite side of the substrate which is exposed to a temperature for a time sufficient to dry the pressure-sensitive adhesive without causing color change in the thermosensitive layer, and the substrate is then rolled in a manner causing the pressure-sensitive adhesive to contact the release layer.
