Abstract
A thermosensitive pressure sensitive label is provided which includes a substrate, a thermosensitive layer on one side of the substrate and a pressure sensitive adhesive layer disposed on an opposite side of the substrate. A barrier layer on top of the thermosensitive layer is covered with a silicone layer which enables the label to be rolled upon itself and unrolled without the use of a conventional backing sheet. In addition, the silicone layer enables color images formed in the thermosensitive layer to have a greater image density than the image density of color images that can be formed in the thermosensitive layer without the silicone layer being disposed thereover.
Claims12
A thermosensitive, pressure sensitive label comprising:
- a substrate;
- thermosensitive layer means for forming color images of measurable image density when a preselected portion thereof is heated by a thermal printing head, said thermosensitive layer means being disposed on one side of said substrate with a bottom surface thereof in contact with said substrate;
- a pressure sensitive adhesive layer disposed on an opposite side of said substrate;
- a barrier layer disposed on a top surface of the thermosensitive layer means;
- and
- silicone layer means, disposed on said barrier layer, for causing color images formed in said thermosensitive layer means, in response to heating by the thermal printing head, to have a greater image density than the image density of color images that can be formed in the thermosensitive layer means by the thermal printing head without the silicone layer means being disposed on said barrier layer, said silicone layer means being further operative for enabling the thermosensitive pressure sensitive label to be rolled with the pressure sensitive adhesive layer in contact with the silicone layer means and unrolled without significant adhesion to the silicone layer means, said silicone layer means comprising a moist air cured silicone system.

- silicone layer means, for causing color images formed in said thermosensitive layer means, in response to heating by the thermal printing head, to have a greater image density than the image density of color images that can be formed in the thermosensitive layer means by the thermal printing head without the silicone layer means being disposed on said barrier layer, said silicone layer means being further operative for enabling the thermosensitive pressure sensitive label to be rolled with the pressure sensitive adhesive layer in contact with the silicone layer means and unrolled without significant adhesion to the silicone layer means, said silicone layer means comprising a moist air cured silicone system;
- and
- barrier layer means, disposed between a top surface of the thermosensitive layer means and said silicone layer means, for preventing interaction between the thermosensitive layer means and the silicone layer means during application of the silicone layer means.
