Abstract
A secure point of sale imageable substrate is disclosed comprising a heat sensitive recording material for recording confidential information. The heat sensitive recording material comprises a heat transmissive optically opaque paper support, a heat sensitive imaging layer coated on the paper support, a removable cover sheet, and a transparent layer or sheet positioned between the heat sensitive layer and the removeable cover sheet. A method for recording confidential information using such a secure point of sale imageable substrate is also disclosed.
Claims20
A heat sensitive recording material for recording confidential information comprising:
- (i) a heat transmissive, optically opaque paper support,
- (ii) a heat sensitive imaging layer coated on the paper support,
- (iii) a transparent sheet applied over the heat sensitive imaging layer,
- (iv) a removable cover sheet applied over the transparent sheet covering the heat sensitive imaging layer, wherein the heat sensitive imaging layer is able to be imaged through the opaque paper support, and read through the transparent sheet when the removable cover sheet is separated from the transparent sheet.
A heat sensitive recording material for recording confidential information comprising:
- (i) a heat transmissive optically opaque paper support,
- (ii) a heat sensitive imaging layer coated on the paper support,
- (iii) a removable cover sheet,
- (iv) a transparent layer positioned between the heat sensitive imaging layer and the removable cover sheet.
A heat sensitive recording material for recording confidential information comprising;
- i) a substantially optically opaque paper support,
- ii) a heat sensitive imaging layer,
- iii) a heat transmissive optically-transparent sheet applied over the heat sensitive imaging layer,
- iv) a heat transmissive, optically opaque removable cover sheet applied over the heat transmissive optically-transparent sheet covering the heat sensitive imaging layer, wherein the heat sensitive imaging layer is able to be imaged through the cover sheet and optically-transparent sheet, and read though the optically-transparent sheet when the cover sheet is separated from the optically-transparent sheet.
A heat sensitive recording material for recording confidential information comprising:
- (i) a transparent sheet having first and second surfaces and having coated on the first surface a heat sensitive imaging layer;
- (ii) a heat transmissive, optically opaque layer coated over the heat sensitive imaging layer;
- (iii) a removable cover sheet applied over the second surface of the transparent sheet, wherein the heat sensitive imaging layer coated on the first surface is able to be imaged by application of heat through the optically opaque layer, and read through the transparent sheet when the cover sheet is separated from the transparent sheet.
A method of recording confidential information comprising:
- (i) providing a substrate assembly, the substrate assembly comprising a heat transmissive optically opaque paper support, a heat sensitive layer over the paper support, a transparent sheet over the heat sensitive layer, and a removable cover sheet over the transparent sheet;
- (ii) imaging the substrate assembly through the opaque paper support with a reverse image by selectively applying a heat source to the opaque paper support, the image being viewable through the transparent sheet from a direction opposite to the direction of imaging through the opaque paper support.
A method of recording confidential information comprising;
- (i) providing a substrate assembly comprising a substantially optically opaque paper support, a heat sensitive layer over the paper support, a transparent sheet over the heat sensitive layer, and a removable cover sheet over the transparent sheet, the transparent sheet and removable cover sheet being heat transmissive, the removable cover sheet additionally being substantially optically opaque;
- and
- (ii) thermally imaging the heat sensitive layer of the substrate assembly through the cover sheet and transparent sheet.
