Appl. No.:

09/745700

Michael J. Arnost - North Andover MA
Alain Bouchard - Boston MA
Yongqi Deng - Newton MA
Edward J. Dombrowski - Bellingham MA

Assignee:

Polaroid Corporation - Waltham MA

International Classification:

B41M 530

US Classification:

156235, 106 3129, 428195

Abstract:

There is described a thermal recording system which utilizes a donor element comprising a substrate and a thermal transfer material layer having a dye-containing phase which is amorphous and wherein the dye or dyes present in the amorphous phase form a continuous film. Imagewise heating of the medium transfers portions of the transfer layer to a receiver sheet, thus forming an image. The transfer layer may also include a non-dye phase comprising a thermal solvent. During the heating of the donor element, the crystalline thermal solvent melts and dissolves or liquefies at least a portion of the dye-containing phase, thereby lowering the temperature at which transfer of the transfer layer occurs.

US Classification:

156235, 428 3239, 428 325

Abstract:

There is described a nanoporous receiver element for use in thermal mass transfer imaging applications. The receiver element comprises a substrate carrying an image-receiving layer comprising particulate material and a binder material. The substrate may comprise a material having a compressibility of at least 1% under a pressure of 1 Newton per mm (1 MPa). Optionally, there may be provided, between the substrate and the nanoporous receiving layer, a layer having a thickness of less than about 50 m which is comprised entirely of a material having a compressibility of less than about 1% under a pressure of 1 MPa. Alternatively, the substrate may comprise only the material having a compressibility of less than about 1% under a pressure of 1 MPa, provided that the thickness of the substrate does not exceed about 50 m. The image-receiving layer comprises particulate material and a binder material, has a void volume of from about 40% to about 70% and a pore diameter distribution wherein at least 50% of the pores having a diameter greater than about 30 nm have diameters less than about 300 nm and at least 95% of the pores having diameters greater than about 300 nm have diameters less than about 1000 nm.

US Classification:

347188

Abstract:

A thermal printer is disclosed which includes a plurality of thermal print heads, each of the plurality of thermal print heads being operable to print a distinct one of a plurality of colors. The plurality of thermal print heads may print output at a plurality of spatial resolutions. The thermal printer may include dot size varying means for varying perceived levels of color printed by the thermal printer by varying sizes of dots printed by the plurality of thermal print heads. The printer may perform various image processing steps on an image to be printed, such as tone scale adjustment, thermal history control, and common mode voltage correction, to improve the perceived quality of the printed image. The thermal printer may be incorporated into a digital photo-printing vending machine for printing images provided by a customer.

US Classification:

257 43

Abstract:

The present disclosure provides for electronic devices that use low cost, conductive materials as transparent conductors. The devices contain corrosion preventative conductive polymer layers and conductive innerlayer barriers that separate corrosive electrolyte from the conductors which are prone to corrosion and dissolution, while providing an uninterrupted electrical circuit. The present disclosure also allows for the use of layers which have been applied from aqueous media thereby reducing both the cost and the environmental impact of the electronic devices. Methods of manufacture are also provided.
