  • Patent number: 6740465
    Abstract: Photothermally sensitive recording sheets for color imaging are disclosed comprising a transparent support sheet having a thermal slip layer disposed on one surface of the support and a heat sensitive image layer on the opposite surface of the support. A second opaque (paper) or transparent (plastic) sheet is laminated to the color-producing layer. The image layer comprises photohardenable microcapsules containing a photopolymerizable or photocrosslinkable compound, a photoinitiator and a dye precursor and a developer material external to the microcapsules. Image-wise exposure of the recording sheet to actinic radiation causes selective photohardening of microcapsules sensitive to that radiation. Heating the resultant exposed recording sheet to a temperature well above the developer melting point by for example a thermal head allows the developer to selectively permeate the non-photohardened capsules resulting in the development of an image, including full color images.

    Abstract: The present invention provides a method of registering to an imaging web moving within an imaging web handling apparatus along an imaging web path. The imaging web comprises a support having a coating of photosensitive microcapsules on the surface thereof. The photosensitive microcapsules have an internal phase of a photosensitive composition and a color former. Exposure of the imaging web to actinic radiation defines an image area and a border area.A registration mark is formed on the web by exposing a portion of the web area to actinic radiation so that the portion undergoes a color or reflection change, or exposing all but a portion of the border area to actinic radiation so that the exposed area undergoes a color or reflection change. The registration mark is detected and in response to detection of the registration mark, an operation is performed on the imaging web.
