    摘要: An image-forming medium and methods for forming and imaging the medium are provided. The disclosed medium can be strongly colored under room illumination (or deliberate UV) and can be selectively discolored at an appropriate light wavelength to form an image. In one embodiment, the image-forming medium can include a substrate (e.g., a sheet of paper), a photochromic material incorporated with the substrate, and a photo-absorbing material incorporated with the photochromic material. Exemplary methods for using the image-forming medium to make a transient image can include first forming the image-forming medium by applying a coating solution containing photochromic material to the substrate or paper. The image-forming medium can have a medium color and can then be selectively exposed to a radiation through a mask to convert the photochromic material from a colored form to a colorless form and thus to form an image having a color contrast with its background.

    摘要: Provides is a method for forming tactile images or a combination of tactile and regular images on a flexible packaging substrate comprising:
    depositing an ultraviolet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; and a gellant directly onto a flexible packaging substrate or depositing the ink onto an intermediate transfer member, in an image area to form a tactile image area or a combination of tactile image area and regular image;
    forming the tactile image by depositing multiple layers of the ink in locations of the tactile image area or portion thereof;
    when an intermediate transfer member is used, transferring the deposited ink from the intermediate transfer member to the flexible packaging substrate; and
    curing the ink.
