Release Enhancing Layer Patents (Class 428/32.81)
  • Patent number: 7670450
    Abstract: A thermal transfer donor element is provided which can include a support, light-to-heat conversion layer, interlayer, and transfer layer. When the donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. In order to enhance the lifetimes of the transferred material, thermal treatments such as annealing are applied to the receptor before transfer, to the transfer layer after transfer, or a combination of them. The construction and process of the donor element is useful in making colored images including applications such as color proofs, color filter elements, and organic light emitting diode displays and devices.

    Abstract: Methods and products for forming a coated image on a substrate are generally disclosed. The methods can include forming an image on a printable surface of a transfer coating layer of a printable transfer sheet. In a separate step, the negative mirror image of that same image is printed with toners on a toner printable sheet. After registering the sheets together, a portion of the transfer coating layer of the printable transfer sheet is transferred to the toner printable sheet, such that the portion of the transfer coating layer transferred to the toner printable sheet corresponds to the imaged areas on the toner printable sheet. However, the image formed on the printable surface of the transfer coating layer and the underlying transfer coating substantially remain on the printable transfer sheet. Thereafter, the image and the transfer coating layer remaining on the printable transfer sheet are transferred to a substrate.

Thermosetting light-emitting materials are used to form the red, green, and blue light-emitting layers, and a laser is then selectively irradiated onto a light-to-heat conversion layer formed on the substrate to deliver heat energy converted from light energy through the light-to-heat conversion layer to the thermosetting light-emitting materials so that curing is progressed to form patterned light-emitting layers. In accordance with the fabrication method of the present invention, the light-emitting materials may be patterned using a laser, thereby fabricating a large scaled organic electroluminescence display device and simplifying the process by not using a mask when the light-emitting layers are formed.

    Abstract: A roll stock of a graphic transfer strip for use in making a high visibility safety garment for wearing by an individual exposed to a higher than normal risk of injury from vehicular traffic. The safety garment complies with the visibility requirements of a published standard such as the American National Standards Institute for High Visibility Safety Apparel. The safety garment has one or more high visibility safety stripes that encircle the torso. The safety stripe is formed of a plurality of separate but closely spaced stripe segments in a generally repetitive pattern that is substantially continuous for the length of the stripe. The stripe segments are formed of a retroreflective material. The stripe segments occupy a portion of the total area of the stripe sufficient to impart to the stripe a coefficient of retroreflectivity that meets or exceeds that required by the standard being addressed for the safety garment.
