  • Donor element with release-modifier for thermal transfer
    Patent number: 7763411
    Abstract: A donor element useful in an assemblage for imaging by exposure to light comprises a support layer, a light-to-heat conversion layer disposed adjacent the support layer containing a light absorber, and a transfer layer disposed adjacent the light-to-heat conversion layer opposite the support layer. The donor element also includes a release-modifier disposed between the support layer and the transfer layer.

  • Donor element for thermal transfer
    Patent number: 7387864
    Abstract: A donor element useful in an assemblage for imaging by exposure to light comprises a support layer formed by a stretching process, a light-to-heat conversion layer disposed adjacent the support layer containing a light absorber, and a transfer layer disposed adjacent the light-to-heat conversion layer opposite the support layer. The light-to-heat conversion layer is coated on the support prior to completion of the stretching process.

  • Primed polymer films having improved adhesion characteristics and processes for making the films
    Patent number: 6114021
    Abstract: This invention covers a film base wherein polymers forming a polymeric film surface and selected from polyesters, polyolefins and polyamides are coated with an adhesion enhancing primer coating containing (a) a functionalized .alpha.-olefin containing copolymer; and (b) a crosslinking agent selected from the group consisting of amino formaldehyde resins, polyvalent metal salts, isocyanates, blocked isocyanates, epoxy resins and polyfunctional aziridines; and wherein the adhesion enhancing primer coating is applied to the polymeric film surface and reacted, at elevated temperatures with newly generated polymeric film surfaces formed during uniaxial or biaxial stretching and heat setting.
