Abstract: This invention pertains to a donor element for use with a receiver element in an imagable assemblage for light-induced transfer of material from the donor element to the receiver element. Specifically, this invention relates to such a donor element comprising a copolymer based on styrene and maleic anhydride.

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.

Abstract: A donor element useful in an assemblage for imaging by exposure to radiation comprises a substrate, a transfer-assist layer disposed adjacent the substrate comprising one or more water-soluble or water-dispersible radiation-absorbing compound(s), and a transfer layer disposed adjacent the transfer-assist layer opposite the substrate.

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.

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.

Abstract: Uniform, microscopic perforated water soluble film is herein described, and its use in packaging solid, pelletized or particulate detersire compositions containing strong acids, strong bases or a source of halogen whereby the package provides air to pass through without leakage of its contents. Also described is a method of manufacture of a sealed, water soluble, detersire package with microscopic perforations and an apparatus for said manufacture.
