    摘要: A process for making printing plate material suitable for imaging by laser radiation. A metal substrate is electrocoated in a bath containing a polymeric resin and laser-sensitive particles, thereby depositing a laser ablatable layer on a principal surface of the metal substrate. In one embodiment, the laser-ablatable layer is treated with a corona discharge for a time sufficient to render the layer non-ink wettable. In other preferred embodiments, the laser-ablatable layer is overcoated with an overlayer such as a non-ink wettable silicone layer or a water-wettable layer comprising an organophosphorus polymer, preferably a copolymer of acrylic acid and vinylphosphonic acid.

    摘要: An aluminum-polymer composite is made by coating a surface portion of an aluminum alloy body with a primer composition comprising a vinylphosphonic acid-acrylic acid copolymer to form a primer layer, coating the primer layer with a radiation curable polymer precursor, and irradiating the polymer precursor with ultraviolet or electron beam radiation. The process of the invention is particularly suitable for making polymer coated aluminum alloy sheet that is shaped into container end panels for food and beverage containers.
