Radiation polymerizable coating composition containing an unsaturated phosphoric ester
Abstract
Abstract A radiation polymerizable protective coating composition or paint, coated articles bearing such a protective coating and processes for preparing such articles. The radiation polymerizable paint, on a non-polymerizable solvent, pigment, initiator and particulate filler-free basis consists essentially of a binder solution of: (1) an alpha-beta olefinically unsaturated organic resin containing between about 0.5 and about 5 units of olefinic unsaturation per 1,000 units of molecular weight; (2) a compound polymerizable with said resin upon exposure to ionizing radiation; and (3) between about 0.05 and about 1.0 parts per 100 parts of the total of said alpha-beta olefinically unsaturated resin and said compound polymerizable therewith of a mono-or diester of phosphoric acid bearing one or more sites of vinyl unsaturation. The composition exhibits excellent quality and good adhesion to a variety of substrates, in particular metals, including vapor deposited metals. Preferred articles bearing such a coating are prepared by: applying a base coat to a substrate and curing the same; vapor depositing a coating of a metal over the surface of the base coat; and applying to and curing on the surface of the deposited metal the radiation polymerizable topcoat, preferably with little or no pigment contained therein.
