Abstract
Abstract A method of coating comprising the steps of applying a photosensitive catalyst or a mixture of a combination of said catalyst and a photosensitizer or a combination of said catalyst, said photosensitizer and polymeric materials on a substance to be coated, irradiating actinic light rays upon said substance while said substance being contacted with a vaporized ethylenically unsaturated compound or compounds, and thereby forming a polymer film of said ethylenically unsaturated compound or compounds.
