A process for coating articles which comprises the steps of causing a reaction between a methacrylic acid ester having hydroxyl groups and an isocyanate compound having at least two isocyanate groups in its molecule to obtain a partially urethanated compound, causing a reaction between said partially urethanated compound and a polyester having a hydroxyl group to produce an unsaturated polyester composition, applying said unsaturated polyester composition to articles to be coated, and irradiating ionizing radiation on the films of said unsaturated polyester composition formed on said articles, thereby obtaining hard but not brittle coatings on said articles.
