PURPOSE:To improve flaw resistance, reflection-preventing properties and processing resistance of a coated article and perform dirt retention-preventing treatment having high durability on the surface of the coated article by applying a coating composition mainly comprising polysiloxane having a specified siloxane unit in a predetermined thickness onto a plastic base material. CONSTITUTION:A plastic base material is coated with a coating composition mainly comprising polysiloxane having a siloxane unit as represented by a chemical formula 1 wherein X is a substance represented by chemical formulas 2, 3. R1 in formulas 1, 2, 3 is selected from among H, CH3 and F, a is an integer of 2 to 4, b is an integer of 3 to 14 and c is 1 or 0. d=2-c. R2 is selected from among a methyl group, an ethyl group, a fluoroalkyl group and X. Coating is made in a thickness of 1nm or more and 20nm or less. |
