PURPOSE:To prevent ground contamination or trailing from occurring under high-temperature environments, by a method wherein an ink layer softened or melted when being heated is provided on a base by coating, and a silicone oil layer is provided thereon by coating. CONSTITUTION:A heat-fusible ink layer is provided by applying a conventional composition to a base by a known method. A silicone oil is applied to the ink layer. The silicone oil is a synthetic oil having an inorganic siloxane structure (Si-O-Si) and an organic methyl or phenyl group, or one in which an organic group such as olefin or polyether group is introduced to a part of methyl group. Examples of this include dimethylsilicone oil, methylstyrene-modified silicone oil or the like. The silicone oil is applied in an amount of preferably 0.005-0.3g/m<2>, and it can be easily handled when being diluted with a solvent. Coating is conducted by a known method such as roll coating. |
