PURPOSE:To prevent generation of a malodorous gas during processing and improve an electric discharge drilling properties and a resistance to ink solvent to obtain a superior mimeographing properties, by a method wherein a resin containing a polymer of propylene series as a main ingredient, a conductive carbon black, a mineral oil or vegetable oil, and an organic silane compound are composed in a specific ratio. CONSTITUTION:A film is made of a composition of 50-82wt% of a resin containing a polymer of propylene series as a main ingredient, 30-15wt% of a conductive carbon black, 20-3wt% of a mineral oil or vegetable oil, and 0.05-3pts.wt. of an organic silane compound in relation to 100pts.wt. of the total quantities of the above contents. The film can prevent generation of a malodorous gas during processing because the resin containing the polymer of propylene series is used, and is improved in an electric discharge drilling properties, especially during a high-speed processing, because of the mineral or vegetable oil compounded therein as well as in a resistance to ink solvent, thus having no possibility of being stretched and wrinkling in mimeographing and preventing an unclear printing. Additionally, the film has a uniform thickness because the organic silane compound is compounded therein, thus obtaining a uniform electric discharge drilling properties with a uniform thickness. |
