PURPOSE:To obtain a discharge type recording mimeographic film excellent in ink-solvent resistance and printing durability as well as having good discharge drilling performance, which gives off no offensive odor gases, by using a film of a specific olefinic polymer to be cross-linked with silanes, having a specific gel fraction. CONSTITUTION:A film, consisting of 90-70wt% a resin component composed of 1-50wt% olefinic polymer containing 0.5-10wt% a vinyl silane compound (e.g., modified olefinic resins grafted with vinyl silane compound or alpha-olefin-vinyl silane compound random copolymer) and 99-50wt% at least one selected from ethylenic copolymers and crystalline propylene polymers and 10-30wt% conductive carbon black, is dipped in water to bring about cross-linking with silane. The film is then bonded to a conductive base paper with the aid of a binder to form a discharge type recording mimeographic film. The preferred gel fraction of the silane-cross linking is 0.5-40%, more preferably 1-35%. |
