PURPOSE:To enhance printing density and to prevent background staining and the delamination of an ink layer, by specifying the ratio of a resin and oil in an ink layer. CONSTITUTION:The title multistrike film ribbon is constituted so that the ratio of the resin for forming the sponge structure in an ink layer and oil being an ink component is set to 1.3-2:1. When the resin is below 1.3 times the oil, background staining is conspicuous and the ink layer is released from a substrate at the time of printing. If the resin exceeds two times of oil, the occupying ratio forming the sponge structure becomes too high and almost all of pores are lost and ink is not almost exuded even if printing pressure is applied to cause the lowering in printing density. This film ribbon can be formed by a conventional method. |
