Abstract
Abstract A multiple-use pressure-sensitive transfer recording media which comprises a foundation and a finely porous resinous layer provided on the foundation, said porous layer comprising minute porous particles and a resinous binder material for bonding the porous particles to each other and containing a liquid ink paste substantially incompatible with the resinous binder material, said liquid ink paste comprising a pigment, a liquid fatty acid and an oil-soluble dye dissolved in said liquid fatty acid, and the weight ratio of said fatty acid to said dye being from 20:1 to 2:1. The recording media gives clear and sharp images without unevenness and blur for a multiplicity of strikes.
