摘要

A multiple-use pressure-sensitive transfer recording media which comprises a foundation and a finely porous layer provided on the foundation, said porous layer comprising minute porous particles and a binder material for bonding the porous particles to each other and containing a liquid ink paste substantially incompatible with the binder material, characterized by at least one of the following features: (i) that said liquid ink paste containes as a coloring agent a pigment, and an oil-soluble dye in a state that it is dissolved in a liquid fatty acid, and said liquid ink paste has a viscosity of not less than 300 cP and less than 4,000 cP at ordinary temperature; (ii) that said binder material is a vinyl chloride-vinyl acetate copolymer comprising 4 to 7 parts by weight of vinyl chloride and 5 parts by weight of vinyl acetate; and (iii) the combination of the foregoing features (i) and (ii). The recording media gives clear and sharp images without unevenness and spots for a multiplicity of strikes.
