Abstract
Pressure-sensitive master sheets are produced by printing ink-releasing images onto a master sheet by silk screen techniques using a semi-solid printable ink composition comprising a wax and/or resin binder material, an incompatible oleaginous material, colorant and a volatile vehicle. The solidified printed images comprise a porous, spongy network of the binder material containing within the pores thereof the oleaginous material and colorant as a pressure-exudable ink. The printed master is suitable for the production of several copies in a dry pressure-copying process.
