This invention relates to an ink-setting layer composition for a substrate to make it suitable for offset printing or letterpress printing where an oil ink of the oxidative polymerization type is used. An ink-setting layer composed principally of a rubbery resin and/or styrene resin is provided on the substrate, where the substrate permits lithographic offset printing or the like. Fine ruggedness may be formed on the substrate. The substrate antistatic treatment. Sheet-fed printing making use of the above film does not develop blocking, tacking, scratches, abrasion, etc. The above-described various properties have been improved further in a substrate provided with an ink-setting layer, which has been formed by coating a mixture of (i) a solution of the rubbery resin and/or styrene resin and (ii) a silica sol. A method for applying the composition is also included.
