<p>PURPOSE:To obtain the title ink having good scumming resistance and freed from hicky, picking and web break by mixing a high-MW rosin-modified phenolic resin with a normal paraffin and an alpha-olefin solvent. CONSTITUTION:A dry lithographic rotary press ink is produced by mixing a rosin-modified phenolic resin of a weight-average MW >=110000 (e.g. a resin obtained by reacting a resol phenolic resin with a rosin and a polyalcohol) with a normal paraffin desirably of a b.p. >=200 deg.C, and an alpha-olefin solvent. This ink is excellent in scumming resistance, and free from hicky. picking and web break, so that it is desirably used for lithographic rotary press.</p> |
