Intaglio printing inks using linseed fatty acid as the autoxidisable polyester resin

摘要

An Intaglio printing ink in which the binder is an autoxidisable polyester resin with fatty acid content between 40 and 60% by weight and the preferred fatty acid is linseed fatty acid. The fatty acid has at least 25% of its chain as linolenic acid. The printing ink includes solvents and pigments and can be cured under UV irradiation to produce useful printed material on polymer substrate.
