Abstract: An attempt is made to develop a screen ink composition, based on lignin obtained from black liquor as a partial replacement for conventional alkyd resin. Lignin has been used as a replacement for alkyd resin to an extent of 35%. Unlike the conventional alkyd resin, efforts were made to prepare a novel alkyd resin with short oil length (20%) using chain stopper. The overall consumption of petroleum solvent in ink is around 16% which is much lesser than conventional ink which utilizes around 40% solvent. The physicochemical and film properties of ink have been studied and compared with commercial sample. The cost of the present product is less than the conventional product.
