The invention discloses a resin for a printing ink which comprises an ester-modified hydrocarbon resin, which is ester-modified with a long chain aliphatic alcohol, having a melting point of not lower than 100ºC, wherein the ester-modified hydrocarbon resin has not higher than 100ºC at a clouding temperature as the solubility in a hydrocarbon solvent having an aromatic component of not greater than 3% byweight, comprising a naphthene hydrocarbon and/or a paraffin hydrocarbon and having a boiling point of not lower than 200ºC.
The invention provides the excellent properties in the suitable emulsification property, the misting property, set and the drying property as a printing ink which is prepared using the hydrocarbon solvent.
