ないことになってしまう。In recent years, there has been a demand for reducing the amount of these solvents and increasing the safety from the viewpoints of consideration for the health of ink handlers and the safety of printed matter due to the solvent components of the remaining ink. As a method of reducing these solvents and improving the safety, there is a method of increasing the content of animal and vegetable oils and fats such as linseed oil, which is a vehicle component of the ink, and reducing the usage ratio of the solvent. However, when the animal or vegetable fat component in the ink is increased, the viscosity of the ink is significantly increased. Therefore, inks with an increased ratio of animal and vegetable fats and oils have less fluidity than conventional inks and are poor in usability. In particular, for inks that require osmotic drying, if the viscosity of the vehicle is high, the osmotic speed is low, and the drying property is poor. In order to solve these problems with the conventional technology, a solvent which has been used conventionally, such as a petroleum system, has to be used to some extent.

る。The ester of the present invention sufficiently dissolves rosin, a phenol resin, a petroleum resin, and the like, which are resin components of the ink. The viscosity of the ink and the boiling point of the solvent can be controlled by changing the alkyl group composition of the ester. Therefore, it is possible to sufficiently replace the conventional petroleum-based high boiling point solvent. The ester of the present invention has the advantage that the ester bond is easily decomposed in the ecosystem, and the fatty acids and alcohols, which are decomposed products, are highly safe from their origin. As described above, an ink using the ink solvent of the present invention is used as a lithographic ink, such as a newspaper ink or the like, or a relief ink, which is required to have a high drying point and is required to have a good drying property. It is possible.

優位性がある。As shown in the examples, the vehicle using the ester of the present invention as a solvent is the same as the vehicle using a high-boiling petroleum solvent, except that the resin which is a film-forming substance of the ink and the drying oil ( Linseed oil) with an appropriate viscosity, and an ink using this vehicle has almost the same performance as a conventional product. Since the ester of the present invention uses fatty acids present as animal and vegetable oils and fats,
Higher safety than petroleum solvents. In addition, animal and vegetable fats and oils are reproducible resources, and from this point of view, the present invention has an industrial advantage.
