A method for producing oil-based printing extender pigment dispersions, oil-based printing extender pigment dispersion obtained by the production method and use thereof

摘要

Even while using the extender pigments that do not wet, increase the dispersibility in the wettable with a wetting agent comprising water in water alone, the oil-based printing extender pigment dispersion to significantly increase productivity than conventional means the oily printing extender pigment dispersion obtainable production process, in the manufacturing method, and uses thereof. The mass of the (A) / (B) = 99.9 / 0.1~80.0 / 20.0 Water (A), a specific compound and (B), and 100 parts by weight of extender pigment is surface treated oily printing extender pigments and a step is dispersed into the oil varnish in the steps of wetting with 19-190 parts by weight of wetting agent contained in the ratio, the extender pigment moistened, and then to effect removal of water (A) production method of the dispersion.
