| titleOfInvention | Magnetic recording medium and method for manufacturing binder for magnetic recording medium |
| abstract | A poor solvent is used for removing low molecular weight components from a binder, which has weight average molecular weight within the range of 10,000 to 60,000, said poor solvent has a solubility parameter being different from solubility parameter of the binder by more than 1.3 and less than 2.3 and is a solvent such as acetonitrile having no active hydrogen, and a difference between solubility parameter of the solvent in the solution after mixing and solubility parameter of the binder is more than 1.0 and less than 2.0, said poor solvent is used for fractional precipitation, and the poor solvent being by 0.5 to 3 times as much as the quantity of the binder solution is added to separate the solution to a liquid phase where low molecular weight components are dissolved more and a liquid layer where high molecular weight components are dissolved more and the latter is taken up, or an ultrafiltration membrane is used to remove low molecular weight components, content of the low molecular weight components having molecular weight of not more than 5,000 are reduced to not more than 3 weight % of total weight of the binder, and said binder is used for formation of a magnetic layer and a lower coating layer of a magnetic recording medium. |
