Magnetic recording medium and recovery method thereof |
| abstract |
(57) [Summary] [Purpose] A magnetic recording medium suitable for environmental protection, which has a high adhesion and is provided with an undercoat layer which is easily peeled off with a weak alkaline or low-concentration alkaline aqueous solution at the time of disposal, and a recovery treatment method therefor. provide. A magnetic recording medium comprising an undercoat layer between a non-magnetic plastic support and at least a magnetic layer and / or a back layer, wherein the porosity of the magnetic layer and / or the back layer is at most 40% by volume. Yes, the undercoat layer is 40 ° C Is more soluble in a 0.5% by weight aqueous alkaline solution at 40 ° C. than in water, and at the highest, is easily soluble in a weak alkaline solution having an initial pH of less than 13 or a low-concentration alkaline aqueous solution. Magnetic recording medium and its recovery processing method. |
