MAGNETISCH REGISTRATIEMEDIUM VAN POLYESTER MET EEN TUSSENLAAG VAN EPOXYHARS. |
| 摘要 |
<p>Cationically polymerized epoxy resin subbing layer for the magnetizable and the backside coating, if any, of polyester-film-backed magnetic recording tape acts as a barrier against extraction and migration of low-molecular-weight components of the polyester film backing which otherwise would tend to crystallize on the surface of the magnetizable coating.</p> |
