| titleOfInvention | Composition for working layer of magnetic record carrier |
| abstract | This invention relates to magnetic recording media, namely magnetic tape for video recording. The invention allows to improve the electromagnetic properties, reduce the specific surface electrical resistance and the dynamic friction coefficient of the magnetic carrier due to the additional use of polyvinylformal ethyl (1.6-2.4 wt.%) In the composition, wt.%: Magnetic chromium dioxide 24-36n n n dialkyl polyglycol ether orthophosphoric acid 0,8-1,2n n n polyetherurethane (with a hydroxyl number of 4-10) 3.2-4.8n n n the adduct of 2,4-toluene diisocyanate with trimethylolpropane 0.4-1.4n n n stearic acid amide 0.4-1.4n n n cyclohexanone 12.8-19.2 and tetrahydrofuran else. 1 tab. |
