Abstract
In this work, surface treatment of metal particles was performed by kneading with various solvent. The metal particles obtained from the surface treatment were kneaded, diluted and dispersed to make paint, and it was used to form paint films. The dispersion state and magnetic properties of metal particles were studied.
Considering the results of SEM observation, glossiness and measurement by STM and XMA, the state of dispersion was clarified. It was found that surface treatment of metal particles obtained well-dispersed state of the particles, and magnetic tape with high magnetic property (magnetic retentivity) was formed. From the results, it was indicated that surface treatment of metal particles is effective on production of highgrade videotape.
