| Abstract(in English) | The effect of the under layer on surface smoothness of a simultaneously double coated MP tape was investigated. A smooth surface of the under layer could be obtained by highly dispersing particles in the under layer The pore volume of the under layer decreases with an increase in the degree of dispersion of the particles. The double-layer coatings showed approximately the same storage modulus, E' values over 100℃ independent of binder resins used, which suggests that they indicate the same viscoelastic behavior at calendering temperature. The surface of the double coated tape with the under layer having a good dispersion of particles was smoother than that of the single magnetic layer The improvement of electromagnetic characteristics was due to both the reduction of surface roughness and the thinner thickness of the magnetic layer. |
