摘要：
The magnetic material which is coated on the back of cine sound film is prevented from dissolving together with the antihalation layer. The magnetic layer is easily eliminated by alkali developing treatment. A typical magnetic dispersion consists of nitrocellulose 10, Fe oxide 30, di-Bu phthalate 2, MeCO2Et 20, MeCO2Bu 30, acetyl cellosolve 20, and I 0.5 parts by wt. %.
