CONSTITUTION:A soln. prepd. by dissolving an organosilane compound represented by the formula (where R is H or 1-4C hydrocarbon, k is 4-16, l is 2- 18, and n is 0-2) in ''Freon'', toluene, hexane or the like is coated on the surface of a ferromagnetic metallic thin film, and the soln. is dried to form a layer of a surface treating agent contg. about 0.5-100mg/m organosilane. This layer has high adhesive strength to the magnetic film, so a recording medium having a low coefft. of friction, superior wear resistance, traveling performance and durability is obtd. Since the OR groups in organosilane are hardly hydrolyzed even at high humidity, the lubricity of the recording medium is not reduced.

摘要： PROBLEM TO BE SOLVED: To improve workability, form-preservation characteristics, and absorbance by forming an electromagnetic wave absorbing layer whose main components are soft-magnetic particles and a binder on a peelable support body, and bonding first main surfaces together. SOLUTION: An electromagnetic wave absorbing layer 2 is formed on a peelable support body 1, and the absorbing layer 2 comprises a first main (front) surface 21 and a second main (rear) surface 22. The bonding surface wherein a pair of structure bodies is bonded is set as first main surfaces of the electromagnetic wave absorbing layer 2. The peelable support bodies 1 on both surfaces of the structure body are all peeled, which is an electromagnetic wave support body comprising only a pair of electromagnetic wave absorbing layer 2. In order to raise an electromagnetic wave absorbing ability, only the peelable support body 1 on one side is peeled and exposed second main surfaces 22 are stacked, and then continuously allowed to pass a heating roller method laminator for heat/pressure bonding under the condition of 150 deg.C, 10 kg/cm2. Thus, thin, light weight, and flexible material is provided with excellent mechanism while excellent in workability and form-preserving characteristics and providing a high absorbing performance.
