    摘要: The invention provides a novel means for solving and overcoming the problems in the magnetic recording tapes caused by the accumulation of static electricity during travelling of the tape affecting the quality of the reproduced sounds and picture images by playing the tape. The inventive method comprises providing at least one surface of the plastic-made film base with a layer of a plasma-polymerized gaseous compound of a specific type by exposing the surface of the film base to the atmosphere of low temperature plasma generated in the low pressure atmosphere of the gas or vapor of a compound such as an amine, organosilane, aliphatically unsaturated compound and aromatic compound, preferably, before coating the film base with a magnetic coating composition. The plasma-polymerized layer is effective to decrease the surface resistivity of the film base and to reduce the accumulation of static electricity induced by rubbing.

    摘要: The invention provides a novel method for modifying the surface properties, e.g. antistatic performance and anti-wearing resistance, of a disc-like shaped article made of a vinyl chloride-based resin such as a gramophone record by treating with low temperature plasma so as that the surface of the record is rendered antistatic and the noise generation in playing of the record is remarkably decreased. Different from conventional methods, a great uniformity of the effect by the plasma treatment is ensured by the inventive method all over the surface of the record since the record is transferred through the space between two parallel arrays of electrodes, preferably, with rotation around its axis during the plasma treatment. The manner of connecting the electrodes to the terminals of the high frequency generator may be in two different ways. For example, all of the electrodes in one array are connected to the grounded terminal while all of the electrodes in the other array are connected to the power-input terminal. Alternatively, each of the electrodes is connected to a terminal different from that to which both of the neighboring electrodes in the same array and the electrode in the other array oppositely facing it are connected. The record after the plasma treatment is preferably coated with a surface active agent and dried to enhance the effectiveness.

    摘要: A novel method is proposed for improving the surface properties or, in particular, for increasing the affinity to water of the surface of a shaped article made of a silicone, e.g. a silicone rubber. The inventive method comprises first exposing the surface of the shaped article of the silicone to low temperature plasma of an inorganic gas and then bringing the plasma-treated surface into contact with a liquid inert to the silicone which is an aqueous solution containing a surface active agent. The treated surface retains sufficient affinity to water even 6 months after the treatment.

    摘要: The invention provides a very efficient method for the improvement of the antistatic performance, e.g. decrease in the accumulation of static electricity on the surface and decrease in the surface resistivity, of a synthetic resin shaped article with outstanding durability of the effect. The method comprises two steps in principle, first of which is the formation of a crosslinked layer in the surface portion of the shaped article by a variety of known methods effective for the formation of crosslinks in polymeric materials and the second of which is the exposure of the thus crosslinked surface of the article to low temperature plasma produced in an atmosphere containing a gaseous silicon-containing compound which may be a silane compound or a low-molecular weight vaporizable siloxane compound to form a plasma-polymerized surface film of the silicon compound on the crosslinked layer.
