摘要： The surface of a positive-electrode active material layer or a negative-electrode an active material layer is coated with a gel electrolyte composition to form a gel electrolyte layer. The positive and negative electrodes are laminated such that the gel electrolyte layer is sandwiched. At this time, the gel electrolyte composition is formed into a sol form so as to be applied to the surface of the positive-electrode active material layer or the negative-electrode active material layer. The viscosity of the gel electrolyte composition formed into the sol form is 1 cp to 50 cp. The gel electrolyte composition is formed into the sol form by heating the gel electrolyte composition or diluting the gel electrolyte composition with nonaqueous solvent. When dilution with the nonaqueous solvent is performed, solvent having a high boiling point and solvent having a low boiling point are mixed with each other. After a coating operation has been completed, the solvent having the low boiling point is removed by vaporization. It is effective to heat the positive electrode or the negative electrode when the gel electrolyte composition formed into the sol is applied. Since the gel electrolyte composition formed into the sol form is applied, the electrolytic solution is able to quickly penetrate the active material layer.
摘要翻译：用凝胶电解质组合物涂布正极活性物质层或负极活性物质层的表面，形成凝胶电解质层。层叠正极和负极，使得凝胶电解质层被夹持。此时，将凝胶电解质组合物形成为溶胶形式，以施加到正极活性物质层或负极活性物质层的表面。形成溶胶形式的凝胶电解质组合物的粘度为1cp至50cp。凝胶电解质组合物通过加热凝胶电解质组合物或用非水溶剂稀释凝胶电解质组合物而形成溶胶形式。当用非水溶剂稀释时，具有高沸点溶剂和低沸点溶剂彼此混合。涂布操作完成后，通过蒸发除去低沸点溶剂。当施加形成为溶胶的凝胶电解质组合物时，加热正极或负极是有效的。由于形成为溶胶形式的凝胶电解质组合物，所以电解液能够快速地穿透活性物质层。

摘要： Disclosed is a magnetic recording medium having a first magnetic layer 2 and a second magnetic layer 4 laminated on a non-magnetic support in this order, wherein the binder in the lower first magnetic layer 2 comprises only polyurethane resin(s) having tertiary amines as polar groups or only said polyurethane resin(s) and a curing agent or comprises a mixed system composed of polyurethane resin(s) having tertiary amines as polar groups and amine-modified vinyl chloride-based resin(s) or of these resins and a curing agent. The first magnetic layer 2 may contain carbon black having a specifically-defined mean particle size. The coatability of the magnetic coating compositions is improved. The electromagnetic conversion characteristics (especially, video S/N, chroma output power, chroma S/N) of the medium are improved. Since the crosslinking of the components constituting the lower magnetic layer is improved, the dropout of the medium is not increased even after stored. This invention provides a magnetic recording medium capable of being subjected to long-sustained, high-quality recording and reproduction in severe conditions. The medium has high electric resistance, high light transmittance and good running durability, even though not having a back coat layer.
