Definitions

  • the amount of the cross-linkable monomer used is the total amount of monomers other than the cross-linkable monomer (non-cross-linkable monomer).
  • they are 0.05 mass part or more and 5.0 mass parts or less with respect to 100 mass parts, More preferably, they are 0.1 mass part or more and 5.0 mass parts or less, More preferably, they are 0.2 mass part or more. 4.0 parts by mass or less, and more preferably 0.3 parts by mass or more and 3.0 parts by mass or less. If the usage-amount of a crosslinkable monomer is 0.05 mass part or more, it is preferable at the point from which the binding property and stability of mixture layer slurry become more favorable.
  • the content of the medium containing water in the entire composition is determined from the viewpoints of slurry coating properties, energy costs required for drying, and productivity. From, for example, it can be in the range of 25-90% by mass, and can be, for example, 35-70% by mass.
  • the content of the medium can be set in the range of 3 to 40% by mass, for example, from the viewpoint of the uniformity of the mixture layer after pressing. It can be in the range of ⁇ 30% by mass.
