2. Description of the Related Art Green sheets used in the production of multilayer ceramic substrates, multilayer ceramic capacitors and the like are generally made of a plastic film (eg, polyester film, polyimide film, polymethylpentene film, etc.) alone or A ceramic slurry is applied at an appropriate thickness onto a release film in which one side of these films is coated with a release agent such as silicone, and the slurry is dried by heating to produce a ceramic slurry.

[0003] The ceramic slurry is composed of ceramic powder, a plasticizer, a binder, and the like, and many combinations are possible. However, the slurry is roughly classified into an organic solvent type and an aqueous type depending on the type of the binder and its dissolving performance.

In this case, the organic solvent-based slurry uses, for example, polyvinyl butyral or ethyl cellulose as a binder and uses a solvent such as toluene or ethanol. This organic solvent-based slurry makes it possible to obtain a thin and tough green sheet due to the viscosity characteristics of the slurry and the like, but has problems in safety and workability, and also has problems in terms of environmental hygiene.

On the other hand, an aqueous slurry generally uses polyvinyl alcohol and an acrylic resin as a binder, and uses polyethylene glycol as a plasticizer. Although this aqueous slurry has no problem in terms of safety and the like, it is inferior in coatability and quality, and thus has a drawback that it is difficult to obtain a high-quality ceramic green sheet as compared with a solvent-based slurry. This is a problem that also occurs when a resin sheet is formed from an aqueous resin.

[0006] The cause of the problem that occurs when such an aqueous slurry is used is that a release film having a thermosetting silicone as a release layer on its surface is easily repelled when an aqueous coating liquid is applied, and agglomeration and the like occur. Probably because it occurred and could not be used. Similarly, polyvinyl carbamate, polyethyleneimine and the like containing a long-chain alkyl group are repelled, and a uniform coating film cannot be formed.

As a solution to these problems, there have been proposed a method of increasing the viscosity of the coating liquid and a method of adding a surfactant to reduce the surface tension of the coating liquid.

However, a high-viscosity coating liquid is difficult to level at the time of coating, and it is difficult to form a uniform coating film. In addition, the method of adding a surfactant has a drawback that the surfactant bleeds from the coating film and adversely affects the properties of the coating film. Therefore, none of these methods can be said to be satisfactory measures for improving coatability.
