積層されて焼成される。Ceramic green sheets are used to obtain multilayer ceramic capacitors, and are made by mixing raw ceramic powder with a binder such as a resin and forming it into a sheet. To make a multilayer ceramic capacitor, a plurality of the capacitors are laminated and fired after electrodes are formed on their main surfaces.

ため、３本ロールリバースコーターも良く使用されてい
る。By the way, ceramic green sheets are made of, for example, surface-treated polyethylene terephthalate film (surface-treated polyethylene terephthalate film).
A carrier film (T film) is circulated, a slurry of a viscous ceramic green sheet compound is supplied to it, and it is scraped off to a constant thickness with a doctor blade, dried, and the sheet is transformed into a carrier film. It is also manufactured using the doctor blade method, which involves peeling it off from the
When coating thin ceramic green sheets of 20 μm or less, a 3-roll reverse coater is also often used to accommodate surface-treated PET film and mechanical precision.

。As shown in FIG. 5, a three-roll reverse coater is configured such that, for example, a carrier film 1 of the above-mentioned surface-treated PET film is rotatably provided between two rolls A and B, and the carrier film 1 of the surface-treated PET film is rotatably provided adjacent to the carrier film 1, and the rolls are rotated in opposite directions. The C-roll and the N-roll are provided so as to be in contact with each other, and the slurry 2 of the ceramic green sheet compound is supplied between these rolls, and the interval between these rolls is adjusted to form a uniformly thick slurry coating layer on the C-roll. The ceramic green sheet 3 is obtained by contacting and transferring the green sheet to the accompanying carrier film 1, drying it with a dryer (not shown), and peeling it off.

揮させている。In both the doctor blade method and the three-roll reverse coater method, the carrier film is surface-treated.The PET film is surface-treated by forming a silicone-based release agent layer on the PET film. When forming a ceramic green sheet using such a film as a carrier film, especially when forming a thin ceramic green sheet of 20μ or less, when peeling the sheet from the release layer of the carrier film, Static electricity is likely to be generated. Therefore, as shown in FIG. 3, an antistatic layer 5 is provided on the PET film 4, and a silicone mold release layer 6 is provided thereon, or as shown in FIG. An antistatic agent is mixed into the upper silicon mold release layer 7 to exhibit an antistatic effect.

When thin ceramic green sheets of 0μ or less are formed from a carrier film treated with antistatic treatment, even if the generation of static electricity is prevented when peeling, it is not possible to stack the obtained ceramic green sheets on top of each other and store them. Since it is not possible to prevent the generation of static electricity when the surface is rubbed during the process of attaching electrodes and the like to the ceramic green sheets, the ceramic green sheets stick to each other or to other objects, making them difficult to handle.
本発明の目的は、担体フィルムを用いて粘稠流動体から
シートを成形する場合その剥離時に帯電防止性があるの
みならず、その成形体そのものにも帯電防止性を付与す
ることにある。An object of the present invention is to provide not only antistatic properties when peeled off when a sheet is formed from a viscous fluid using a carrier film, but also to impart antistatic properties to the molded product itself.

状物成形用担体フィルムを提供するものである。In order to solve the above problems, the present invention provides a carrier film for forming a sheet-like object, in which a viscous fluid is applied to form a sheet-like object, and this sheet-like object is peeled off. The present invention provides a carrier film for forming a sheet-like article, which has a soluble antistatic agent-imparting layer on the surface that is in contact with the viscous fluid.

ときでも静電気の発生を防止することができる。For example, a ceramic green sheet is formed using a carrier film that has an antistatic agent-imparting layer containing an antistatic agent that is soluble in the viscous fluid on the surface that comes into contact with the viscous fluid. An inhibitor can be applied to the formed ceramic green sheets to prevent the generation of static electricity even when their surfaces are rubbed.
