Abstract
There is disclosed a casting film which is used for producing a ceramic green sheet and which comprises a substrate film (e.g. polyethylene terephthalate film) and a releasing layer formed thereon comprising a mixture of a silicone based releasing agent (e.g. addition reaction type silicone based releasing agent) and a cellulose derivative (e.g. ethyl cellulose, methyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose or hydroxypropyl cellulose). The casting film has excellent wettability of ceramic slurry and moderate releasability for the ceramic green sheet, and prevents the occurrence of repelling even in the case of the ceramic slurry being coated in a small thickness, and also the occurrence of lifting or peeling off of the green sheets even in the case of the ceramic slurry being repeatedly coated.
