Abstract
A lubricant sheet for a magnetic tape cassette characterized in that at least one side of a base incorporating an antistatic agent is provided with a release type silicone coating. This lubricant sheet combines the transparency derived from the use of the clear base and coating materials with the low friction characteristic and the antistatic property to suit the application as such for transparent tape cassette cases.
