Abstract:
1. A thermal transfer recordable release sheet comprising a substrate and a release agent layer of a release agent composition provided on at least one surface of the substrate, wherein said release agent composition comprises, as main components, a thermoplastic elastomer formed from at least one material selected from a group consisting of ethylene-propylene copolymers, ethylene-propylene terpolymers and ethylene-butene rubbers, as well as a polydimethylsiloxane, and a quantity of said polydimethylsiloxane within a release agent layer is within a range from about 2 to about 20 mass %, a quantity of said thermoplastic elastomer is within a range from about 80 to about 98 mass %, and said release agent layer has a coefficient of dynamic friction of greater than or equal to 0.3, wherein a silicon content of a surface layer of said release agent layer at a depth of 5 nm as measured by ESCA (Electron Spectroscopy for Chemical Analysis) is within a range from 5 to 30 atomic %.
