Title:
RELEASE SHEET AND ADHESIVE BODY
Document Type and Number:
WIPO Patent Application WO/2016/068196
Kind Code:
A1
Abstract:
This release sheet 1 has a substrate 12 and a release agent layer 11 that is provided atop the substrate 12. The release agent layer 11 is composed of a cured product of a release agent composition that includes 50 mass% or more of a diene polymer. The Mooney viscosity (ML1+4 (100 °C)) of the diene polymer, measured at 100 °C conforming to JIS K6300, is 25-70, and the ratio (TCp/ML1+4 (100 °C)) between the Mooney viscosity (ML1+4 (100 °C)) and the viscosity (TCp) of a toluene solution of the diene polymer is 2.2 or less. This makes it possible to provide a release sheet and adhesive body with which the imparting of a negative impact to an electric component or the like can be sufficiently suppressed, the peeling speed dependency of the release force can be made small, and the occurrence of a zipping phenomenon can be suppressed.
