Document Type and Number:
Japanese Patent JP6947286
Kind Code:
B2
Abstract:
The present invention provides a release film comprising a base material and a release layer provided over the base material, wherein the release layer is a cured product of a composition containing a silicone resin having a reactive functional group and other polymerizing ingredients, and, as measured by XPS, when X is the silicon peak intensity for the surface of the release layer on the side facing away from the base material side, Y is the silicon peak intensity at a depth of 4.1 nm from said surface of the release layer, and Z is the silicon peak intensity measured when a silicone resin layer containing 90% or more polydimethylsiloxane has been formed, X is greater than Y, the ratio of X to Z is 40% or greater, and the ratio of Y to Z is 5 to 50%.
