る現象などがその例である。Prior Art and Problems With the diversification of uses for release treated substrates, such as release paper in adhesive tapes, which have films made of silicone release agents on the front and back sides of thin substrates, conventional A problem has arisen in that one type of material having substantially the same peeling force is not sufficient for the intended use. Examples include the phenomenon in which the adhesive layer remains on the back side of the release paper when the adhesive tape is rewound at high speed, and the phenomenon in which the adhesive layer peels off between the tape base material and the release paper.

した。Means for Solving the Problems The present inventors have overcome the problems described in the following while responding to demands such as control of peeling force ranging from light peeling to one peeling and peeling balance according to peeling speed. As a result of intensive research to develop a mold release treatment substrate, we discovered a new finding that there is a causal relationship between the crosslinking density in the cured film of silicone mold release agents and the speed dependence of the peeling force. did.

１００）ｔの厚さが一般的で委る。The release-treated substrate of the present invention is produced by applying a film made of a silicone-based release agent to the front and back surfaces of a thin substrate so that the crosslinking densities thereof are different (preferably, the difference in crosslinking density is 10% or more). ◇This causes a difference in the speed dependence of the peeling force on the front and back surfaces of the release-treated substrate.Generally, the speed dependence of the peeling force tends to decrease as the crosslinking density increases. The thickness of the film is not particularly limited, and the object of the present invention can be achieved with the same thickness as in the past.Specifically, the thickness is 0.1 to 1.

ができる。Effects of the Invention According to the present invention, since the crosslinking densities of the silicone release coatings on the front and back surfaces are different, it is possible to obtain a release-treated substrate in which the speed dependence of the peeling force on the front and back surfaces is different. As a result, it is possible to form a release-treated substrate that has a balance of peeling force on the front and back surfaces that corresponds to the application.
It is possible to effectively prevent the adhesive layer from remaining on the back side of the release paper and from peeling between the tape base material and the release paper.

、テープと剥離紙との間で分離が生じた。A natural rubber-based pressure-sensitive adhesive was applied onto the cured film on the low crosslinking density side of the release paper so that the thickness after drying was 0.06 nm, dried, and then wound into a roll. Then, when the rolled material was unwound at a speed of 3 to 100 m/min, it showed good unwinding properties, and no separation occurred between the tape and the release paper. I x 10m
In an unwinding test under the same conditions of a roll of pressure-sensitive adhesive tape obtained according to the example except that a hardened film of ol/f was provided, separation occurred between the tape and the release paper.
