Examples
Embodiment 1
[0041] (Preparation of release liner)
[0042] Silica is fixed to a thickness of 93 μm and a basis weight of 68.0 g / m with an isocyanate adhesive 2 and the density is 0.73g / cm 3 On each side of the wood-free paper, a clay coating (3 μm) was formed. A further silicone layer (0.8 μm) was formed on each side, resulting in a release liner.
[0043] (Preparation of pressure-sensitive adhesive sheet with release liner)
[0044] The release liner was removed from the double-sided adhesive tape (No. 500, manufactured by Nitto Denko Crop.). The release liner prepared above was applied to each side of the exposed adhesive layer to prepare a pressure-sensitive adhesive sheet with a release liner.
Embodiment 2
[0046] Silica was fixed with isocyanate adhesive to a thickness of 86 μm and a basis weight of 68.7 g / m 2 and density of 0.80g / cm 3 On each side of the wood-free paper, a clay coating (3 μm) was formed. A further silicone layer (0.8 μm) was formed on each side, resulting in a release liner.
[0047] (Preparation of pressure-sensitive adhesive sheet with release liner)
[0048] The release liner was removed from the double-sided adhesive tape (No. 500, manufactured by Nitto Denko Crop.). The release liner prepared above was applied to each side of the exposed adhesive layer to prepare a pressure-sensitive adhesive sheet with a release liner.
