上述したような連続多孔性弾性体は合成樹脂を主原材料とするために、親油性であって、親水性ではない。特許文献１〜４に記載される連続多孔性弾性体も親油性である。従って、特許文献１〜４に記載されるような連続多孔性弾性体は印版などの親油性であることが望まれる素材の場合は構わないが、親水性であることが望まれる素材として使用する場合、吸水性が悪いなどの問題が存在した。 Since the continuous porous elastic body as described above uses synthetic resin as a main raw material, it is oleophilic and not hydrophilic.

When doing so, there were problems such as poor water absorption.
