<p>The present invention provides an acrylic release agent precursor, which makes it possible to prepare an acrylic release agent efficiently as much as possible in a comparatively small ultraviolet dose, regardless of the component.An acrylic release agent precursor which contains a poly(meth)acrylate ester having a group capable of being activated by ultraviolet radiation and has a storage elastic modulus of 1 x 102 to 3 x 106 Pa at 20°C and a frequency of 1 Hz, wherein said precursor, after irradiation with ultraviolet radiation, has a contact angle of 15° or more to a mixed solution of methanol and water (volume ratio of 90/10) having a wetting tension of 25.4 N/m.</p> |
