Acrylic release agent precursor, release agent article, and process for producing release agent article
Suwa of 3M, Minnesota developed 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.times.10.sub.2 to 3.times.10.sub.6 Pa at 20.degree. C. and a frequency of 1 Hz, wherein said precursor, after irradiation with ultraviolet radiation, has a contact angle of 15.degree. or more to a mixed solution of methanol and water (volume ratio of 90/10) having wetting tension of 25.4 N/m.   (RDC 1/24/2011)
