Document Type and Number:
WIPO Patent Application WO/2023/181621
Kind Code:
A1
Abstract:
This temporary fixing composition is characterized by containing the following (A)-(B), and having a storage elastic modulus at 23 °C of at most 0.66 GPa. (A) is a bifunctional (meth)acrylate having a cyclic skeleton, and (B) is a photoradical polymerization initiator. A cured body was obtained by: sandwiching the temporary fixing composition between PET films; spreading the same to a thickness of 50 μm; and curing the same using a UV-LED (center wavelength of 405 nm, illuminance of 100 mW/cm2) under the conditions of an integrated light quantity of 5,000 mJ/cm2.
