Abstract
A laminate having a semiconductor substrate, a UV-ray-transmissive support substrate, and an adhesive layer and a release layer disposed between the semiconductor substrate and the support substrate. The release layer is a film formed from a releasing agent composition containing a polymer of an ethylenic unsaturated monomer having a tert-butoxycarbonyl group, a photoacid generator, and a solvent.
