PROBLEM TO BE SOLVED: To provide a release sheet for manufacturing a printed board excellent in characteristics such as releasability, heat resistance, abrasion resistance or the like, high in safety and easy to handle. SOLUTION: A coating agent contains polyorganosiloxanes, especially a polymer (A) comprising 1-80 wt.% of a monomer (a) having a carbon-carbon unsaturated double bond and a polyorganosiloxane chain in one molecule thereof, 10-80 wt.% of a monomer having a carbon-carbon unsaturated double bond and a crosslinkable functional group in one molecule thereof and 0-89 wt.% of a monomer (c) having a carbon-carbon unsaturated double bond in one molecule thereof other than the monomers (a) and (b), and a polymer (B) containing 10-100 wt.% of the monomer (b) and 0-90 wt.% of the monomer (c). This coating agent is applied to at least a part of an aluminum foil to obtain a release aluminum foil having a coating layer for manufacturing the printed board. COPYRIGHT: (C)2003,JPO
