PCT No. PCT/JP85/00323 Sec. 371 Date Feb. 26, 1986 Sec. 102(e) Date Feb. 26, 1986 PCT Filed Jun. 6, 1985 PCT Pub. No. WO86/00564 PCT Pub. Date Jan. 30, 1986.The present invention relates to a method of manufacturing a release paper characterized in that a mixture of polyolefin and a silicone release agent compatible therewith comprising a reaction product of polymethyl hydrogen siloxane, vinyl group-containing poly-dimethyl siloxane and at least one of olefins or polyolefins having one or more double-bonds is extruded onto a substrate of paper, fabric, film etc., the laminate is heat treated for the release agent contained in the mixed layer of the above-mentioned laminate to bleed onto the surface of the mixed layer to be thus localized and the localized release agent is fixed by curing. The release agent's compatibility with the polyolefin, and this film forming and stretching properties are improved, and since the release agent of high concentration is localized and fixed by curing on the surface of the release agent layer, only a small amount of the release agent is needed. |
