Abstract: A release resin composition that is excellent in thermal stability, for example, during extrusion molding and does not cause problems such as smoking and foaming during preparation of a compound product or extrusion molding and further does not contaminate metal rollers. The release resin composition can be formed into a release layer that does not cause migration of impurities to an adhesive layer being in direct contact with the release layer and therefore does not decrease the adhesive properties of the adhesive layer. The release resin composition includes a release agent (A) of which main component is a polymer compound having a weight average molecular weight of 10000 to 1000000 and containing an aliphatic group having 8 to 30 carbon atoms and includes a thermoplastic polymer (B) containing an olefin monomer and/or a polar monomer as a constitutional unit, wherein the amount of the release agent (A) is 0.1 to 20 parts by weight to 100 parts by weight of the thermoplastic polymer (B).

Abstract: A release sheet comprising a release substrate and a release layer which comprises cross-linked polyolefin, is formed at least one side of said release substrate, and has from 10 to 300 mN/cm of release force to an adhesive layer formed from a 2 packs type acryl-based adhesive agent. The said release sheet has an excellent heat resistance, solvent resistance, adhesion between a release layer and a release substrate and capability of direct transfer coating of an adhesive layer on a release layer.

Abstract: A release agent for forming a release layer contacting with an adhesive layer, comprising (A) a polyolefin having a weight-average molecular weight of not less than 1×104, which may contain a functional group, and (B) a hydrocarbon having a viscosity of 1 to 1×104 cP as measured at 23° C. according to JIS K-7117, a weight ratio of the polyolefin (A) to the hydrocarbon (B) being 97:3 to 60:40. Such a release agent provides a novel release agent that is usable as an alternative material of a silicone-based and fluororesin-based release agents.

Abstract: A release agent comprising (A) an olefin-based elastomer having a density of not less than 0.855 g/cc and less than 0.868 g/cc, and (B) an ethylene-?-olefin copolymer having a density of from 0.868 g/cc to 0.970 g/cc as main components, wherein the difference in average density between the components (A) and (B) is not less than 0.005 g/cc and the mixing weight ratio of the component (A) to the component (B) is from 90:10 to 10:90. Such a release agent contains no silicone-based components generating undesired gasses, can exhibit not only a good releasability to various adhesives but also a less fluctuation in peeling force, and can maintain a low peeling force even when the release agent is bonded to an adhesive and preserved under a heating condition.

Abstract: A release film having a release layer on at least one surface of a base film, the proportion of silicon atoms to carbon atoms (Si/C) in the surface of said release layer being not more than 0.01, the proportion of halogen atoms to carbon atoms (X/C) being not more than 0.1, the peel force of said release film being not more than 75 mN/cm, and the retained adhesion rate of said release film being not less than 80%. This release film contains substantially no silicon and halogen elements and is of the easy release type.
