Abstract: PURPOSE:To provide a laminated film hard to tear, excellent in pinhole resistance, reduced in the thickness of its support and increased in vapor deposition properties and slitting properties by laminating a polyester film specified in its thickness to the single surface or both surfaces of a support film composed of a polyphenylene sulfide film by close bonding strength releasable from the support film. CONSTITUTION:In a laminated film wherein a polyester film having a thickness of 0.2/1.5mum is laminated to the single surface or both surfaces of a support film by close bonding strength releasable from the support film, the intrinsic viscosity of the polyester film is 0.55-1.5 and the support film is composed of a polyphenylene sulfide. The polyester film is a uniaxially or biaxially oriented film of a resin composition composed of a polymer or copolymer wherein 70mol.% or more, pref., 85mol.% or more of polymer bonding chains are bonded by an ester bond.

Abstract: PURPOSE:To release without damaging documents stuck on or the like and making bonding again after releasing impossible by coextruding a layer (protection layer) constituting an opacifying layer and adjacent to a transparent resin layer and laminating them by means of bonding force to be able to release. CONSTITUTION:A layer (protection layer) composed of an opacifying layer, a transparent resin layer A and an adhesive layer laminated in said order and constituting the opacifying layer and adjacent to the transparent resin layer A is coextruded with at least the transparent resin layer A and laminated by bonding force to be able to release. It is preferable that the transparent resin layer A and the protection layer are laminated respectively in the state of being divided clearly when the two layers are coextruded and laminated by using the resin suitable for the purpose. The structure is simplified by said arrangement to make the manufacturing cost lower, and also when the laminate is used as a secret label, it is impossible to bond again once the same is released. Thus, a secret label for superior privacy protection, prevention of alteration and the like is manufactured.

Abstract: PURPOSE:To obtain the title film low in thermal degradation, excellent in mechanical properties, Freon resistance, etc. and suitable for dielectrics, etc. by specifying the content of poly-p-phenylene sulfide oligomer having a specified MW. CONSTITUTION:In producing poly-p-phenylene sulfide by, for example, a process comprising reacting sodium sulfide with a p-dihalobenzene in N- methylpyrrolidone, the polymerization temperature, the polymerization time, the kinds and amounts of adjuvants used (e.g., sodium acetate), the time and temperature in washing with an organic solvent after polymerization, etc. are specified. In this way, poly-p-phenylene sulfide wherein the content of poly-p- phenylene sulfide oligomer of an MW in the range of 300-2,000 is 0.1-2wt.% based on the entire polymer can be produced. This polymer is molded into a film, and this film is biaxially stretched to obtain the purpose biaxially oriented polyphenylene sulfide film.
