TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The polyester urethane polyol which the polyurethane adhesive gave chain with the isocyanate compound more than polyester polyol or bifunction with a single-piece or a mixture. It has a dimer fatty acid, its derivative(s), or hydrogenation bodies as a dibasic acid or glycol component. The adhesive-agent composition mixes with the epoxy compound. The base material is polyethylene terephthalate (PET), or polyethylene naphthalate (PEN); polyester base material of polybutylene terephthalate (PBT) or polycyclohexane dimethanol terephthalate (PCT); polycarbonate-type base material of polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF), polychlorotrifluoroethylene resin (PCTFE), or polyethylene tetrafluoroethylene (ETFE); fluorine-type base material of PTFE, tetrafluoroethylene perfluoro-alkyl vinyl ether copolymer (PFA), or tetrafluoroethylene hexafluoropropylene copolymer (FEP); or an acrylic-type base material. It is polyester base material with which less than or equal to1.5 wt.% and intrinsic viscosity have hydrolysis resistance of greater than or equal to0.5 dl/g in cyclic-oligomer content in 18000-40000. Preferred Product: The laminated body is made to interpose further the vapor deposition base material of vapor-deposited inorganic compounds, e.g. an aluminum foil base material, metal aluminum and silica, or an alumina, as a gas barrier layer. EXAMPLE - Polyurethane adhesive was mixed into polyester polyol which set the dimer fatty acid as the composition from the burette body of hexamethylene diisocyanate so that 10:1 by solid content ratio was used. Polyethylene terephthalate was 0.7 dl/g in oligomer content 0.5 wt.%, a number average molecular weight 19500, and intrinsic viscosity. The base material was 2-type multilayer film of three layers which provided the fine foaming type white polyethylene-terephthalate film in the intermediate layer, and an intermediate occupied 80%. The white polyethylene-terephthalate film was untreated. The sheet was made to laminate by dry-laminate method. The coating amount of the adhesive agent was adjusted 5 g/m2 in conversion of dry cleaning. Aging temperature was 50degreesC to five days. Evaluation showed the sheet to be excellent in hydrolysis resistance.
