Disclosed is a film suitable for improvement of luminance, contrast and view angle of a liquid crystal display. Specifically disclosed is a retardation film having a thickness of 30-500 &#x3bc;m, a light transmittance of not less than 85%, and an Nz factor of not less than 10.

Retardation film

The oxygen-absorbing package of the present invention is produced by packaging an oxygen-absorbing composition comprising, as an effective component, an iron powder containing a fine iron powder passing through a 200-mesh standard sieve in an amount of 5% by weight or less by an air-permeable packaging material using an automatic filling-packaging machine. By using the above oxygen-absorbing composition, the iron powder is prevented from being partially scattered to attach to the outer surface of the oxygen-absorbing package during the industrial packaging operation using the automatic filling-packaging machine of high productivity, thereby enabling to obtain an oxygen-absorbing package capable of preserving products for a long period of time without contamination and color change during the storage.

Iron powder-based oxygen-absorbing package and production method thereof

An oxygen-absorbing composition for a low-humidity environment includes a reduced metal and an accelerator having at least one of iodide and bromide. The accelerator may have at least one of a metallic iodide salt and a metallic bromide salt. The reduced metal and the accelerator may be included in a dry state and the oxygen-absorbing composition may take the form of particles. The oxygen-absorbing composition may be a resin composition made by kneading an oxygen absorber with a thermoplastic resin.

Oxygen-absorbing composition, oxygen-absorbing resin composition,

The present invention provides an oxygen-absorbing resin composition, which is capable of sufficiently causing the oxygen-absorbing reaction even in a low-water environment, and also provides a packing material, packing method and package using such oxygen-absorbing resin composition. This invention is an oxygen-absorbing resin composition which contains a resin and an oxygen absorber which is made by coating iron powder with sodium iodide and potassium iodide. In a multi-layered film formed from this resin composition, iron particles coated with sodium iodide, etc. is dispersed in an oxygen-absorbing resin layer 4. Since a reaction accelerator of the oxygen absorber contains sodium iodide and potassium iodide as its principal component, this multi-layered film sufficiently absorbs oxygen in a low-water environment.
