 1.Oxygen absorption film and quinones
 
    Anthraquinones are reduced to anthrahydroquinones by light in polymer films. And this anthrahydroquinone can absorb remaining oxygen in a tray.
    We have many anthraquinone derivatives that are soluble in organic solvent and pre-polymer.( WO99 / 10251,PCT / AU98 / 00671)
quinone:polymer
UV is irradiated to antraquinones in a polymer.
Anthraquinones are changed into anthrahydroquinones.

The polymer having anthraquinons becomes the polymer with oxygen absorption ability.
quinone:the polymer with oxygen
 2.Anthracene derivatives for the introduction to polymer
    Anthracenes generally respond to the light. They have the large intension of the absorption of ultraviolet ray near 250nm, and they emit the fluorescence.
    It is necessary that anthracene unit is pendent to polymer or put in the poloymer structure. Such a polymer expects to be thermally more stable and to have the photo-responsibility by the aromatic introduction.
    KAWASAKI KASEI CHEMICALS LTD. has synthesized many monomers with the above functional groups, passing by naphthohydroquinone, anthrahydroquinone and anthrone made by the original manufacturing method.
