REACTIVE AIR PERMEATION RESISTANT POLYMER FOR PRODUCTION OF ELECTRODE SUBSTRATE FOR LIQUID CRYSTAL DISPLAY PANEL AND ELECTRODE SUBSTRATE FOR LIQUID CRYSTAL DISPLAY PANEL USING THE SAME
PURPOSE:To maintain stable performance over a long period of time even under severe use conditions by using the reactive air permeation resistant polymer formed by polymerizing a monomer mixture consisting of a specific ethylenic unsatd. amide monomer and a vinyl polymerizable monomer in the copresence of a vinyl alcohol polymer as a substrate material. CONSTITUTION:The monomer mixture (M) consisting of the ethylenic unsatd. amide monomer (Ma) expressed by formula I and the vinyl polymerizable monomer (Mb) having a carboxyl group in the molecule is polymerized in the copresence of the vinyl alcohol polymer (V) to obtain the reactive air permeation resistant polymer. In formula I, R1, R2 are H or lower alkyl group; R3 is 1 to 4C alkylene group. The molar ratio of (Ma)/(Mb) or this reactive air permeation resistant polymer (Ma)/(Mb) is 0.05 to 5.0 and the weight ratio of (M)/(V) is 0.02 to 0.5. The layer 2 consisting of such reactive air permeation resistant polymer is provided on one or both surfaces of a base material layer consisting of a non-optically active transparent film or sheet having =80nm retardation value, by which the electrode substrate is formed.
