IPC: B29K29/00
Filed: 1993-04-02
Abstract: PURPOSE:To improve polarization performance of a polarizing film even when the film is obtd. by uniaxial orientation at low temp., by uniaxially orienting a film produced by mixing polyvinylalcohol and one compd. selected from potassium halides and zinc halides with specified weight ratio, and uniaxially orienting. CONSTITUTION:This film is obtd. by mixing 0.01-20wt.% of one compd. selected from potassium halides and zinc halides to polyvinylalcohol(PVA), forming a film, and uniaxially orienting the film. If the mixing ratio is less than 0.01wt.%, the effect to improve orienting property of the PVA film is not enough. If the proportion exceeds 20wt.%, the film forming property decreases. The stretching rate of the oriented film is >=3 times, preferably >= 4 times. If the rate is less than three times, a polarizing film of high polarization property is not obtd. Thereby, the polarization performance of the polarizing film by low temp. orientation can be significantly improved, and the obtd. film has const. transmittance and excellent polarization performance.
