Abstract: PURPOSE:To make improvement in polarization characteristic and wet heat resistance by specifying the syndiotactic content determined from the IR absorption spectra of a polyvinyl alcohol (PVA) polymer constituting a base material film to specific % or above. CONSTITUTION:This base material film for a polarizing film is formed by absorbing a dichromatic coloring matter on a base material film of PVA system and orienting the dye and has >=50% syndiotactic content determined from the IR absorption spectra of the PVA polymer constituting the base material film. This base material film for the polarizing film has the structure consisting of the PVA base material film on which the dichromatic coloring matter oriented in a specific direction is absorbed. More specifically, the film formed by absorbing polyiodine ion or the dichromatic dye as the dichromatic colring matter on a PVA film, then stretching the film to orient the dichromatic coloring matter is exemplified. The improvement in the polarization performance and wet heat resistance is made in this way.

Abstract: PURPOSE:To obtain the polarizing film for a color liquid crystal display body which is improved in wet heat resistance by controlling the density of a base material film consisting of a polyvinyl alcohol (PVA) and the (b) value in the color solid coordinates of an Lab system. CONSTITUTION:The density of the base material film consisting of the PVA is specified to 1.2980 to 1.3140g/cm , more preferably 1.3020 to 1.3130g/cm . The wet heat resistance is poor and the degree of polarization decreases drastically if the density is below 1.2980g/cm . The wet heat resistance is also poor if the density exceeds 1.3140g/cm . Such densities are, therefore, undesirable. The (b) value in the color solid coordinates of the Lab system of the polarizing film is specified to -2.0 to 4.0, more preferably -1.0 to 2.0. Blue is strong if the (b) value is below -2.0 and yellow is strong at >=4.0 in the case of using this film for a color liquid crystal display. Natural color reproducibility is unobtainable in both cases. The polarizing film which has the excellent wet heat resistance and is adequate for the color liquid crystal display device is obtd. in this way.

Abstract: PURPOSE:To improve wet heat resistance and to obtain the polarizing film of a neutral gray hue by treating a polyvinyl alcohol (PVA) film with an aq. soln. contg. a dissolution preventive agent for the PVA film after a heat treatment. CONSTITUTION:The concn. of the potassium iodide and the concn. of boric acid in an aq. soln. contg. the potassium iodide and boric acid after adsorption of iodine to the PVA film are adjusted to the desirable concn. and the treatment is executed at the most desirable temp. of the heat treatment in the treatment of the above-mentioned aq. soln. The dissolution preventive agent for the PVA film to be used as the post treatment thereof is preferably the agent which has the effect of substantially preventing the dissolution of the PVA film during the treatment; above all, an aq. soln. of the boric acid or borax has low toxicity, is easy to handle and is highly effective in changing the hue to the neutral gray. The wet heat resistance of the polarizing film is improved in this way and the hue thereof is made into the neutral gray.
