  • Optical compensation film, polarizing plate and liquid crystal display
    Patent number: 8753726
    Abstract: An optical compensation film and a liquid crystal display characterized in that in a scattered-light intensity measurement for a film with an incident light with 90° in a scattered light profile of a goniophotometer, in the case of measuring so as to detect a scattered light intensity at the position of 130° from a light source, a difference in scattered light intensity between the case where a film slow axis is installed horizontally on a sample stand and the case where the film slow axis is installed vertically is 0.05 or less.

  • Process for the preparation of nitrocellulose solutions having a low water content
    Patent number: 8388748
    Abstract: The present invention relates to the continuous preparation of alcohol- and plasticizer-free finished nitrocellulose solutions having a particularly low water content by partial distillative falling-film evaporation of comparatively water-rich, optionally emulsion-like crude nitrocellulose solutions which are preferably provided by dissolving nitrocelluloses of the customary solid forms offered, which are known to be initially water-moist as a result of the preparation, in preferably ethyl acetate.
