  • Patent number: 8329893
    Abstract: The present invention relates to cellulose esters having low hydroxyl content for use in optical applications, such as liquid crystal display (LCD) films. Films made with low hydroxyl levels and a given ratio of non-acetyl ester to hydroxyl level have been found to have low intrinsic birefringence. Therefore, these films can be cast, molded, or otherwise oriented without an appreciable birefringence or optical distortion (i.e. retardation). Such features make these films useful in polarizer, protective, and compensator films as well as molded optical parts, such as lenses. Furthermore, it has also been found that resins of the present invention can also be made to have “+C plate” behavior either by melt or solvent based processing, a characteristic which is not typical of cellulose esters. Such +C behavior allows films to be produced having unique compensatory behavior. Other embodiments of the invention relate to methods melt casting films while minimizing birefringence formation.

  • Publication number: 20100292368
    Abstract: Object of the present invention is to provide an acrylic-resin-containing film which exhibits high transparency, high heat resistance, and markedly improved brittleness, a polarizing plate using the acrylic-resin-containing film which improves a yield of operation such as punching of a polarizing plate or bonding panels and a liquid crystal display device which can keep to exhibit excellent visibility in long-terms usage in harsh environment. These objects have been achieved by the acrylic-resin-containing film comprising a acrylic resin (A) and a cellulose ester resin (B), or comprising the acrylic resin (A), the cellulose ester resin (B) and at least a resin (D) which is other than the resins (A) and (B) and has a glass transition temperature Tg of 120-300° C. The film is characterized in that it has a haze of less than 2%, a tensile softening point of 120-150° C. and undergoes no ductile fracture.

  • Patent number: 7816434
    Abstract: Process for the production on metal or plastic surfaces of thin, hydrolysis-resistant, scratch-resistant and stain-resistant coatings, wherein the coating material can be applied directly to the cleaned metal surface and subsequently cross-linked by high-energy radiation, in particular UV radiation. The substrates can be coated in the form of strip and only subsequently brought into the required external shape. Coated substrates such as these are no longer susceptible to staining by food, cleaning agents or fingerprints and can also be rendered antibacterial. Objects coated in this manner are thus suitable for use in architecture, for interior fittings of buildings, in furniture-making as well as for ornamental applications, and in particular in households, in sanitary applications, in hospitals and in the food-processing and pharmaceutical industries.

  • Publication number: 20100203348
    Abstract: Some embodiments of the invention generally relate to a moisture barrier coating that is biodegradable and compostable. Some embodiments also relate to a coating that is dual ovenable. Such coatings may be used to increase moisture resistance and provide non-stick or release characteristics when applied to biodegradable and compostable disposable food packaging and food service items. In some embodiments, a plasticizer, an amide wax and optionally a rosin are added to a cellulose-ester-based coating to increase moisture resistance. In other embodiments, a biodegradable polymer, an amide wax, optionally a plasticizer, and optionally a rosin are added to a cellulose-ester-based coating to drastically increase moisture resistance. In still other embodiments, phospholipids or medium-chain triglycerides or increased levels of amide wax may be added to the either of the embodiments above to provide enhanced release characteristics.
