摘要： Polymer film, coating, and molded article elements for use in a display device are described which comprise a polymer phase having molecularly dispersed therein an acid scavenger compound, a hindered amine light stabilizer compound and a hindered phenol antioxidant compound, wherein the hindered amine light stabilizer compound and the hindered phenol antioxidant compound are present at a weight ratio of from 20:1 to 1:20, and the weight ratio of the acid scavenger compound to the total concentration of hindered amine light stabilizer compound and hindered phenol antioxidant compound is from 10:1 to 1:10. Use of a combination of an acid scavenger and a combination of two radical scavenger antioxidants dispersed in a polymer phase in accordance with the invention enables enhanced stabilization of the polymer when exposed to high heat and/or humidity condition, which has been found to be especially desirable when applied to polymer layers laminated into displays (e.g., polarizers in liquid crystal displays).

摘要： Ultraviolet light absorbing polymer film, coating, or molded article UV filter elements are described which comprise a polymer phase having molecularly dispersed therein a) a first ultraviolet absorbing dibenzoylmethane compound of formula (I) 1 where R1 through R5 are each independently hydrogen, halogen, nitro, or hydroyxl, or further substituted or unsubstituted alkyl, alkenyl, aryl, alkoxy, acyloxy, ester, carboxyl, alkyl thio, aryl thio, alkyl amine, aryl amine, alkyl nitrile, aryl nitrile, arylsulfonyl, or 5-6 member heterocylce ring groups, and b) a second ultraviolet light absorbing compound which absorbs ultraviolet light at a wavelength for which the first compound is deficient at absorbing. In particular embodiments, the second ultraviolet light absorbing compound may comprise a hydroxyphenyl-s-triazine, hydroxyphenylbenzotriazole, formamidine, benzoxazinone, or benzophenone compound. In a specific embodiment of the invention, the above UV absorbing compounds are employed in cellulose acetate film for the fabrication of a protective film for polarizers for use in display applications.
