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)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.

Ultraviolet light filter element

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).

Stabilizer system for polymer components of displays

An imaging member is prepared by applying to a support a heat-sensitive imaging layer which comprises at least one heat-sensitive polymer capable of undergoing transformation from a hydrophilic to hydrophobic state or hydrophobic to hydrophilic state, wherein the transformation occurs such that the activation energy Ea and the Arrhenius pre-exponential factor A associated with the transformation simultaneously fulfill the relationships: ln (A).gtoreq.0.4 Ea+8.84 and ln (A).ltoreq.1.69 Ea-14.37. The imaging member is useful in processless thermal lithographic printing.

Imaging member containing switchable polymers and method for use

The present invention is a photographic element including a support, having on one side thereof at least one silver halide emulsion layer, and having on the other side an antistatic layer, and a protective overcoat. The protective overcoat is farthest from the support; and is a continuous polyolefin coating.

Aqueous coatable protective polyethylene overcoats for imaging elements

The present invention provides a UVA protective eyeshield that includes a transparent substrate having dispersed therein an effective amount of 1-di-n-hexylamino-4,4-dicyanobutadiene.

Protective eyeshield

An analytical element for quantitatively assaying an analyte by measuring reflection density in the range 320 to 360 nm. The element comprises a reagent layer and a registration layer. One of such layers contains a dye which has a low absorbtivity band from 320 to 360 nm and a high absorbtivity band from 640 to 720 nm.
