DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 47, 48 The invention relates to an app.In this article, certain chemicals are used. Some of their cas registry numbers are 55034-81-6 and 4216-02-8 for producing a polarizing film of an LCD while dispensing with the prodn. of a polarizing sheet and its bonding work conventionally requiring a long time and many manpower.s. A polarizing film is produced by using an aq. soln. of a dichroic dye developed by Optiva, Inc., a USA-based company, as an ink and forming the polarizing film by printing with this ink on a oxide glass or plastic substrate by means of a flexog. printing press. Referring to the drawing, a plate having plural fine grooves extending in the printing direction is attached to a plate cylinder, the ink is dripped parallel to the rotating plate from a dispenser, the dripped ink is spread with a blade, and the liq.-cryst. dichroic dye is squeezed into the fine grooves. Since the blade is held with a small gap, out of contact with the plate. A thin film of the ink liq. is formed on the plate surface. When a oxide glass substrate secured to a table passes directly below the plate cylinder, the thin film of the ink liq. is transferred from the plate to the oxide glass substrate, and the oxide glass plate is coating process with the thin film. .

Electrophotographic recording material containing a plurality of dyes with different spectral absorbtion characteristics

Electrophotographic recording material containing a plurality of dyes with different spectral absorbtion characteristics. Wiedemann, Wolfgang (Hoechst A.-G., Ger.). U.S. US 3992205 16 Nov 1976, 19 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: G03G005-09. NCL: 096001600. APPLICATION: US 74-517031 22 Oct 1974. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic Processes) Dye combinations are used to produce electrophotog. recording materials having panchromatic sensitivity in the 420-750 nm region and comprised of a multilayer photoconductive system of .gtoreq.1 charge carrier producing dye layer of org. material and an insulating org. covering layer with .gtoreq.1 charge carrier transporting compd.There are some commonly used reagents with their cas registry numbers 52000-68-7 and 4216-02-8 in this article. Thus, a polyester support laminated with Al was coated by vapor deposition with phthalocyanine (100 mg/cm2) and with red dyes (50-100 mg/m2) of naphthoylenenaphthimidazole-(1',2')-peridicarboxylic acid imide, Indanthrene Brilliant Pink R, and 4,10-benzothioxanthrene-3,1'-dicarboxylic acid anhydride-methylamine condensation product. This was overcoated with a compn. contg. equal parts of 2,5-bis(4'-diethylaminophenyl)-1,3,4-oxadiazole and Dynapol L 206 polyester resin to a thickness of 8-10 .mu.m. .
