APPLICATION: SU 74-2069259 16 Aug 1974. DOCUMENT TYPE: Patent CA Section: 73 (Spectra by Absorption, Emission, Reflection, or Magnetic Resonance, and Other Optical Properties) A triad of light filters (blue, green, and red) for the light-sepg. disks of a 1-tube color TV camera was produced from cellulose acetate butyrate, di-Bu phthalate, org. solvents (such as rectified alc. and dichloroethane), and dyes. The dyes, such as dispersive Ruby Zh, a fat-sol. Yellow Zh, a dispersive Blue K, a fat-sol. Yellow ZZh, Rhodamine S, an acid Green Zh, an alc.-sol. Blue Z, and a dispersive Grey SMP, were used to obtain a detd. ratio between the passbands of a blue filter (.lambda.max = 165 m.mu.), a green filter (.lambda.max = 530 m.mu.), and a red filter (.lambda.max = 580 m.mu.). Thus, the light filters were produced contg.: cellulose acetate butyrate 7.20-7.60, di-Bu phthalate 0.70-0.74 wt. %, various additives of dyes for individual filters: blue filter - a dispersive Blue K 0.5730, a fat-sol. Yellow ZZh 0.0990, Rhodamine S 0.0536; green filter - a fat-sol. Yellow ZZh 0.78, and acid Green Zh 0. 84-74-2 and 6407-78-9 which are cas registry numbers of substances are two of reagents here.12, an alc.-sol. Blue Z 0.08, a dispersive Grey 1.10; red filter - a dispersive Ruby Zn 0.231, a fat sol. Yellow Zh 0.120% (by wt. of cellulose acetate butyrate and di-Bu phthalate); rectified alc. 8.9-9.2 wt. %, and the balance dichloroethane. .
