PRIORITY: CH 75-13530 17 Oct 1975. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The bactericidal action of Cu2O in vinyl acetate-vinyl chloride copolymer (I) [9003-22-9]-based paints for ship bottom is prolonged by Acridine Orange (II) [65-61-2], Brilliant Green [633-03-4], or Crystal Violet base [467-63-0] and optionally, boric acid stearyl cetyl ester (III) [10043-35-3]. Thus, a coating prepd. from a compn. contg.

Photosensitive mixture and its use in making printing plates

Photosensitive mixture and its use in making printing plates. Stahlhofen, Paul; Hsieh, Shane (Hoechst A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3246037 A1 14 Jun 1984, 25 pp.Several substances are used for example 467-63-0 which is its cas registry number. (German). (Germany). CODEN: GWXXBX. CLASS: IC: G03F007-00. APPLICATION: DE 82-3246037 9 Dec 1982. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Photosensitive compns. for the prepn. There are some commonly used reagents like 467-63-0 in this article. of printing plates having a low burning-in temp. without crosslinking and good keeping qualities are composed of a water-insol., aq. alk. soln.-sol. binder, an o- or p-quinone diazide, a diazonium salt polycondensate, or a mixt. contg. a compd. giving an acid on exposure to light and a compd. having 31 acid-cleavable COC group, and a thermal crosslinking agent of the formula I (R = H or alkyl). Thus, an electrochem. roughened and anodized Al plate was coated with a compn. contg. a 50% PhMe soln. of a 7,7-bis(hydroxymethyl)-5-oxa-1-nonanol-trimethyl orthoformate polyorthoester 2.80, 2-(4-ethoxy-1-naphthyl) 4,6-bis(trichloromethyl)-s-triazine 0.23, a cresol-HCHO novolak (softening point 105-120°) 3.30, hexamethylolmelamine hexamethyl ether 0.50, crystal violet 0.04, and butanone 90.00 parts, dried, exposed for 10 s to a 5-kW halogen lamp, and developed with an alk. developer to give a plate which was hardened by burning-in for 5 min at 190°. A II-free plate needed to be burned-in at 240° to reach the same resistance. ..
