Two-layer process for applying antistatic compositions to polyester supports. Miller, Conrad Erve (du Pont de Nemours, E. I., and Co. 25214-36-2 is the cas registry number of certain chemical which is used as reagents here., USA). Eur. Pat. Appl. EP 191302 A1 20 Aug 1986, 28 pp. DESIGNATED STATES: R: DE, FR, GB, LU, NL. (European Patent Organization) CODEN: EPXXDW. CLASS: ICM: C08J007-04. ICS: G03C001-82; C09K003-16. APPLICATION: EP 86-100379 14 Jan 1986. PRIORITY: US 85-691768 16 Jan 1985.Several reagents with their cas registry numbers 25038-59-9 and 58048-89-8 are used here. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 77 Antistatic and byproduct-free backings for photog. film on a polyester support are prepd. by applying a layer contg. a water-sol. elec. conductive polymer having COOH groups and optionally a hydrophobic polymer having COOH groups, drying the first layer, applying an aq. polyfunctional aziridine, and drying the second layer. Thus, a PET support was coated with 25% aq. 3:1 Na styrenesulfonate-maleic anhydride copolymer (I) (mol. wt. 5000), dried, coated with aq. pentaerythritoltris[b-(N-aziridinyl)propionate] (II) (16 g/3600 g H2O), and dried to give a bilayer coating exhibiting water-resistance >10 rubs and surface resistivity 8.6 ′ 109 and 4.9 ′ 108 W/cm2 before and after water-resistance testing, resp., compared with poor resistance, 1.9 ′ 109, and 2.4 ′ 1012, resp., for single layer contg. I and II. ..
