Copper foil laminates: Copper foil laminates. (Matsushita Electric Works, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59140051 A2 11 Aug 1984 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B32B015-08; H05K003-38. APPLICATION: JP 83-14417 31 Jan 1983. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Section cross-reference(s): 43, 76 In lamination of a metal foil with an unsatd. resin-impregnated base sheet for elec. circuit boards, bond strength is improved by treating the foil with imidazole [288-32-4] or its deriv. and laminating the foil with the base sheet by an adhesive contg. a silane coupling agent. Thus, kraft paper was impregnated with a liquor contg. 60% (solids) maleic anhydride-phthalic anhydride-propylene glycol copolymer [25037-66-5]. Cu foil was treated with a liquor contg. 0.01% 5-nitrobenzimidazole [94-52-0], dried, and coated with Ripoxy R 802DA [83513-74-0] (vinyl ester resin) contg. 1.0% triethoxyvinylsilane [78-08-0]. The coated foil and five sheets of the impregnated paper were pressed together 10 min at 120° to give a laminate with high bond strength.

Lab., West Point, Pa., USA). J. Toxicol. Environ. Health, 2(4), 895-903 (English) 1977. CODEN: JTEHD6. DOCUMENT TYPE: Journal CA Section: 17 (Foods) Section cross-reference(s): 4, 1 The anthelmintic cambendazole (I) [26097-80-3] was rapidly metabolized to at least 13 urinary metabolites. Radioactivity was found in liver for weeks after a single dose in cattle, but even at 3 days' withdrawal, I and metabolites previously identified in urine accounted for only a small fraction of liver radioactivity. The radioactivity was ubiquitously distributed in protein and nucleic acid fractions, and 14C-labeled glutamic acid was identified, indicating incorporation of 14C into the endogenous pool. Part of the residual liver radioactivity at 7 days was convertible chem. to 5-nitrobenzimidazole [94-52-0], indicating a drug-related macromol. residue. However, data from rats fed radiolabeled steer liver indicate that the residue is minimally bioavailable and therefore of substantially less toxicol. concern than I itself.
