Abstract: A coating composition comprising a) an organic film-forming binder; and b) a corrosion-inhibiting amount of a substantially water-insoluble mono- or poly-basic salt of:i) a ketoacid having the formula I: ##STR1## in which m and n, independently, are 0 or an integer from 1 to 10 provided that the sum of m and n is at least 1; A is C.sub.1 -C.sub.15 alkyl, C.sub.2 -C.sub.15 alkenyl, optionally substituted C.sub.3 -C.sub.12 cycloalkyl, C.sub.2 -C.sub.15 alkyl interrupted by one or more O-, N- or S-atoms, optionally substituted C.sub.6 -C.sub.10 aryl, optionally substituted C.sub.7 -C.sub.12 aralkyl, optionally substituted C.sub.7 -C.sub.12 aralkenyl, a heterocyclic residue or a ferrocenyl residue; R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are the same or different and each is a substituent A, hydrogen, OH, O-C.sub.1 -C.sub.15 alkyl, NH.sub.2, NH(C.sub.1 -C.sub.15 alkyl), N(C.sub.1 -C.sub.15 alkyl).sub.2, CO.sub.2 H, CO.sub.2 (C.sub.1 -C.sub.15 alkyl), SO.sub.3 H, P(O) (OH).sub.2 P(O)(OH)(O-C.sub.1 -C.sub.
Abstract: An ink comprising a dye and a liquid medium for dissolving or dispersing a dye, wherein the liquid medium comprises an alkyl alcohol having 2 to 4 carbon atoms, in which at least one of the hydrogen atoms is substituted by a halogen atom.
Abstract: Mixtures of light colored bis(C.sub.8 -C.sub.22 fatty acid) alkylene diamides, C.sub.8 -C.sub.22 fatty acid esters, and, if desired, metal soaps of C.sub.8 -C.sub.22 fatty acids can be obtained if, in a melt containing fatty acids with 8 to 22 carbon atoms, a part of the fatty acids are condensed to the corresponding fatty acid diamides with diamines of the general formula NH.sub.2 --R--NH.sub.2, in which R is a straight chain, branched, or cyclic alkylene group with 2 to 12 carbon atoms; a part of the fatty acids are esterified with fatty alcohols with 8 to 22 carbon atoms and/or multifunctional alkanols with 2 to 15 carbon atoms and 2 to 6 hydroxyl groups; and, if desired, a part of the fatty acids are converted to the corresponding metal soaps with basic compounds of divalent metals. The condensation with the diamines is carried out before the esterification of the fatty acids with fatty alcohols and/or multifunctional alkanols. The mixtures so obtained can be used as additives in plastics.
