  • Electrodepositable coating compositions
    Patent number: 5120356
    Abstract: The present invention provides an aqueous coating composition comprising:a) an aqueous electrodepositable film-forming binder; andb) as corrosion inhibitor, an effective amount of the reaction product of i) cinnamaldehyde and ii) an amine having the formula R--(CH.sub.2).sub.n --NH.sub.2 wherein R is C.sub.1 -C.sub.12 alkyl, C.sub.6 -C.sub.10 aryl, C.sub.5 -C.sub.8 cycloalkyl or --NH.sub.2, and n is O or an integer within the range of from 1 to 10.
    Type: Grant

    Assignee: Ciba-Geigy Corporation
    Inventors: Emyr Phillips, Adalbert Braig
  • Anticorrosive surface coatings
    Patent number: 5102457
    Abstract: Compounds of formula I: ##STR1## in which R, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 are as defined in claim 1, are suitable as corrosion inhibitors in surface coatings for metals.
    Type: Grant
    Filed: April 10, 1991
    Date of Patent: April 7, 1992
    Assignee: Ciba-Geigy Corp.
    Inventors: Adalbert Braig, Emyr Phillips
  • Phenolic benzothiazole derivatives and their use as corrosion inhibitors
    Patent number: 5097039
    Abstract: Compounds of the formula I ##STR1## wherein R, R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 have the meaning given in claim 1 are formed by thermal rearrangement of the isomers of formula V ##STR2## especially in the presence of basic catalysts. The compounds are corrosion inhibitors for organic materials, in particular coating materials and lubricants. In these substrates they also act as antioxidants and light-stabilizers and are very stable to heat.
    Type: Grant

  • Phenolic corrosion inhibitors for coating materials
    Patent number: 4818777
    Abstract: Compounds of the formula I ##STR1## in which is independently hydrogen, alkyl, alkoxy, halogen, trifluoromethyl or nitro, R.sup.1 is hydrogen, alkyl, phenyl, substituted phenyl or furyl, R.sup.2 is hydrogen or alkyl, R.sup.3 and R.sup.4 are independently hydrogen, alkyl, allyl, aralkyl, alkoxy, halogen, phenyl or cyclohexyl, and R.sup.5 is hydrogen, alkyl or alkenyl, are good corrosion inhibitors for organic materials, especially for coating materials. They can at the same time also act as antioxidants and light stabilizers.
