be applied using other known methods such as dipping spraying or flooding although with higher solids contents the coating compositions can contain the customary pigments stabilizers fillers etc as well as the other conventional auxiliary agents and additives since the binders of this invention possess the property of drying under oxidation it is usually unnecessary to add to coating compositions containing them additional resins as crosslinking agents it is of course possible to employ concomitantly other binders acting as crosslinking agents e g aminoplasts or phenolic resins especially suitable in these cases are commercially available aminoplasts or phenolic resins both of which carry methylol or alkoxymethyl groups see e g related u s application ser no 205 129 filed on even date whose disclosure is incorporated by reference herein furthermore the coating compositions of this invention can be utilized in combination with other conventional binders capable of anode deposition such as for example carboxy group containing hydrocarbon resins or epoxy esters the proportion of foreign resins in the total binder however is not to exceed 40 by weight the binders of this invention as well as the foreign resins serving as crosslinking agents can be processed by simple physical admixture to form coating compositions of this invention in many cases especially when using resins having a relatively low molecular weight it is advantageous to subject the mixture prior to further processing to a precondensation at an elevated temperature for example temperatures in the range of 70 u00b0 to 150 u00b0 c such precondensates normally show improved properties from a painting technology viewpoint as compared to the physical mixtures per se for electrophoretic deposition voltages can be.
