ABSTRACT:
Synthetic resins containing quaternary sulfonium base groups are prepared by reacting an epoxy-group containing material with a sulfide in the presence of an acid. The resins may contain epoxy groups or they may be essentially epoxy-group free, and may optionally contain oxyalkylene groups. When dispersed in water, the aqueous dispersion preferably contains boron. The resultant dispersion can be applied to a wide variety of substrates by electrodeposition and will deposit on the cathode to provide coatings of unique properties, including high resistance to corrosion and staining.
