PCT No. PCT/EP87/00713 Sec. 371 Date Nov. 20, 1989 Sec. 102(e) Date Nov. 20, 1989 PCT Filed Nov. 16, 1987 PCT Pub. No. WO88/03941 PCT Pub. Date Jun. 2, 1988.The invention relates to cathodic water-dilutable binders which contain primary amino groups neutralized with acids and introduced via ketimine groups. The binders have been prepared by reacting (A) a synthetic resin containing epoxy groups with (B) at least one compound which, in addition to a mercapto group which is reactive toward epoxy groups, also possesses at least one ketimine group, and, if required, (C) other modifying compounds, such as, for example, monocarboxylic acids and/or other primary and/or secondary amines, and have then been neutralized with an acid.
