Process for the manufacture of synthetic resins with urethane groups, which also contain carboxyl groups and can be diluted with water
Abstract
Abstract The present invention relates to a process for the manufacture of thermosetting synthetic resins with urethane groups, which contain carboxyl groups and masked isocyanate groups and can be diluted with water, and which are manufactured by reaction of a compound (a) which contains alcoholic hydroxyl groups and carboxyl groups, with a masked isocyanate (b) in inert organic solvents. The present invention also relates to the use of the synthetic resins manufactured according to the invention as binders in coating agents for electrophoretic lacquering. The following advantages are achieved by the process of the present invention: Binders which can be diluted with water and are suitable for the electrophoretic coating process are obtained, which are distinguished by very good throwing power and by very good resistance of the stoved films to washing lyes or aqueous sodium chloride solution at 0* to 100*C.
