ABSTRACT:
Deposit buildup on pad rolls in pigment dyeings and the filling up of engravings and screens in pigment printing are frequent problems in practice which in certain circumstances cause appreciable expenses (cleaning costs, stoppages). More or less all the binder systems in aqueous dispersion which are at present customary in practice tend to build up deposits and/or fill up holes. It has now been found, according to the invention, that the stated disadvantages can be avoided by using for the above purpose water-soluble 2-component binder systems and otherwise producing pigment dyeings in conventional manner.
