Process for making cationic latex

In a process for treating anionic dispersions so that they are compatible with cationic systems, it is known to add the dispersion to an excess of a cationic emulsifer and adjust the pH of the latex. It has now been found possible to make an anionic latex cationic by adding a cationic stabilizer to...

Zusammenfassung:	In a process for treating anionic dispersions so that they are compatible with cationic systems, it is known to add the dispersion to an excess of a cationic emulsifer and adjust the pH of the latex. It has now been found possible to make an anionic latex cationic by adding a cationic stabilizer to an anionic latex and lowering the pH provided the anionic latex contains a dispersing agent effective between the pH of 8.5 and 6.5.
