Novel isothiouronium salts are herein described which correspond to the formula ##STR1## wherein R and R' are each independently hydrocarbyl or inertly-substituted hydrocarbyl of at least 4 carbon atoms; R.sub.1 -R.sub.4 are each independently alkyl or hydroxyalkyl of 1 to 4 carbon atoms, or R.sub.1 and R.sub.3 are joined to form a 5- or 6-membered heterocyclic ring; n is 0 or 1; and A.sup..crclbar. is an inert neutralizing anion. The isothiouronium salts are surprisingly effective dispersing agents and are used in forming electrodepositable latexes.
本文描述了新型的等硫代尿酸盐,其符合以下公式:##STR1## 其中R和R'各自独立地是至少具有4个碳原子的烃基或惰性取代的烃基;R.sub.1 -R.sub.4各自独立地是1到4个碳原子的烷基或羟基烷基,或者R.sub.1和R.sub.3连接形成5-或6-成员杂环;n为0或1;A.sup..crclbar.是惰性的中性化合物。这些等硫代尿酸盐是出乎意料的有效分散剂,并用于形成可电沉积乳液。
