説明

An investigation was made to determine the effect of structure of surface active agents on their azopigment dispersion power by “Semimicro Azopigment Method”.<BR>The dispersing powerr becomes higher with increasing carbon numbers in anionics such as sodium alkyl sulfates, sodium alkyl sulfonates, and disodium salts of α-sulfo fatty acid, and with increasing ethylene oxide moles in nonionics such as POE nonyl phenyl ethers, POE lauryl ethers and POE oleic esters.<BR>Thermal stability of azopigment dispersion was most excellent when sodium methyl naphthalene sulfonate formalin condensate was used as a dispersing agent.
