It was our purpose to study the relationships between rheological properties and mixed ratio of pigments for the suspension containing two kinds of pigments in linseed oil. In our previous studies, it was obvious that the Brilliant Carmine 6 B showed was a remarkable difference of the ability to make the internal structure from chrome yellow 10 G on suspension in a boiled linseed oil ; the former was stronger than the latter. Then, we measured viscoelasticity, viscosity at the steady flow and yield value of five suspensions containing different mixed ratio of those pigments.<BR>As the results, we recognized that there was the maximum value of the viscoelasticity at a small-amplitude near the mixed ratio (vol.) 1 : 1. On the other hand, under the steady flow we obtained, the linear relationship between the viscosity or yield value and the mixed ratio of those pigments.
