Vliv Na(+)/K(+) na kalafunová mýdla se složkou Pigment Red57:1.
The effect of a Na(+)/K(+) ionic ratio on the stability of colophony soap, prepadred from thermally treated an non-treated partially hzdrogenated colophoniies. After the optimization of that ratio the colophony soap was applied to the synthesis of Pigment Red 57:1 and Pigment Red 52:2. The course of formation of pigment particles was follwed by means of RTD diffraction analysis and the pigment samples were coloristically. (en)
