Abstract
Electrolytic development process of the ZnO-resin layer in the aqueous solution of 2, 3, 5-triphenyltetrazolium chloride (T. TC.) as the developing soln. was studied. Experiments were conducted on such electrolytic conditions as the electrodeposition efficiency, the image density vs quantity of deposited 1, 3, 5-tripheny formazan dye, the log exposure vs electrolytic current, polarographic analysis of the developing soln., and on such developing conditions as the temperature of developing soln., the elapsed time after exposure, the applied voltage, the developer concentration, the developing time, and moreover on such characteristics of the layer as the effect of ball milling time compared to the photocurrent measured by a surface-type cell. The mechanism of the electrolytic system is discussed in relation to the results of the polarographic study. Four quadrant relations of the whole conditions are proposed.
The conclusions;
1) The best conditions for a standard development are; the temperature of developing soln. 20°C, the applied voltage 10V., the T. T. C. concentration 1%, and the developing time 10sec.
2) A good agreement is found between the electrolytic characteristics of the ZnO resin layer and the photocurrent characteristics of the layer measured by surface-type cell. This indicates that the electrodynamic property of the layer will greatly influence the characteristics of the system.
3) The mechanism of the electrolytic system could be explained from the results of the polarographic analysis and from the consideration of the equivalent circuit diagram for the system.
