The results showed that the stearates can accelerate the development of PTG material. The addition of NiSt2 greatly increased the maximum density and the sensitivity together with a slight fog increase. However the addition of BaSt2 and CaSt2 did not make such great increase in the maximum density and the sensitivity, together with a slight fog decrease.
