    Abstract: In a process for the manufacture of a planographic printing plate which requires no wetting a roughened metallic support is provided with a dispersed layer of polytetrafluoroethylene containing a reducing agent and then treated with a solution containing a noble metal salt, thus forming nuclei of noble metal salt. The layer is then treated with a nickel-plating solution until a continuous nickel layer has been deposited and the deposited nickel layer is then reinforced by electroplating and deactivated by heating to 90* to 100*C, whereupon the dispersed polytetrafluoroethylene layer is sintered at temperatures between 380* and 400*C.

    Abstract translation: 在不需要润湿的平版印刷版的制造方法中,将含有还原剂的聚四氟乙烯的分散层进行粗化,然后用含有贵金属盐的溶液进行处理,从而形成贵金属盐的核 。 然后将该层用镀镍溶液处理直到连续的镍层沉积,然后通过电镀加强沉积的镍层,并通过加热至90℃至100℃使其失活,于是分散的聚四氟乙烯层在温度 380〜400℃
