ABSTRACT:
The harmful effects exhibited by excess silica (Si.sub.2 O) in electroless metal deposition solutions can be controlled by the use of certain amines. The amines can be prepared in separate solutions or can be incorporated into usual plating solutions to effectively control the effects of excess silica present. The amines can be shown to prevent voiding on glass substrates during silver deposition which often occurs with excess silica of amounts over 0.5 ppm.
