Abstract
A process and composition for preparing a nonconducting surface for electroplating. The process comprises contact of the nonconductor with a reaction product of a stannous salt, a noble metal salt and halide ions in acidic solution having a pH not exceeding 3.5. The noble metal salt is present in a amount of from 0.01 and 2.5 grams per liter. The weight ratio of tin to noble metal preferably varies between 150:1 to 700:1. Following contact with the tin-noble metal composition, the surface is contacted with a solution of a sulfur salt able to react with tin and the noble metal to form a sulfide and then electroplated.
