PURPOSE:To provide an ink composition for screen printing capable of forming a resin layer on which an electroless plating shows ready adhesion, prepared by blending a thermosetting resin, a diene rubber and a solvent having a specified composition. CONSTITUTION:The composition contains a diene rubber and a thermosetting resin as solid components in the ratio of 0.1-10 by weight. It also contains a first solvent which is a good solvent for both the resin and the rubber and a second solvent which is a good solvent for the resin but a poor solvent for the rubber. The resin and the rubber account for 20-90% of the total weight of the resin, rubber and solvents. Preferred thermosetting resin is a phenolic resin, which effects crosslinking reaction with diene rubber to form a strong coating film. |
