SILICONE-BASED ADHESIVE COMPOSITION, METHOD FOR SURFACE TREATMENT OF SUBSTRATE AND METHOD FOR FORMING FINE PATTERNS USING THE SAME

摘要

A silicone-based adhesive composition, a method for treating the surface of a substrate by using the composition for forming a circuit wiring, a method forming a micropattern by using the surface-treated substrate, and a circuit board containing the micropattern are provided to improve the adhesion of wiring and the spreading of an ink and to lower the surface energy of a substrate. A silicone-based adhesive composition comprises 55-65 parts by weight of a vinyl polysiloxane-based silicone polymer; 30-45 parts by weight of a polydimethyl siloxane-based silicone adhesive; 4-8 parts by weight of a hydrogen polysiloxane-based resin; and 0.1-2 parts by weight of a platinum catalyst. Preferably the vinyl polysiloxane-based silicone polymer is represented by the formula 1 (wherein n is an integer of 100-1,000); and the polydimethyl siloxane-based silicone adhesive is represented by the formula 2 (wherein n is an integer of 5,000-140,000).
