TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The composition preferably comprises (in weight%) binder resin (5-30), fine powder (50-90), glass frits (1-10) and solvent (4-30). Preferred Components: The composition further comprises additive(s) comprising dispersing agent, polymer stopper, antioxidant, antifoaming agent, leveling agent and/or thixotropic agent. The hydroxyl containing monomer is chosen from 2-hydroxyethyl (meth)acrylic acid, 2-hydroxypropyl (meth)acrylic acid and 3-hydroxypropyl (meth)acrylic acid. The carboxyl-containing monomer is chosen from acrylic acid, methacrylic acid, maleic acid, fumaric acid, crotonic acid, itaconic acid and citraconic acid. The acrylate type monomer is chosen from methyl (meth)acrylate, ethyl (meth)acrylate, n-butyl (meth)acrylic acid, n-lauryl (meth)acrylic acid, benzyl (meth)acrylic acid, glycidyl (meth)acrylate, isooctyl acrylate and isododecyl (meth)acrylate. The polyisocyanate is chosen from isophorone diisocyanate (IPDI), 2,4-toluene diisocyanate, 2,6-toluene diisocyanate (TDI), 4,4'-diphenylmethane diisocyanate (MDI), 2,4'-diphenylmethane diisocyanate, 4,4'-dicyclohexylmethane diisocyanate (MDI), para-tetramethyl xylene diisocyanate (TXMDI), and diisocyanate(s) containing hexamethylene diisocyanate (HDI).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The binder resin is formed from a polymer and polyisocyanate, where the polymer has one or more recurring units of formula: (-CH2-C(R1)(C(C=O)(OR2)-)n).R1=H or CH3;R2=1-15C saturated alkyl, H, OH, carboxyl, ether, carbonyl or ester;andn=1-1000.Preferred Process: The polymer is obtained by polymerizing one or more monomers chosen from hydroxyl containing monomer, carboxyl containing monomer, acrylate type monomer, polystyrene, poly(methyl)methacrylate and poly(meth)acrylic acid ester monomer. Preferred Properties: The content of the polymer is 10-80 weight% of the paste composition. The weight ratio of the polyisocyanate and the polymer in the binder resin is 100:1-5. The binder resin has an average molecular weight of 1000-100000. The solvent has a boiling point of 150-300 degrees C. EXAMPLE - 2-Hydroxyethyl (meth)acrylic acid (10 weight%) and n-butyl (meth)acrylic acid (15 weight%) were reacted in presence of 2,2-azobis isobutyronitrile (AIBN) (2 weight%.) as initiator and butylcarbitol acetate (4 weight%) as solvent, to form a polymer. The obtained polymer was mixed with isophorone diisocyanate (1 weight%) to form a binder resin. The binder resin (15 weight %) was mixed with glass frits (3 weight %), an additive comprising a dispersing agent, an antioxidant (EFKA 4300 CIBA chemistry) and an antifoaming agent (AC-300 KYOEISHA chemistry) (3 weight %) and butylcarbitol acetate as solvent (4 weight %) in a mixer and dissolved by mixing. The obtained mixture was added to a conductive fine powder (75 weight%) and mechanically mixed using a three-roll mill. Impurities were filtered to obtain a conductive paste composition. The composition when used in an offset printer ensured good pattern formation.
