TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The paste composition further comprises a conductive material, where the conductive material contains at least one carbon black, graphite, carbon nanotube, carbon fiber, gold and silver. Preferred Components: The ratio of the compound is not less than 0.1 parts by weight and not greater than 10-100 parts by weight of the whole of the compound, resin material, and conductive material. The resin material contains at least one of thermosetting resin and ultraviolet curing resin. Preferred Definitions:    R1 = H, carboxyl or methyl; and    R2 = H.    EXAMPLE - Dimethyl terephthalate (75 parts by weight), dimethyl isophthalate (40 parts by weight), ethylene glycol (80 parts by weight), neopentyl glycol (60 parts by weight), and tetrabutyl titanate (0.1 parts by weight) were prepared in four-necked flask, and ester exchange reaction was promoted at 180 degrees C for three hours, trimellitic anhydride (2 parts by weight) and sebacic acid (80 parts by weight) were then added, and dehydration reaction was promoted for one hour. The four-necked flask was then gradually depressurized to less than or equal to 1 mm Hg, and polymerization reaction was promoted at 270 degrees C for two hours, to obtain polyester resin. The obtained polyester resin (40 parts by weight) and diethylene glycol monoethyl ether acetate (100 parts by weight) were then prepared in the four-necked flask, were dissolved at 80 degrees C, and were cooled to a normal temperature. Then block member of hexamethylene diisocyanate (5 parts by weight) was prepared in the four-necked flask, to obtain binder resin (a resin material). Conductive carbon black (10 parts by weight), graphite (45 parts by weight), and binder resin (45 parts by weight) were then mixed, and their mixture was then dispersed using a triple roll kneader, to obtain a solution containing a resin material and a conductive material, then 1H-benzotriazole (1.5 parts by weight) was added to the solution, to obtain the paste composition.
