Production of Copolymer Solution (A); S-1
[0136]230 g of xylene was charged to a 1,000 ml flask equipped with a thermometer, a reflux condenser, a stirrer, and a dropping funnel, after which a mixture of 230 g of triisopropylsilyl methacrylate, 210 g of methoxyethyl methacrylate, 30 g of methyl methacrylate, 30 g of ethyl acrylate, and 4 g of t-butyl peroxy-2-ethyl hexanoate (initially added) was added dropwise into the flask over a period of 1 hour, while stirring at 100±2 deg. C. in a nitrogen atmosphere. After the dropwise addition, the polymerization reaction was performed for 2 hours at 100±2 deg. C. Then, while stirring the resulting reaction solution at 100±2 deg. C., 1 g of t-butyl peroxy-2-ethyl hexanoate (subsequently added) was added three times with 2-hour intervals to perform the polymerization reaction. After that, 270 g of xylene (additional solvent) was added and dissolved, thus producing the triorganosilyl ester-containing copolymer solution S-1. Table 1 shows the vi...

Production of Copolymer Solutions S-2 to 6 and Comparative Copolymer Solutions H-1 to 4
[0137]Polymerization reactions were performed according to the same procedure as Production Example 1, using the organic solvent, monomers, and polymerization initiator shown in Table 1, thus producing the triorganosilyl ester-containing copolymer solutions S-2 to 6, and the comparative copolymer solutions H-1 to 4. Table 1 shows the viscosity, non-volatile content, Mw, and Tg of each copolymer solution obtained.

Production of Gum Rosin Copper Salt
[0138]400 g of a xylene solution of gum rosin (solid content: 50%); 200 g of cuprous oxide, and 100 g of methanol were added, together with glass beads (diameter: 2.5 to 3.5 mm), to a 1,000 ml flask equipped with a thermometer, a reflux condenser, and a stirrer, and the mixture was stirred for 8 hours at 70 to 80 deg. C. and then maintained for 2 days at 50 deg. C. The resulting mixture was cooled to room temperature (25 deg. C.) and filtered, and subsequently concentrated under reduced pressure to remove the methanol by distillation. Xylene was then added to the obtained concentrate, thus producing a xylene solution of gum rosin copper salt (a transparent dark blue solution; solid content: about 50%). The resulting xylene solution of gum rosin copper salt had a non-volatile content of 50.8%.
