Embodiment 1

[0210] Under a dry nitrogen stream, 10.6 g (0.04 mol: 40 mol %) of o-toluene diisocyanate, 3.48 g (0.02 mol: 20 mol %) of 2,4-toluene diisocyanate, and 4,4' - 10.0 g (0.04 mol: 40 mol %) of diphenylmethane diisocyanate was dissolved in 120 g of N-methyl-2-pyrrolidone (NMP). To this, 19.2 g (0.1 mol: 100 mol %) of trimellitic anhydride and NMP 17.9 g were added as an acid component, reacted at 120° C. for 2 hours, and reacted at 140° C. for 2 hours to obtain a resin with a resin concentration of 20%. Composition 1.

Embodiment 2~9、14

[0211] Embodiment 2~9,14, comparative example 1 and 2

[0212] Compositions 2 to 9 and 14 to 16 having a resin concentration of 20% were obtained by the same method as in Example 1 using the amine components and acid components shown in Table 1.

Embodiment 10

[0214] Under a dry nitrogen stream, 18.5 g (0.07 mol: 70 mol %) of ortho-toluene diisocyanate and 5.22 g (0.03 mol: 30 mol %) of 2,4-toluene diisocyanate were dissolved in 120 g of NMP as amine components. To this, 0.871 g (0.01 mol: 10 mol %) of 2-butanone oxime and NMP 10 g were added as an end-capping agent, and reacted for 2 hours at 70° C., and further, 18.3 g (0.095 Mole: 95 mol%) and NMP8.12g were reacted at 120° C. for 2 hours and 140° C. for 2 hours to obtain a composition 10 with a resin concentration of 20%.

Description

technical field [0001] Resins, pastes, and conductive substrates, substrates with conductive wiring, suitable for use as lithium-ion secondary batteries, adhesives for capacitor electrodes, semiconductor packages, multilayer wiring boards, and insulating films for displays materials, their laminates, and methods for their manufacture. Background technique [0002] In recent years, with the explosive popularity of notebook personal computers and small portable terminals, the demand for rechargeable small, light-weight, high-capacity, high-energy-density, and high-reliability secondary batteries has increased. [0003] In addition, in the automotive industry, the reduction of carbon dioxide emissions through the introduction of electric vehicles (EV) and hybrid electric vehicles (HEV) is expected to be concentrated, and the development of secondary batteries for driving electrodes, which is the key to the practical use of these, is also eagerly pursued. . [0004] In particu...
