Therefore, when the resin surface roughening composition containing the aliphatic polycarbonate is completely decomposed, as can be seen from the result of Example 13 (FIG. 2), the portion becomes a void, and many convex signals are seen downward. On the other hand, in Comparative Example 7, the surface was roughened compared to Comparative Example 6 in which nothing was added, but there were many upwardly convex signals, indicating that the aliphatic polycarbonate remained undecomposed. (Fig. 2).
- Example 14 Surface Treatment of Epoxy Resin 1 g of the resin composition obtained in Example 1 was added to 6.75 g of 3 ′, 4′-epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate (Delcel Celoxide 2021P). Added and stirred. Insoluble matter was removed, and 2.25 g of acid anhydride (Ricacid MH-700 manufactured by Shin Nippon Chemical Co., Ltd.) was added and stirred for 2 hours. Then, 0.3 g of triphenylphosphine was added, and the mixture was further stirred for 1 hour. The obtained solution was coated on a glass substrate with a bar coater, and then heated at 120 ° C.
- Example 8 A film was prepared in the same manner as in Example 14 except that the resin surface roughening composition obtained in Example 1 was not added, and the surface roughness was evaluated. The results are shown in FIG.
- Example 9 A film was prepared in the same manner as in Example 14 except that the polypropylene carbonate obtained in Production Example 2 was used instead of the resin surface roughening composition obtained in Example 1, and the surface roughness was evaluated. did. The results are shown in FIG.
