◎: Whole is transparent ○: Partially cloudy △: Whole is cloudy white x: Whole is cloudy Existence of peeling (adhesion)
A: No peeling (no peeling even when rubbed with a finger)
○: No peeling (peeling when rubbed with a finger)
Δ: Partially peeled ×: Whole peeled

Here, it is considered that the reason why white turbidity is less likely is that, due to the fact that the average particle diameter is small and the particles are gathered at a high density, it is difficult for water to penetrate between the particles. It is done. Also, the reason why it became difficult to peel off is that various factors seem to be combined, but one reason is that the adhesion of the resin to the glass plate has been improved due to the difficulty of water penetration. it is conceivable that.

  Further, from the results shown in Example 14, the resin polymerized using an ionic liquid further having a reactive group at the cation site forms a strong film by reacting with the reactive group, resulting in physical impact. It is thought that even if it added, it became difficult to peel.

The glossiness was measured. The gloss retention was defined as the percentage of gloss / initial gloss after natural exposure of each test piece. Table 5 shows the measurement results.

  It was found that the test piece containing an ionic liquid having a sulfonic acid group at the anion site suppresses a decrease in gloss retention.

  As mentioned above, it turned out that the test piece obtained using the processing agent containing the ionic liquid which has a sulfonic acid group in an anion site is excellent in a weather resistance.
