  • Initial adhesion test The functional layer surfaces of the functional members prepared in the above-described examples and comparative examples were tested based on a cross-cut peel test defined by JIS K 5400, and evaluated according to the following criteria. “ ⁇ ” indicates that no more than a quarter of the 100 squares are peeled off, and “80” indicates that no more than a quarter of the 100 squares is peeled. “ ⁇ ” represents a state in which 100% of squares in which no more than a quarter of peeling was observed was less than 80 squares. The measurement results are shown in Table 3.
  • the functional members of Examples 1 to 11 have a solid content acid value of 10.0 mgKOH / g or more in the composition for forming an easy-adhesion layer on the substrate. Since the solid content acid value of the composition for forming the layer was 4.0 to 12.0 mg KOH / g, both the initial adhesion test and the adhesion test after exposure to high temperature and high humidity were evaluated well, and the substrate was easily adhered. The adhesion between the layers and the adhesion between the easy-adhesion layer and the functional layer were excellent.
  • Comparative Examples 2 and 5 the solid content acid value of the composition for forming the easy-adhesion layer is less than 10.0 mgKOH / g
  • Comparative Example 1 Comparative Example 3, and Comparative Example 4 are functional layers. Since the solid content acid value of the composition for forming an aqueous solution was less than 4.0 mgKOH / g or more than 12.0 mgKOH / g, the initial adhesion between the substrate and the easy-adhesion layer and / or the easy-adhesion layer and the functional layer and / or Or it was inferior to adhesiveness after high temperature, high humidity exposure.

Abstract

L'objectif de l'invention est d'améliorer l'adhérence entre un substrat et une couche hautement adhésive ainsi que l'adhérence entre la couche hautement adhésive et la couche fonctionnelle, et de maintenir une adhérence adéquate même après une exposition à long terme dans des environnements hostiles tels que des environnements à haute température et à humidité élevée. À cet effet, cet élément fonctionnel est obtenu en stratifiant, sur au moins un côté du substrat, la couche hautement adhésive et la couche fonctionnelle dans cet ordre, la valeur d'acide solide de la composition qui permet de former la couche hautement adhésive étant d'au moins 10,0 mg de KOH/g, et la valeur d'acide solide de la composition qui permet de former la couche fonctionnelle étant comprise dans la plage de 4,0 à 12,0 mg de KOH/g, inclus.
