| 摘要 |
The solar cell sealant sheet of the present invention includes a coating film of a water-soluble thermosetting resin-dispersed paint obtained by emulsion-polymerizing a monomer mixture containing an ±,²-ethylenically unsaturated monomer having an alkoxysilyl group in a presence of a resin serving as a dispersant, the resin having a quaternized ammonium group that has been obtained by addition of a tertiary amine compound and an organic acid to having an epoxy group, wherein a hardness (B) in terms of a pencil hardness of the coating film after being thermally cured is 4B or higher, and a hardness ratio (B/A) of the hardness (B) after being thermally cured relative to a hardness (A) before being heated is 1.1 or higher. The sealant-integrated substrate of the present invention includes, as a sealant, the coating film of the water-soluble thermosetting resin-dispersed paint that is integrally layered on a surface on a solar cell element side of a substrate of a solar cell module. |
