| description | The present invention is directed to a sealing layer that comprises a combination of polyurethane and poly(vinyl alcohol), the poly(vinyl alcohol) containing an acetoacetate functional group in its molecular structure. The sealing layer is formed from an aqueous sealing composition and shows water resistance and good barrier properties to non-polar fluids. The sealing layer can be used to seal microcells of electro-optic displays.
La présente invention concerne une couche d'étanchéité qui comprend une combinaison de polyuréthane et de poly(alcool vinylique), le poly(alcool vinylique) contenant un groupe fonctionnel acétoacétate dans sa structure moléculaire. La couche d'étanchéité est formée à partir d'une composition d'étanchéité aqueuse et présente une résistance à l'eau et de bonnes propriétés de barrière aux fluides non polaires. La couche d'étanchéité peut être utilisée pour sceller des microcellules d'affichages électro-optiques. |
