Title: (DE) VERGLASUNG
(EN) GLAZING
(FR) VITRAGE
Abstract: front page image
(EN) A laminated glazing comprising two plies of glass having an interlayer structure laminated therebetween is disclosed. The interlayer structure comprises a first sheet of an interlayer material framing a suspended particle device film incorporated therein. The interlayer material is chosen to minimise the migration of the components of the interlayer material into the suspended particle device film. Preferably, the interlayer material does not contain plasticizers, or contains a plasticizer which does not diffuse into the suspended particle device film structure.
(FR) La présente invention concerne un vitrage feuilleté qui comprend deux couches de verre pourvues d'une structure intercalaire feuilletée entre les couches. La structure intercalaire comprend une première feuille en matériau intercalaire encadrant un film pour dispositif à particules en suspension incorporé dans la feuille. Le matériau intercalaire est choisi en vue de minimiser la migration des composants du matériau intercalaire dans le film pour dispositif à particules en suspension. Idéalement, le matériau intercalaire ne contient pas de plastifiants ou alors renferme un plastifiant qui ne se diffuse pas dans le film pour dispositif à particules en suspension.
