Abstract
(EN)
The present invention provides: an intermediate laminate which is suitable for use in laminates such as laminated glass, can impart various functions in a simple manner, has a high design degree-of-freedom of the functions to be imparted, and has good transmission visibility; and a laminate using the intermediate laminate. An intermediate laminate (5A) according to the present invention comprises a first adhesive layer (11) and a first crosslinked cured resin layer (12) which are directly laminated without any other layers therebetween, wherein the first adhesive layer (11) contains a polyvinyl acetal resin and/or an ionomer resin. The first crosslinked cured resin layer (12) may have a fine concavo-convex pattern on the surface on the reverse side from the first adhesive layer (11) side. A laminate (6A) comprises the intermediate laminate (5A) and a pair of translucent substrates (21, 22) sandwiching the intermediate laminate (5A).

La présente invention concerne : un stratifié intermédiaire, lequel stratifié est approprié pour être utilisé dans des stratifiés tels que du verre feuilleté, lequel peut conférer différentes fonctions d'une manière simple, lequel a un degré de liberté de conception élevé des fonctions devant être conférées, et lequel a une bonne visibilité de transmission ; et un stratifié utilisant le stratifié intermédiaire. Un stratifié intermédiaire (5A) selon la présente invention comprend une première couche adhésive (11) et une première couche de résine durcie réticulée (12) qui sont directement stratifiées sans aucune autre couche entre elles, la première couche adhésive (11) contenant une résine d'acétal polyvinylique et/ou une résine ionomère. La première couche de résine durcie réticulée (12) peut avoir un fin motif concavo-convexe sur la surface sur le côté inverse du côté de la première couche adhésive (11). Un stratifié (6A) comprend le stratifié intermédiaire (5A) et une paire de substrats translucides (21, 22) prenant en sandwich le stratifié intermédiaire (5A).
