Title
(EN) GAS-BARRIER LAMINATE
(FR) STRATIFIÉ FAISANT BARRIÈRE AUX GAZ
(JA) ガスバリア性積層体
Abstract
(EN)
A gas-barrier laminate having a layered structure which comprises a curable adhesive layer, a gas-barrier film, and a protective film which have been disposed in this order. In cases when the gas-barrier laminate is applied to a glass plate by pressing the gas-barrier laminate against the glass plate, using the surface of the curable adhesive layer as a bonding surface, with a roller under the following conditions (α) and then peeled off under the following conditions (β) and under other conditions according to JIS Z0237:2000 to measure the adhesive force a between the glass plate and the curable adhesive layer and the adhesive force b between the gas-barrier film and the protective film, then the adhesive forces a and b satisfy relationship (1). (1): a>b Conditions (α): Temperature, 23°C; pressure, 0.2 MPa; and speed, 0.2 m/min Conditions (β): After the application, the laminate on the glass plate is allowed to stand still for 24 hours in an environment of 23°C and a relative humidity of 50% and then peeled off at a peel speed of 300 mm/min.
(FR)
L'invention concerne un stratifié faisant barrière aux gaz ayant une structure en couches qui comprend une couche adhésive durcissable, un film faisant barrière aux gaz, et un film protecteur qui ont été disposés dans cet ordre. Dans les cas où le stratifié faisant barrière aux gaz est appliqué à une plaque de verre par pression du stratifié faisant barrière aux gaz contre la plaque de verre, à l'aide de la surface de la couche adhésive durcissable en tant que surface de liaison, avec un rouleau dans les conditions suivantes (alpha) puis décollée dans les conditions suivantes (beta) et dans d'autres conditions selon la Norme JIS Z0237: 2000 pour mesurer la force adhésive a entre la plaque de verre et la couche adhésive durcissable et la force adhésive b entre le film faisant barrière aux gaz et le film protecteur, alors les forces adhésives a et b satisfont la relation (1). (1) : a>b Conditions (alpha): température, 23 °C; pression, 0,2 MPa; et vitesse, 0,2 m/Min Conditions (beta) : après l'application, le stratifié sur la plaque de verre est laissé à reposer pendant 24 heures dans un environnement à 23 °C et avec une humidité relative de 50 % puis décollé à une vitesse de pelage de 300 mm/min.
