Abstract

Un film de liaison selon un mode de réalisation comprend au moins une couche de liaison qui comprend une résine de polyvinyleacétal, un plastifiant et un régulateur de force de liaison, le régulateur de force de liaison étant un film comprenant un complexe métallique à base d'hydroxytoluène butylé. Lorsqu'elle est ajoutée, même une petite quantité du régulateur de force de liaison peut atteindre un effet de régulation de la force de liaison à un niveau prédéterminé ou plus. La durabilité et la résistance à l'humidité du film de liaison peuvent être améliorées par l'introduction d'une petite quantité du régulateur de force de liaison.
