Title (EN) WATER-DISPERSIBLE SHEET
(FR) FEUILLE DISPERSIBLE DANS L'EAU
(JA) 水分散性シート
Abstract:
(EN) [Problem] To provide a water-dispersible sheet which does not undergo the deterioration in the adhesiveness of an adhesive agent layer provided therein while retaining the water dispersibility thereof. [Solution] A water-dispersible sheet which comprises a paper-made base comprising an inside layer and at least one surface layer and an adhesive layer formed on one surface layer (also referred to as a "first surface layer", hereinbelow) of the paper-made base, wherein the first surface layer is made from mixed pulp 1 which is composed of wood pulp and purified pulp having an α-cellulose content of 88% by weight or more, the mixed pulp 1 has a Canadian Standard freeness of 450 to 600 mlCSF and contains the wood pulp at a content of 50 to 95% by weight, the inside layer is made from mixed pulp 3 which is composed of wood pulp and purified pulp having an α-cellulose content of 88% by weight or more, and the mixed pulp 3 has a Canadian Standard freeness of 600 to 750 mlCSF and contains the wood pulp at a content of 50 to 95% by weight.
(FR) Le problème décrit par la présente invention est de fournir une feuille dispersible dans l'eau qui ne subit pas de détérioration de l'adhésivité d'une couche d'agent adhésif disposée à l'intérieur de celle-ci tout en conservant sa dispersibilité dans l'eau. La solution selon l'invention porte sur une feuille dispersible dans l'eau qui comprend une base en papier comprenant une couche intérieure et au moins une couche de surface et une couche adhésive formée sur une couche de surface (également désignée « première couche de surface », ci-dessous) de la base en papier, la première couche de surface étant constituée de pâte mixte (1) qui est composée de pâte de bois et de pâte purifiée ayant une teneur en α-cellulose de 88 % en poids ou plus, la pâte mixte (1) a un indice d'égouttage Canadien Standard de 450 à 600 ml CSF et contient la pâte de bois à une teneur de 50 à 95 % en poids, la couche intérieure est constituée de pâte mixte (3) qui est composée de pâte de bois et de pâte purifiée ayant une teneur en α-cellulose de 88 % en poids ou plus et la pâte mixte (3) a un indice d'égouttage Standard Canadien de 600 à 750 ml CSF et contient la pâte de bois à une teneur de 50 à 95 % en poids.
(JA) 【課題】本願発明は、水分散性を保ちながら、粘着層の粘着性の経時劣化を抑えた水分散性シートを提供する。 【解決手段】内部層及び少なくとも一つの表面層から成る紙基材の一つの表面層(以下「第1の表面層」という。)上に粘着剤層を有する水分散性シートであって、該第1の表面層が、木材パルプ及びαセルロース含有率88重量%以上の精製パルプから成る混合パルプ1から成り、該混合パルプ1のカナダ標準ろ水度が450~600mlCSFであり、かつ該混合パルプ1中の該木材パルプの含有量が50~95重量%であり、該内部層が、木材パルプ及びαセルロース含有率88重量%以上の精製パルプから成る混合パルプ3から成り、該混合パルプ3のカナダ標準ろ水度が600~750mlCSFであり、かつ該混合パルプ3中の該木材パルプの含有量が50~95重量%である水分散性シート。
