Title (EN) RELEASE-PAPER BASE PAPER AND METHOD FOR PRODUCING SAME, AND RELEASE PAPER
(FR) PAPIER DE BASE DE PAPIER ANTIADHÉSIF ET SON PROCÉDÉ DE PRODUCTION, ET PAPIER ANTIADHÉSIF
(JA) 剥離紙原紙及びその製造方法、並びに剥離紙
Abstract:
(EN) A release-paper base paper obtained by coating a substrate with a coating agent which contains polyvinyl alcohol (A) and a compound (B), the release-paper base paper being characterized in that the compound (B) is an unsaturated carboxylic acid having a pKa of less than 4.00, or a derivative thereof, and the content of the compound (B) constitutes 0.1-20 parts by mass, inclusive, relative to 100 parts by mass of the polyvinyl alcohol (A). This release-paper base paper exhibits excellent silicone void filling characteristics and water resistance. In addition, the release-paper base paper can be used to accelerate the curing of the silicone in a release layer.
(FR) La présente invention concerne un papier de base de papier antiadhésif obtenu par revêtement d'un substrat avec un agent de revêtement qui contient de l'alcool polyvinylique (A) et un composé (B), le papier de base de papier antiadhésif étant caractérisé en ce que le composé (B) est un acide carboxylique insaturé ayant un pKa inférieur à 4,00, ou un dérivé de ce dernier, et la teneur du composé (B) constitue de 0,1 à 20 parties en masse, inclus, par rapport à 100 parties en masse de l'alcool polyvinylique (A). Ce papier de base de papier antiadhésif présente d'excellentes caractéristiques de remplissage de vides par silicone et une excellente résistance à l'eau. En outre, le papier de base de papier antiadhésif peut être utilisé pour accélérer le durcissement de la silicone dans une couche antiadhésive.
(JA) ポリビニルアルコール(A)と化合物(B)とを含むコーティング剤を基材に塗工してなる剥離紙原紙であって;化合物(B)が、pKa4.00未満の不飽和カルボン酸又はその誘導体であり、ポリビニルアルコール(A)100質量部に対して化合物(B)を0.1質量部以上20質量部以下含むことを特徴とする剥離紙原紙。本発明の剥離紙原紙は、シリコーンの目止め性及び耐水性に優れている。また、本発明の剥離紙原紙は、剥離層のシリコーンの硬化を促進させることができる。
