Title
(EN) LAMINATE AND PROCESSING PAPER
(FR) STRATIFIÉ ET PAPIER DE TRAITEMENT
(JA) 積層体及び工程紙
Abstract
(EN)
Provided are a laminate and a processing paper, wherein sufficient adhesion between a base paper and a release layer can be achieved even when the base paper used is a smooth base paper, and the adhesion can be maintained even at high temperatures. The laminate comprises a laminated structure in which a base paper 11, an adhesion-enhancing layer (A) 12, and a polypropylene-based resin layer (B) 13 are disposed in this order, wherein the base paper 11 has an Oken-type smoothness of at least 100 seconds on at least a surface facing the adhesion-enhancing layer (A) 12, the adhesion-enhancing layer (A) 12 contains a polyvinyl alcohol (P) and a silica particle (S) derived from a necklace-like colloidal silica, and the mass content ratio (S/P) of the silica particle (S) to the polyvinyl alcohol (P) is 20/5-20/30.

L'invention concerne un stratifié et un papier de traitement, une adhérence suffisante entre un papier de base et une couche antiadhésive pouvant être obtenue même lorsque le papier de base utilisé est un papier de base lisse, et l'adhérence pouvant être conservée même à des températures élevées. Le stratifié comprend une structure stratifiée dans laquelle un papier de base (11), une couche d'amélioration d'adhérence (A) (12), et une couche de résine à base de polypropylène (B) (13) sont disposés dans cet ordre, le papier de base (11) ayant un lissé de type Oken d'au moins 100 secondes sur au moins une surface faisant face à la couche d'amélioration d'adhérence (A) (12), la couche d'amélioration d'adhérence (A) (12) contenant un alcool polyvinylique (P) et une particule de silice (S) dérivée d'une silice colloïdale de type collier, et le rapport de teneur en masse (S/P) entre la particule de silice (S) et l'alcool polyvinylique (P) étant de 20/5 à 20/30.
