Title (EN) BIODEGRADABLE ACID-MODIFIED POLYESTER-BASED RESIN, AND LAMINATE
(FR) RÉSINE À BASE DE POLYESTER MODIFIÉE PAR UN ACIDE BIODÉGRADABLE, ET STRATIFIÉ
(JA) 生分解性酸変性ポリエステル系樹脂及び積層体
Abstract:
(EN) The purpose of the present invention is to provide a biodegradable acid-modified polyester-based resin with which it is possible to obtain a laminate containing a polyvinyl-alcohol-based resin layer and a biodegradable resin layer, the laminate having little roughness at an adhesive layer interface between the two layers, and having both exceptional adhesiveness and an exceptional external appearance. The present invention pertains to a biodegradable acid-modified polyester-based resin having an acid value of 2.0-6.5 mg KOH/g.
(FR) La présente invention vise à produire une résine à base de polyester modifiée par un acide biodégradable permettant d'obtenir un stratifié contenant une couche de résine à base d'alcool polyvinylique et une couche de résine biodégradable, le stratifié présentant une faible rugosité au niveau d'une interface de couche adhésive entre les deux couches, et présentant une adhésivité exceptionnelle et un aspect externe exceptionnel. La présente invention concerne donc une résine à base de polyester modifiée par un acide biodégradable ayant un indice d'acide de 2,0 à 6,5 mg KOH/g.
(JA) 本発明は、ポリビニルアルコール系樹脂層と生分解性樹脂層を含有する積層体であって、両層の接着層界面での荒れが少なく、外観性及び接着性の両方に優れる積層体を得ることができる生分解性酸変性ポリエステル系樹脂を提供することを目的とする。本発明は、酸価が2.0~6.5mg・KOH/gである、生分解性酸変性ポリエステル系樹脂に関する。
