Abstract
(EN)
This organic solvent-based printing ink is used to form a separation layer for recycling a base material 1 by separating a pattern layer and/or base material 2 from printed material or a laminate body which comprises, in order, the base material 1, the separation layer, and the pattern layer and/or base material 2, wherein the organic solvent-based printing ink contains a polyurethane resin with an acid value of 15-70 mgKOH/g as a binder resin.
(FR)
L'invention concerne une encre d'impression à base de solvant organique utilisée pour former une couche de séparation pour recycler un matériau de base 1 par la séparation d'une couche de motif et/ou d'un matériau de base 2 à partir d'un matériau imprimé ou d'un corps stratifié qui comprend, dans l'ordre, le matériau de base 1, la couche de séparation et la couche de motif et/ou le matériau de base 2, l'encre d'impression à base de solvant organique contenant une résine de polyuréthane présentant un indice d'acide de 15 à 70 mg de KOH/g en tant que résine liante.
(JA)
基材1、脱離層、並びに、絵柄層および/または基材2をこの順に有する印刷物ないし積層体から、絵柄層および/または基材2を剥離させて、基材1をリサイクルするための脱離層を形成することに用いられる有機溶剤系印刷インキであって、 有機溶剤系印刷インキは、バインダー樹脂として、酸価15~70mgKOH/gであるポリウレタン樹脂を含有する、有機溶剤系印刷インキ。
