Title (EN) LASER MARKING INK COMPOSITION
(FR) COMPOSITION D’ENCRE DE MARQUAGE LASER
(JA) レーザーマーキング用インキ組成物
Abstract:
(EN) The purpose of the present invention is to provide: a laser marking ink composition that can be applied to packaging materials, particularly food packaging materials, and that exhibits jet-blackness, durability, and visibility due to a high printing density; and a recording agent obtained using the ink composition. A laser marking ink composition containing a polyurethane resin (A) having a weight-average molecular weight of 15,000-100,000 and an infrared laser coloring pigment (B), wherein the laser marking ink composition is characterized in that the content ration between the polyurethane resin (A) and the infrared laser coloring pigment (B) is 1:2.6 to 1:5 in terms of the (A):(B) mass ratio.
(FR) La présente invention concerne : une composition d’encre de marquage laser qui peut être appliquée aux matériaux d’emballage, particulièrement aux matériaux d’emballage alimentaire, et qui fait preuve d’une noirceur de jais, de durabilité, et d’une visibilité due à la densité d’impression élevée ; et un agent d’enregistrement obtenu en utilisant la composition d’encre. Une composition d’encre de marquage laser contenant une résine de polyuréthane (A) présentant un poids moléculaire moyen en poids de 15 000 à 100 000 et un pigment de coloration laser infrarouge (B), la composition d’encre de marquage laser étant caractérisée en ce que le rapport des contenus entre la résine de polyuréthane (A) et le pigment de coloration laser infrarouge (B) est de 1:2,6 à 1:5 en termes de rapport en masse (A):(B).
(JA) 本発明は、包装材、特に食品包装材に適用できる、高い印字濃度による視認性、耐久性、及び漆黒性を兼備したレーザーマーキング用インキ組成物、及び当該インキ組成物に用いて得られる記録剤を提供することを目的とする。 重量平均分子量が15,000~100,000であるポリウレタン樹脂(A)と赤外線レーザー発色顔料(B)を含有するレーザーマーキング用インキ組成物であって、前記ポリウレタン樹脂(A)と前記赤外線レーザー発色顔料(B)の含有比率が質量比で(A):(B)=1:2.6~1:5であることを特徴とするレーザーマーキング用インキ組成物。
