本発明の吸収性物品は、典型的には単回使用のための、使い捨て吸収性物品であってよい。本明細書で好ましい吸収性物品としては、生理用ナプキン、パンティライナー、成人用失禁パッド又はおむつ、プルオンパンツ又はトレーニングパンツを含む乳児又は幼児用おむつを挙げることができる。
本明細書の1つの実施形態では、本明細書の物品は、本明細書に記載するようなインク組成物を含む少なくとも1つのカフを含む。前記カフは、レッグカフ、バリアカフ並びに/又は肛門及び/若しくは生殖器カフであってよい。
本明細書のインク組成物は、水性組成物として適用される。発明者らは、驚くべきことに、このようなインク組成物を、これらの材料の極めて疎水性である、バリア性質にもかかわらず、本明細書に記載するように、高バリア不織布及び/又は極めて疎水性である不織布に適用できることを見出した。
本明細書のインク組成物を、任意の既知の方法により、本明細書のカフのシート材料に適用してよい。インク組成物は、カフの表面全体又はその一部上に適用してよい。インクを連続的に又は断続的に適用してもよい。
静水頭(水頭)
本明細書で使用するとき、静水頭(水頭とも呼ばれる)は、低表面張力液体、すなわち49mN/mの液体(溶液)を用いて測定される。
10Lの栓付き容器を2Lのポリエチレンで3回、次いで2Lの蒸留/脱イオン水で3回、完全に洗浄する。
インク組成物の表面張力及び表面張力低下剤を前記剤を含まないインク組成物に添加したときのその低下は、クリュス(Kruss)K12張力計を用いて、方法:ASTM D1331−56(「表面活性剤の溶液の表面及び界面張力のための標準的な試験方法」)により測定してよい。
本明細書のインク組成物を含むシート材料又はカフの摩擦係数を測定するために、本明細書では以下の方法を用いる。
(より多くのサンプルを取ることができる場合、試験を繰り返してよく、ΔE値について本明細書で記載するように、平均ΔEを算出することができる)。
本明細書で言及するとき光学密度は、本明細書に記載するようなインク組成物を有するシート材料のサンプルを、白色ボール紙(すなわち、PG2000、サンケミカルズ(Sun Chemicals)(米国、ノースカロライナ州、シャーロット(Charlotte))上に置かれた、分光光度計の下の中央に置くことにより、例えばグレタ・マクベス・スペクトロ・アイ・反射分光光度計(Gretag Macbeth Specro Eye reflectance spectrophotometer)を用いて、標準的なCIELab色及び密度法を介して測定することができる。(設定:2°観察者角、フィルタ無し、ANSI T密度標準)。(対照基準方法:ASTM E 1331−96、「半球形形状を用いる分光測光法による反射要因及び色のための標準試験方法(Standard Test Method for Reflectance Factor and Color by Spectrophotometry Using Hemispherical Geometry)」)。
本明細書で言及するとき、材料の表面エネルギーは、当該技術分野において既知であるウォッシュバート試験(Washburt test)を介して測定され、例えばアウグスティヌス・サイエンティフィック社(AUGUSTINE SCIENTIFIC, LLC)(米国オハイオ州ニューベリ(Newbury))により実施される(49mN/mの低表面張力液体を用いる場合、それは上記静水頭試験で記載したように調製してよい)。
