Problems solved by technology

[0005] However, the inventors have found it difficult to print ink compositions on high barrier nonwovens, which have fiber surfaces with low affinity for ink; they have found it difficult to provide high quality permanent inks on nonwovens with high barrier properties. Permanent printing, the ink is friendly to the wearer, non-irritating and does not affect the performance of the nonwoven sheet material
Furthermore, this is even more difficult if these materials with ink compositions come into contact with bodily exudates such as blood and urine in use

Embodiment Construction

[0019] As used herein, "absorbent article" refers to any article that absorbs body fluids and is adapted to be placed next to the genitals and / or anus of the user (in particular including adult or baby diapers and so-called training pants or pull-on training pants, hygienic pads or napkins, panty liners, adult incontinence liners).

[0020] As used herein, the term "void space" refers to a cavity in or enclosed by an article in at least a relaxed state for receiving and containing bodily exudates, such as feces. For example, the cavity is at least 3 cm in a relaxed state 3 .

[0021] As used herein, "longitudinal" is a direction that runs substantially parallel to the largest linear dimension of a component, generally parallel to the longitudinal axis of an article, and where applicable includes directions within 30° of such parallel.

[0022] "Lateral" or "transverse" is orthogonal to the longitudinal direction and lies in the same plane as the majority of the article and t...

Abstract

The present invention relates to absorbent articles that comprise high barrier sheets that comprise an ink composition that is applied in aqueous form, free of organic solvents, and processes for making such articles. The sheets are typically used as or part of a cuff, such as an anal and / or genital cuff (also referred to as topsheet with opening or openings) or leg cuff or barrier cuff, used in for example diapers. The water-based ink comprises typically surfactant and a specific water-based film-forming polymer solution or dispersion.

Description

field of invention [0001] The present invention relates to absorbent articles comprising high barrier sheets comprising ink compositions applied in aqueous form and methods of making such articles. Background of the invention [0002] It has become common practice in the hygiene product industry to provide articles such as diapers and sanitary napkins with printed backsheets or diapers with printed waistband portions, in particular to improve the attractiveness of the articles. Alternately or additionally, such articles often include small printed marks required during the production process to align and phase the components of the article. There has also been recent interest in providing absorbent articles with printed information that facilitates application of the article. [0003] Some of these articles include hydrophobic components, such as leg cuffs or barrier cuffs, or more recently developed anal / genital cuffs, also known as topsheets with large openings, such as d...
