[0040] The present invention relates to absorbent articles, such as feminine hygiene napkins, having improved stain resistance properties. More specifically, the sanitary napkins of the present invention are capable of minimizing the "red" appearance of menstrual fluid after the sanitary napkin absorbs fluid, while providing a shiny overall appearance to the sanitary napkin prior to dyeing.

[0041] Color measurements provided here are made using CIE La * b * color system. La * b * The color system, also known as Hunter Scale, is well known to those skilled in the art. La * b * The system is related to the eye's sensitivity to brightness, or luminosity, and to color changes. The L value reflects the sensitivity of the eye to lightness when observing a color change from dark to light and from gray to white.
