Abstract
A disposable diaper is disclosed having reduced bulk, especially in the back waist region. Due to an opaque topsheet and a backsheet having a relatively high percentage of printed surface area, the diaper has reduced see-through even in those areas of the back waist region where no absorbent core is comprised.

A disposable diaper comprising a chassis, the chassis comprising a topsheet and a backsheet, the disposable diaper further comprising an absorbent core disposed between the topsheet and backsheet,
- wherein the chassis has a longitudinal dimension and a chassis back waist region, a chassis back waist edge, a chassis front waist region and a chassis crotch region, the chassis back waist region making up about 25% of the longitudinal dimension of the chassis beginning at the chassis back waist edge and extending towards the chassis crotch region,
- wherein the absorbent core has a longitudinal dimension co-extending with the longitudinal dimension of the chassis, the absorbent core having an absorbent core back waist region, an absorbent core front waist region and an absorbent core crotch region, wherein the absorbent core further has an absorbent core back waist edge, the absorbent core back waist edge being longitudinally offset by at least 10 percent from the chassis back waist edge, the 10% offset being based on the longitudinal dimension of the chassis;
- wherein the absorbent core back waist region makes up about 25% of the longitudinal dimension of the absorbent core region and comprises about 0.01 g/cm2 or less of absorbent material;
- wherein the absorbent core front waist region makes up about 25% of the longitudinal dimension of the absorbent core region and comprises about 0.03 g/cm2 or more of absorbent material;
