Description of the Related Art Disposable sanitary materials such as diapers and sanitary napkins generally have a water-permeable top sheet which comes into direct contact with the skin, an absorbent body and a waterproof back sheet. Many of the backsheets that are the outer surface of disposable hygiene materials use a waterproof film, but in recent years, they have a soft feel due to the fact that they feel stiff when they are put on and taken off or during use. Therefore, improvements have been made such as improving the feel of the film surface and bonding the film and the non-woven fabric.

When pasted, the printed surface will see through the non-woven fabric, so
There was a problem that even in dark color printing, it lacked in sharpness and became blurry.
