Document Type and Number:
WIPO Patent Application WO/2014/050414
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an absorbent article that is provided with a liquid-permeable layer, said liquid-permeable layer having convex portions that are hollow inside, has an improved ability to transfer menstrual blood from the liquid-permeable layer to an absorbent body and can reduce the amount of the menstrual blood remaining in the liquid-permeable layer (in particular, the internal cavities in the convex portions). To solve this problem, provided is a sanitary napkin (1) provided with a liquid-permeable top sheet (2), a liquid-impermeable back sheet (3) and an absorbent body (4) that is interposed between the top sheet (2) and the back sheet (3), wherein convex portions (8), said convex portions being hollow inside and formed in an excretion orifice contact region of the top sheet (2), are coated with a blood lubricity-imparting agent that has a kinetic viscosity of 0.01-80 mm2/s at 40°C, a water retention rate of 0.01-4.0 mass% and a weight-average molecular weight of less than 1,000.
