Abstract
A top sheet includes a skin contact surface configured to contact the skin of a wearer. The skin contact surface includes at least one projection and at least one recess. The top sheet further includes a back surface opposite the skin contact surface. The top sheet further includes a coating on the at least one projection. The coating essentially includes a blood slipping agent having a kinematic viscosity of 0.01 to 80 mm2/s at 40° C., a water holding percentage of 0.01 to 4.0 mass %, and a weight-average molecular weight of less than 1,000, and the coating is configured to slip from the skin contact surface, through the top sheet, to the back surface along with menstrual blood.

A top sheet comprising:
- a skin contact surface configured to contact the skin of a wearer, wherein the skin contact surface comprises at least one projection and at least one recess;
- a back surface opposite the skin contact surface;
- and
- a coating on the at least one projection, wherein the coating consists essentially of a blood slipping agent having a kinematic viscosity of 0.01 to 80 mm2/s at 40° C., a water holding percentage of 0.01 to 4.0 mass %, and a weight-average molecular weight of less than 1,000, and the coating is configured to slip from the skin contact surface, through the top sheet, to the back surface along with menstrual blood.
