Abstract
A sanitary napkin having a body-side adhesive is disclosed having an absorbent core with at least one body-facing surface designed to be positioned against the wearer's body and a pressure sensitive adhesive secured to the body-facing surface. In one aspect, the article is limited in dimension and includes a hot melt adhesive to be pressed against the wearer's pudendal region and characterized by a midblock Tg of less than −10° C., a G′ (storage modulus) less than 15×10 dynes/cm at 10 rad/s. (25° C.), a G″ (loss modulus) of 1 to 6×10 dynes/cm , a tensile strength greater than 10 psi, and requiring no subsequent curing operation after cooling. In one aspect, the article includes the adhesive to be pressed against the wearer's pudendal region has an adhesive weight less than 1500 mg per square inch and a tan delta residing inside a quadrangle ABCD wherein said quadrangle ABCD is defined by graphically plotting frequency in radians per second versus tan delta referenced to about 20° Centigrade of the adhesive, the quadrangle ABCD having as points A and D a tan delta of about 0.01 and about 0.6 respectively at a frequency of about 0.1 radians per second and points B and C at a tan delta of about 0.1 and about 1.7 respectively at a frequency of about 1000 radians per second.
