    摘要： 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 15×104 dynes/cm2 at 10 rad/s. (25° C.), a G″ (loss modulus) of 1 to 6×104 dynes/cm2, 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.

    摘要： Disclosed is a process of manufacturing a water-based adhesive bonded, solvent resistant protective laminate utilizing the steps of: providing a film having a first surface and a second surface; depositing a discontinuous coating of a cross-linkable; carboxylated styrene-butadiene rubber latex adhesive on the first surface of the film, the latex adhesive containing an effective amount of a cross-linking agent; joining a fibrous nonwoven web into intimate bonding contact with the film and adhesive; and removing water from the adhesive thereby causing cross-linking at reactive sites. The adhesive may be deposited utilizing gravure printing techniques and is desirably deposited at a rate greater than about 2 grams per square meter of film. Also disclosed is an adhesively bonded, solvent resistant protective laminate produced by the process. The film component of the laminate may be composed of a thermoset polymer or a thermoplastic polymer. The film may also be microporous or microapertured. The nonwoven fibrous web component may be selected from bonded carded webs, spunbonded webs, webs of meltblown fibers, multi-ply fibrous webs containing the same type of fibrous web, and multi-ply fibrous webs containing different types of fibrous webs.
