A substrate has an elastomeric film having surfaces and a nonwoven web having fibers, wherein a plurality of fibers is partially embedded in one surface of the film. In addition, a substrate has an elastomeric film and a nonwoven web having fibers, wherein a plurality of fibers is partially embedded in one surface of the film, and wherein the substrate is essentially free of adhesives and film-based microfibers. A method for making a film/nonwoven composite includes providing an elastomeric film traveling in a machine direction; providing a nonwoven web traveling in the machine direction in face-to-face contact with the film, wherein the nonwoven web includes fibers; and impinging the elastomeric film with hydro jets such that at least some of the fibers become embedded in the film.

A triggerable composition for two-stage, controlled release of a functional active chemical includes a trigonelline ester of a functional active with at least one hydroxyl group configured to release the functional active through a hydrolysis reaction upon contact with an aqueous medium, and an encapsulation material for encapsulating the trigonelline ester including a functional active, the encapsulation material triggerable to release the trigonelline ester upon the occurrence of an environmental stimulus. In other aspects, a viscous liquid or an absorbent article includes a triggerable composition for two-stage, controlled release of a functional active chemical, the composition including a trigonelline ester of a functional active with at least one hydroxyl group configured to release the functional active through a hydrolysis reaction upon contact with an aqueous medium, and an encapsulation material for encapsulating the trigonelline ester including a functional active.
