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.
