Abstract:
1. A process for making a stretch composite from an extensible substrate, said process comprising the steps of: a. providing a first extensible substrate; b. providing an application device, said device including at least one patterned print roll; c. printing one or more elastomeric compositions by means of said patterned print roll, said compositions having a melt viscosity of from about 1 to about 150 Pa·s, measured at 175° C. and 1 s d. incrementally stretching one or more portions of the intermediate structures to permanently elongate the substrate in the portions; and e. converting the elastomeric composition into elastomeric members forming one or more elasticized regions of the substrate; wherein said elastomeric composition comprises a thermoplastic elastomer and a phase change solvent having the general formula: wherein Q is a para-ring substituted difunctional aromatic moiety, wherein the substitutions are in the 1,4 positions; L is CH
