Patent ID: 8067063

Claim:
A process for making a stretch composite comprising the steps of: a. providing at least one inelastic substrate; b. applying a tensioning force to the inelastic substrate to form a necked, inelastic substrate; c. providing an application device, said device including at least one patterned print roll; and d. printing at least two differing elastomeric members by means of said patterned print roll, onto said substrate to form a stretch composite, said elastomeric members differing in a property selected from the group consisting of differing width dimensions between said elastomeric members, differing mechanical properties between said elastomeric members, differing elastomeric compositions between said elastomeric members and differing visual appearance between said elastomeric members, and wherein said elastomeric members comprise a thermoplastic elastomer and a phase change solvent having the general formula: R′-L y -(Q-L x ) n-1 -Q-L y -R; (I) R′-L y -(Q-L x ) n -R; (II) R′-(Q-L x ) n -R; (III) R′-(Q-L x ) n-1 -Q-L y -R; (IV) R′-(Q-L x ) n-1 -Q-R; or (V) a mixture thereof; wherein Q is a para-ring substituted difunctional aromatic moiety, and wherein the substitutions are in the 1,4 positions; L is CH 2 ; R and R′ are the same or different and are independently selected from H, CH3, COOH, CONHR 1 , CONR 1 R 2 , NHR 3 , NR 3 R 4 , hydroxy, or C1-C30 alkoxy; wherein R 1 , R 2 , R 3 and R 4 are the same or different and are independently selected from H or linear or branched alkyl from C1-C30; x is an integer from 1 to 30; y is an integer from 1 to 30; and n is an integer from 3 to 7; wherein the phase change solvent has a phase change in a temperature range from 40° C. to about 250° C.
