Laminates with structured layers

Abstract

An article including at least one first layer with a first major surface and a second major surface, wherein at least one of the first and second major surfaces is a structured surface; and a cap layer in contact with a structured surface of the first layer.

What is claimed is: 
     
         1 . A method for making a prelaminate, comprising: (a) applying an adhesive to a structured surface of a tool to form an adhesive layer with a structured surface and a non-structured surface; (b) laminating a backing to the non-structured surface of the adhesive layer to form a prelaminate; and (c) removing the prelaminate from the tool. 
     
     
         2 . The method of  claim 1 , further comprising laminating a cap layer to the structured surface of the prelaminate. 
     
     
         3 . The method of  claim 1 , wherein the cap layer is an adhesive layer. 
     
     
         4 . The method of  claim 3 , wherein the adhesive layer is a structured adhesive layer. 
     
     
         5 . The method of  claim 1 , wherein the cap layer is a backing. 
     
     
         6 . The method of  claim 5 , wherein the backing is structured. 
     
     
         7 . The method of  claim 1 , further comprising laminating a cap layer to the structured surface of the prelaminate. 
     
     
         8 . The method of  claim 7 , further comprising removing the backing from the non-structured surface of the prelaminate. 
     
     
         9 . A method for making a laminate, comprising: (a) providing a first prelaminate comprising a first adhesive layer with a structured first major surface and a non-structured second major surface, and a cap layer contacting the first major surface of the first prelaminate; and (b) providing a second prelaminate comprising a second adhesive layer with a structured first major surface and a non-structured second major surface, and a backing contacting the second major surface of the second prelaminate; and (c) contacting the second major surface of the first prelaminate to the first major surface of the second prelaminate. 
     
     
         10 . The method of  claim 9 , further comprising filling a region between the first adhesive layer and the second adhesive layer with at least one a deliverable and a non-deliverable substance. 
     
     
         11 . The method of  claim 10 , wherein the region is filled by coating. 
     
     
         12 . The method of  claim 10 , wherein the region is filled under a vacuum. 
     
     
         13 . A method for making a laminate, comprising: (a) providing a first prelaminate comprising a first adhesive layer with a structured first major surface and a non-structured second major surface, and a first backing layer contacting the second major surface of the first prelaminate; (b) providing a second prelaminate comprising a second adhesive layer with a structured first major surface and a non-structured second major surface, and a second backing layer contacting the second major surface of the second prelaminate; and (c) contacting the first major surface of the first prelaminate with the first major surface of the second prelaminate. 
     
     
         14 . The method of  claim 13 , further comprising filling a region between the first adhesive layer and the second adhesive layer with at least one a deliverable and a non-deliverable substance. 
     
     
         15 . The method of  claim 14 , wherein the region is filled by coating. 
     
     
         16 . The method of  claim 15 , wherein the region is filled under a vacuum. A method for making a laminate, comprising: (a) providing a first prelaminate comprising a structured first major surface and a non-structured second major surface; (b) providing a second prelaminate comprising a first structured major surface and a second non-structured major surface, and a backing layer contacting the second major surface of the second prelaminate; and (c) contacting the second major surface of the first prelaminate with the first major surface of the second prelaminate. 
     
     
         17 . The method of  claim 13 , wherein the first prelaminate is formed by casting an adhesive on a tool. 
     
     
         18 . An article comprising at least one first layer with a first major surface and a second major surface, wherein at least one of the first and second major surfaces is a structured surface; and a cap layer in contact with a structured surface of the first layer, wherein the cap layer comprises an adhesive. 
     
     
         19 . The article of  claim 18 , wherein the cap layer is non-structured. 
     
     
         20 . The article of  claim 18 , wherein the first layer comprises a polymeric film.
