Abstract

A curable casemaking adhesive, books and related articles bound thereby. In one embodiment, a UV curable hot melt adhesive is used to form the case, which is preferably also embossed. In another embodiment, a moisture curable hot melt adhesive is used to form the case, which is preferably also embossed.

Claims

exact text as granted — not AI-modified
1 . A case for a hard cover book comprising a curable hot melt adhesive.  
     
     
         2 . The case of  claim 1  wherein the case comprises a radiation curable hot melt adhesive.  
     
     
         3 . The case of  claim 2  wherein the radiation curable hot melt adhesive is a UV curable hot melt adhesive.  
     
     
         4 . The case of  claim 1  wherein the case comprises a moisture curable hot melt adhesive.  
     
     
         5 . The case of  claim 1  wherein the adhesive comprises at least one block copolymer comprising a high vinyl styrene-butadiene-styrene block copolymer and a photoinitiator.  
     
     
         6 . The case of  claim 1  wherein the block copolymer is a radial block copolymer.  
     
     
         7 . The case of  claim 1  wherein the block copolymer is a linear block copolymer.  
     
     
         8 . The case of  claim 1  wherein the adhesive comprises a mono epoxidized mono hydrated diene polymer and a photoinitiator.  
     
     
         9 . The case of  claim 1  which is embossed.  
     
     
         10 . The case of  claim 1  comprising cover boards and a porous cover stock.  
     
     
         11 . An embossed product comprising a cured hot melt adhesive.  
     
     
         12 . The product of  claim 11  wherein the cured hot melt adhesive is a radiation cured hot melt adhesive.  
     
     
         13 . The product of  claim 11  wherein the cured hot melt adhesive is a moisture cured hot melt adhesive.  
     
     
         14 . A method of forming a case for a hard cover book comprising bonding cover boards to cover stock material using a curable hot melt adhesive.  
     
     
         15 . The method of  claim 14  wherein the curable adhesive is a radiation curable hot melt adhesive.  
     
     
         16 . The method of  claim 15  wherein the radiation curable hot melt adhesive is a UV curable hot melt adhesive.  
     
     
         17 . The method of  claim 14  wherein the curable adhesive comprises a moisture curable hot melt adhesive.  
     
     
         18 . The method of  claim 15  wherein the adhesive comprises at least one block copolymer comprising a high vinyl styrene-butadiene-styrene block copolymer and a photoinitiator.  
     
     
         19 . The method of  claim 18  wherein the block copolymer is a radial block copolymer.  
     
     
         20 . The method of  claim 18  wherein the block copolymer is a linear block copolymer.  
     
     
         21 . The method of  claim 14  wherein the adhesive comprises a mono epoxidized mono hydrated diene polymer and a photoinitiator.  
     
     
         22 . The method of  claim 14  further comprising embossing the formed case.  
     
     
         23 . A method of  claim 14  wherein the cover stock material is a porous cover stock material.  
     
     
         24 . A casemaking machine comprising a curing apparatus.  
     
     
         25 . The machine of  claim 24  wherein the curing apparatus is the source of actinic or ionizing radiation or a source of moisture.
