Hardcoat laminate

Abstract

A hardcoat laminate including: a support formed from a thermoplastic resin composition; and a hardcoat layer formed from a hardcoat layer forming coating composition, wherein the thermoplastic resin composition contains a polymer having a lactone ring unit or a glutaric anhydride unit, and the hardcoat layer forming coating composition contains at least a component (a), a component (b) and a component (c) and contains substantially no organic solvent: (a) a curable compound having three or more polymerizable groups within one molecule, (b) a polymerization initiator, and (c) a diluent having from one to three polymerizable groups within one molecule.

1 . A hardcoat laminate comprising:
 a support formed from a thermoplastic resin composition; and a hardcoat layer formed from a hardcoat layer forming coating composition,   wherein the thermoplastic resin composition contains a polymer having a lactone ring unit or a glutaric anhydride unit, and   the hardcoat layer forming coating composition contains at least a component (a), a component (b) and a component (c) and contains substantially no organic solvent:   (a) a curable compound having three or more polymerizable groups within one molecule,   (b) a polymerization initiator, and   (c) a diluent having from one to three polymerizable groups within one molecule.   
   
   
       2 . The hardcoat laminate of  claim 1 , wherein the three or more polymerizable groups in the component (a) are acryloyl groups or methacryloyl groups and the one to three polymerizable groups in the component (c) are acryloyl groups or methacryloyl groups. 
   
   
       3 . The hardcoat laminate of  claim 1 , wherein the diluent of the component (c) has two (meth)acryloyl groups within one molecule. 
   
   
       4 . The hardcoat laminate of  claim 1 , wherein the polymer having a lactone ring unit has a unit represented by the following formula (1): 
     
       
         
         
             
             
         
       
     
     wherein R 11 , R 12  and R 13  each independently represents a hydrogen atom or an organic residue having 1 to 20 carbon atoms, and the organic residue may contain an oxygen atom. 
   
   
       5 . The hardcoat laminate of  claim 1 , wherein the polymer having a glutaric anhydride unit has a unit represented by the following formula (3): 
     
       
         
         
             
             
         
       
     
     wherein R 31  and R 32  each independently represents a hydrogen atom or an organic residue having 1 to 20 carbon atoms, and the organic residue may contain an oxygen atom. 
   
   
       6 . The hardcoat laminate of  claim 1 , wherein the thermoplastic resin composition further contains a copolymer having a vinyl cyanide-based monomer unit and an aromatic vinyl-based monomer unit.
