Material non-adhesive to biological substance, curable composition, and artificial organ and medical instrument using same

Abstract

L represents a linear or branched alkylene group having 3 or 4 carbon atoms.

What is claimed is: 
     
         1 . A curable composition which is used to form a material non-adhesive to a biological substance, containing:
 a sulfobetaine monomer represented by Formula (I) or (II), and a cross-linking agent,   
       
         
           
           
               
               
           
         
         in the formulae, R 1  represents a methyl group, an ethyl group, an n-propyl group, or an isopropyl group, and a plurality of R 1 's may be the same as or different from each other, 
         R 2  represents a hydrogen atom or a methyl group, 
         n represents an integer of 2 to 4, and 
         L represents a linear or branched alkylene group having 3 or 4 carbon atoms, 
         wherein the cross-linking agent is at least one selected from the following formulae (III) to (VI): 
       
       
         
           
           
               
               
           
         
       
     
     
         2 . The curable composition according to  claim 1 , further containing: a polymerization initiator. 
     
     
         3 . The curable composition according to  claim 1 , further containing: a monomer which includes an ethylenically unsaturated group.
