Photocurable resin composition, ink and coating material

Abstract

Provided is a photocurable resin composition containing an allylic polymer (A) which has excellent adhesion to plastic substrates. The present invention relates to a photocurable resin composition containing an allylic polymer (A), the allylic polymer (A) being produced by polymerization of an allylic compound represented by the following formula (I):

1 . A photocurable resin composition, comprising an allylic polymer (A), the allylic polymer (A) being produced by polymerization of an allylic compound represented by the following formula (I): 
       
         
           
           
               
               
           
         
       
       herein R 1  and R 2  each represent H or CH 3 ; X represents an a-valent group having an unsubstituted saturated or partially unsaturated four- to eight-membered cyclic structure;
 and a represents 2 or 3. 
 
     
     
         2 . The photocurable resin composition according to  claim 1 ,
 wherein the X in formula (I) has any of the following cyclic structures:   
       
         
           
           
               
               
           
         
       
     
     
         3 . The photocurable resin composition according to  claim 1 , further comprising an ethylenically unsaturated compound (B). 
     
     
         4 . The photocurable resin composition according to  claim 1 , further comprising a photopolymerization initiator. 
     
     
         5 . An ink, comprising the photocurable resin composition according to  claim 1 . 
     
     
         6 . A coating material, comprising the photocurable resin composition according to  claim 1 . 
     
     
         7 . The coating material according to  claim 6 , which is an overprint varnish.
