Abstract

The invention provides an aqueous liquid composition containing a water-soluble monomer, a photopolymerization initiator and an aqueous medium and further containing a polymer emulsion, wherein the water-soluble monomer is a monomer that has two or more ethylenically unsaturated bonds and is curable with an active energy ray.

Claims

exact text as granted — not AI-modified
1 . An aqueous liquid composition comprising a water-soluble monomer, a photopolymerization initiator and an aqueous medium and further comprising a polymer emulsion, wherein the water-soluble monomer is a monomer that has two or more ethylenically unsaturated bonds and is curable with an active energy ray. 
     
     
         2 . The liquid composition according to  claim 1 , wherein the water-soluble monomer has a molecular structure satisfying the relationship of the following expression (1):
   3.5≦(Molecular weight of water-soluble monomer)/(28.05×(Number of unsaturated double bonds in molecular structure))≦8.0.   Expression (1)
   
     
     
         3 . The liquid composition according to  claim 1 , wherein the water-soluble monomer has at least one hydroxyl group. 
     
     
         4 . The liquid composition according to  claim 1 , wherein the photopolymerization initiator is a water-soluble acylphosphine oxide compound. 
     
     
         5 . The liquid composition according to  claim 1 , which further comprises a coloring material. 
     
     
         6 . The liquid composition according to  claim 1 , which is used for ink jet. 
     
     
         7 . An ink jet recording method using a liquid composition, wherein the liquid composition comprises a water-soluble monomer, a photopolymerization initiator and an aqueous medium and further comprises a polymer emulsion, wherein the water-soluble monomer is a monomer that has two or more ethylenically unsaturated bonds and is curable with an active energy ray, the method comprising:
 an ejection step of ejecting the liquid composition on a recording medium; and   a curing step of irradiating the recording medium on which the liquid composition has been applied with an active energy ray to cure the water-soluble monomer.   
     
     
         8 . An ink jet recording apparatus comprising a unit for applying the liquid composition according to  claim 7  to a recording medium and a unit for irradiating the liquid composition applied to the recording medium with an active energy ray. 
     
     
         9 . A recorded image formed by the ink jet recording method according to  claim 7 .
