Ink composition, ink jet recording method, method of producing planographic printing plate, and planographic printing plate
The present invention provides an ink composition including a polymerization initiator and a monofunctional (meth)acrylate having a —CONH— bond in the molecule thereof. The present invention also provides an ink jet recording method and a planographic printing plate producing method using the ink composition, and a planographic printing plate prepared by the planographic printing plate producing method.
1. An ink jet recording method, comprising:
ejecting an ink composition onto a recording medium; and
irradiating the ink composition with active radiation rays to cure the ink composition,
wherein the ink composition comprises a polymerization initiator and a monofunctional (meth)acrylate having a —CONH— bond in a molecule thereof.
2. The ink jet recording method of claim 1 , wherein the ink composition further comprises a colorant.
3. A method of producing a planographic printing plate, comprising:
ejecting an ink composition onto a hydrophilic support; and
irradiating the ink composition with active radiation rays to cure the ink composition and thereby form a hydrophobic image,
wherein the ink composition comprises a polymerization initiator and a monofunctional (meth)acrylate having a —CONH— bond in a molecule thereof.
4. The method of claim 3 , wherein the ink composition further comprises a colorant.
5. The method of claim 3 , wherein the ink composition is ejected by an ink jet recording process.
6. The method of claim 4 , wherein the ink composition is ejected by an ink jet recording process.
7. A planographic printing plate prepared by the method of claim 3 .
