Abstract

A method of producing a lenticular printed material includes: an ink jetting step of jetting an aqueous ink, containing a colorant, resin particles, water and a water-soluble high boiling point solvent, onto an ink receiving layer of a lenticular sheet including a resin layer, a lens layer disposed at one surface side of the resin layer, and the ink receiving layer, which is disposed at the other surface side of the resin layer, which contains particles and a resin, and which has a porous structure and a void volume of 50% or greater, according to an ink jetting method; and a drying step of drying the aqueous ink, under conditions in which a surface temperature of the ink receiving layer is set to 30° C. or higher, to form a parallax picture.

First claim

What is claimed is:

1. A method of producing a lenticular printed material, comprising:
an ink jetting step of jetting an aqueous ink, containing a colorant, resin particles, water and a water-soluble high boiling point solvent, onto an ink receiving layer of a lenticular sheet including a resin layer, a lens layer disposed at one surface side of the resin layer, and the ink receiving layer, which is disposed at the other surface side of the resin layer, which contains particles and a resin, and which has a porous structure and a void volume of 50% or greater, according to an ink jetting method; and
a drying step of drying the aqueous ink, under conditions in which a surface temperature of the ink receiving layer is set to 30° C. or higher, to form a parallax picture, wherein a thickness of the ink receiving layer is in a range of from 3 μm to 10 μm.

2. The method of producing a lenticular printed material according to claim 1 , wherein, in the ink jetting step, the aqueous ink is jetted under jetting conditions in which resolution is set to 1200 dpi×1200 dpi or greater, according to the ink jet method, which is a single pass method.

3. The method of producing a lenticular printed material according to claim 1 , wherein, in the ink jetting step, the aqueous ink is jetted under jetting conditions of a minimum liquid droplet size of 3 pl or less.

4. The method of producing a lenticular printed material according to claim 2 , wherein, in the ink jetting step, the aqueous ink is jetted under jetting conditions of a minimum liquid droplet size of 3 pl or less.

5. The method of producing a lenticular printed material according to claim 1 , further comprising:
a position correcting step of correcting a position for jetting the aqueous ink to be jetted onto the ink receiving layer based on position information of the parallax picture on the lens layer.

6. The method of producing a lenticular printed material according to claim 4 , further comprising
a position correcting step of correcting a position for jetting the aqueous ink to be jetted onto the ink receiving layer based on position information of the parallax picture on the lens layer.

7. A lenticular sheet, comprising:
a resin layer;
a lens layer disposed on one surface side of the resin layer; and
an ink receiving layer, which is disposed on the other surface side of the resin layer, contains particles and a resin, and has a porous structure and a void volume of 50% or greater, wherein a thickness of the ink receiving layer is in a range of from 3 μm to 10 μm.

8. The lenticular sheet according to claim 7 , wherein:
the particles are gas phase method silica particles, and
the resin contained in the ink receiving layer is a polyvinyl alcohol-based resin.

9. The lenticular sheet according to claim 7 , wherein the void volume of the ink receiving layer is in a range of from 50% to 75%.

10. The lenticular sheet according to claim 7 , wherein a light transmittance of the ink receiving layer is 80% or greater.

11. The lenticular sheet according to claim 7 , wherein an average primary particle diameter of the particles contained in the ink receiving layer is 2 μm or less.

12. The lenticular sheet according to claim 7 , wherein the void volume of the ink receiving layer is in a range of from 50% to 75%, a light transmittance of the ink receiving layer is 80% or greater, and an average primary particle diameter of the particles contained in the ink receiving layer is 2 μm or less.

13. The lenticular sheet according to claim 7 , further comprising an interlayer which is provided between the resin layer and the lens layer.

14. The lenticular sheet according to claim 13 , wherein the lens layer and the interlayer are coextruded.
