Abstract

A method of manufacturing printed matter includes applying a curable composition to a water-absorptive substrate, wherein the curable composition has a moisture content ratio of 0.4 percent by mass or less.

First claim

What is claimed is:

1. A method of manufacturing printed matter, comprising:
applying a curable composition to a water-absorptive substrate,
wherein the curable composition has a moisture content ratio of 0.4 percent by mass or less; and
wherein a total amount of hydrophilic monomer in the curable composition is from 10 percent by mass to 30 percent by mass.

2. The method according to claim 1 , further comprising curing the curable composition with a curing device.

3. The method according to claim 1 , wherein the curable composition has a moisture content ratio of 0.2 percent by mass or less.

4. The method according to claim 1 , wherein the total amount of the hydrophilic monomer in the curable composition is from 10 to 20 percent by mass.

5. The method according to claim 1 , wherein the hydrophilic monomer contains at least one of a hydroxyl group, an amino group, and a carboxyl group.

6. The method according to claim 1 , wherein the hydrophilic monomer comprises at least one of an acryloylmorpholine, hydroxyethyl acrylate, and 2-acryloyloxyethyl hexahydro phthalic acid.

7. The method according to claim 1 , wherein the water-absorptive substrate comprises a water-absorptive inorganic substrate.

8. The method according to claim 7 , wherein the water-absorptive inorganic substrate comprises a gypsum board.

9. The method according to claim 1 , wherein the curable composition is applied by an inkjet printing method.

10. The method according to claim 1 , further comprising:
curing the curable composition to obtain cured matter,
wherein the water-absorptive substrate is a building material substrate, and
wherein the cured matter has a moisture content of 0.06 g/m 2 or less.

11. Printed matter produced by the method of manufacturing printed matter of claim 1 .

12. The printed matter according to claim 11 , comprising:
the water-absorptive substrate; and
cured matter of the curable composition on a surface of the water-absorptive substrate in an amount of 15 g/m 2 or more,
wherein the water-absorptive substrate has a warp of 1 mm or less.

13. A method of manufacturing printed matter, comprising:
applying a curable composition to a water-absorptive substrate that comprises an inorganic substrate,
wherein the curable composition has a moisture content ratio of 0.4 percent by mass or less;
a total amount of hydrophilic monomer in the curable composition is from 10%-20% by mass; and
the hydrophilic monomer comprises at least one of an acryloylmorpholine, hydroxyethyl acrylate, and 2-acryloyloxyethyl hexahydro phthalic acid.

14. A method of manufacturing printed matter, comprising:
applying a curable composition to a water-absorptive substrate,
wherein the curable composition has a moisture content ratio of 0.4 percent by mass or less;
wherein the curable composition comprises at least one hydrophilic monomer selected from the group consisting of an acryloylmorpholine, hydroxyethyl acrylate, and 2-acryloyloxyethyl hexahydro phthalic acid, in a total amount of greater than 0 percent by mass and up to 30 percent by mass in the curable composition.

15. The method according to claim 14 , wherein the at least one hydrophilic monomer comprises acryloylmorpholine.

16. The method according to claim 14 , wherein the at least one hydrophilic monomer comprises hydroxyethyl acrylate.

17. The method according to claim 14 , wherein the at least one hydrophilic monomer comprises 2-acryloyloxyethyl hexahydro phthalic acid.
