Abstract

To provide a laminate whereby, when a printed layer is formed by an inkjet printing system, the adhesion of the printed layer can be easily maintained and it is possible to obtain a printed matter having excellent durability; a printed matter using said laminate; and a method for producing the printed matter. The laminate comprises a film-shaped substrate 1 containing a first fluorinated polymer and a coating layer 3 present in contact directly with one side or each side of the substrate 1, wherein the coating layer 3 is a coating layer containing a second fluorinated polymer different from the first fluorinated polymer, the visible light transmittance of the substrate is 0% or more than 0%, and when it is more than 0%, the visible light transmittance difference expressed by the following formula (1), of the laminate, is at most 40%. Visible light transmittance difference=(visible light transmittance (%) of the substrate−visible light transmittance of the laminate)/visible light transmittance of the substrate×100 (%) (1).

First claim

What is claimed is:

1. A laminate, comprising:
a film-shaped substrate containing a first fluorinated polymer; and
a coating layer containing a second fluorinated polymer different from the first fluorinated polymer, and directly contacting with one side or each side of the substrate, wherein
visible light transmittance of the substrate is 0%, or more than 0%, and
when the visible light transmittance of the substrate is more than 0%, a visible light transmittance difference calculated by the formula (1), is at most 40%:
Visible light transmittance difference={(visible light transmittance of the substrate—visible light transmittance of the laminate)/visible light transmittance of the substrate}×100(%)  (1).

2. The laminate according to claim 1 , wherein the visible light transmittance difference is from 0 to 10%.

3. The laminate according to claim 1 , wherein the substrate has a thickness of from 25 to 1,000 μm.

4. The laminate according to claim 1 , wherein the first fluorinated polymer is at least one type selected from the group consisting of a vinyl fluoride polymer, a vinylidene fluoride polymer, a vinylidene fluoride-hexafluoropropylene copolymer, a tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride copolymer, a tetrafluoroethylene-propylene copolymer, a tetrafluoroethylene-vinylidene fluoride-propylene copolymer, an ethylene-tetrafluoroethylene copolymer, a hexafluoropropylene-tetrafluoroethylene copolymer, an ethylene-hexafluoropropylene-tetrafluoroethylene copolymer, a perfluoro(alkyl vinyl ether)-tetrafluoroethylene copolymer, a chlorotrifluoroethylene polymer, an ethylene-chlorotrifluoroethylene copolymer and a propylene-chlorotrifluoroethylene copolymer.

5. The laminate according to claim 1 , wherein the second fluorinated polymer has a glass transition temperature of from 20 to 70° C.

6. The laminate according to claim 1 , wherein the second fluorinated polymer has at least one type of polar group selected from the group consisting of a hydroxy group, a carboxy group, an amido group and a glycidyl group.

7. The laminate according to claim 6 , wherein the second fluorinated polymer comprises a monomer unit having the polar group.

8. The laminate according to claim 1 , wherein the second fluorinated polymer comprises a fluoroolefin unit.

9. The laminate according to claim 1 , wherein the substrate further contains an ultraviolet blocking agent.

10. The laminate according to claim 1 , wherein the coating layer further contains an ultraviolet blocking agent.

11. A method, comprising:
printing the laminate according to claim 1 by inkjet printing,
wherein a surface of the laminate having the coating layer is printed.

12. A film-structured building, comprising:
a film material comprising the laminate according to claim 1 .

13. A printed matter, comprising:
the laminate according to claim 1 ; and
a printed layer with a thickness of at least 6 μm directly formed on the coating layer of the laminate.

14. A method for producing a printed matter, comprising:
forming a printed layer by applying and curing a curable composition by an inkjet printing system directly on the coating layer of the laminate according to claim 1 .

15. The method according claim 14 , wherein the curable composition is an ultraviolet-curable curable composition.

16. The laminate according to claim 1 , wherein the visible light transmittance of the substrate is 0%.

17. The laminate according to claim 1 , wherein the visible light transmittance difference is from 0 to 5%.

18. The laminate according to claim 1 , wherein the coating layer forms an outermost layer of the laminate, and the coating layer does not have tackiness at room temperature.

19. The laminate according to claim 1 , wherein the laminate comprises a pair of the coating layers each directly contacting each side of the substrate.

20. The printed matter of claim 13 , wherein the coating layer forms an outermost layer of the laminate, the coating layer does not have tackiness at room temperature, and the printed layer is formed on a part of the coating layer.
