Abstract

Provided is a laminate including a substrate, a primer layer disposed on the substrate, and a functional layer disposed on the primer layer, where the functional layer has a function of at least one of an anti-fogging property and an anti-fouling property, wherein a surface of an edge portion of the laminate at the side of the functional layer has a projected portion having an apex formed along an edge side of the edge portion, and on a cross-section orthogonal to a direction of the edge side and a planar direction of the surface, a height of the projected portion is 10 μm or less, a width of the projected portion is 15 mm or less, and a length between the edge side and the apex is 5.0 mm or less.

First claim

What is claimed is:

1. A laminate comprising:
a substrate;
a primer layer disposed on the substrate; and
a functional layer disposed on the primer layer, where the functional layer has a function of at least one of an anti-fogging property or an anti-fouling property,
wherein a surface of an edge portion of the laminate at the side of the functional layer has a projected portion having an apex formed along an edge side of the edge portion,
on a cross-section orthogonal to a direction of the edge side and a planar direction of the surface, a height of the projected portion is 10 μm or less, a width of the projected portion is 15 mm or less, and a length between the edge side and the apex is 5.0 mm or less,
wherein the primer layer is a cured product of an active energy-ray curable resin composition, and
the active energy ray curable resin composition includes a surfactant.

2. The laminate according to claim 1 ,
wherein a height of the projected portion is from 1 μm to 10 μm.

3. The laminate according to claim 1 ,
wherein a surface of the functional layer has a pure water contact angle of 80° or more and a hexadecane contact angle of 35° or more.

4. The laminate according to claim 1 ,
wherein the primer layer has an average thickness of from 0.5 μm to 5 μm.

5. The laminate according to claim 1 ,
wherein the functional layer has an average thickness of 10 μm or more.

6. The laminate according to claim 1 ,
wherein the functional layer has a coefficient of dynamic friction of 0.40 or less.

7. The laminate according to claim 1 ,
wherein the surfactant is at least one of a silicone-based surfactant and a fluorine-based surfactant.

8. The laminate according to claim 1 ,
wherein an amount of the surfactant in the active energy ray curable resin composition is from 0.0001% by mass to 5.0% by mass relative to a non-volatile component of the active energy ray curable resin composition.

9. A product comprising:
the laminate according to claim 1 on a surface of the product.

10. The product according to claim 9 ,
wherein the product is a mirror.

11. The product according to claim 10 ,
wherein the product is at least one of a mirror for bathrooms, and a mirror for washstands.

12. The product according to claim 10 ,
wherein an image of a wire mesh appeared in the mirror is not distorted when the wire mesh having an opening size of 1 cm is placed at a position that is 1 m away from a surface of the mirror in the normal direction relative to the surface of the mirror and the image of the wire mesh appeared in the mirror is visually evaluated.

13. An active energy ray curable resin composition comprising:
a surfactant,
wherein the active energy ray curable resin composition is used for forming the primer layer of the laminate according to claim 1 .

14. The active energy ray curable resin composition according to claim 13 ,
wherein the surfactant is at least one of a silicone-based surfactant and a fluorine-based surfactant.

15. The active energy ray curable resin composition according to claim 13 ,
wherein an amount of the surfactant in the active energy ray curable resin composition is from 0.0001% by mass to 5.0% by mass relative to a non-volatile component of the active energy ray curable resin composition.

16. A method for manufacturing the laminate according to claim 1 , the method comprising:
applying an active energy ray curable resin composition including a surfactant onto the substrate and curing the active energy ray curable resin composition to form the primer layer.

17. The method according to claim 16 ,
wherein the surfactant is at least one of a silicone-based surfactant and a fluorine-based surfactant.

18. The method according to claim 16 ,
wherein an amount of the surfactant in the active energy ray curable resin composition is from 0.0001% by mass to 5.0% by mass relative to a non-volatile component of the active energy ray curable resin composition.
