Abstract

An anti-fogging and anti-fouling laminate, including: a substrate; and an anti-fogging and anti-fouling layer on the substrate where a surface of the anti-fogging and anti-fouling layer is flat, wherein the anti-fogging and anti-fouling layer is a cured product obtained by curing an active energy ray curable resin composition through an active energy ray, wherein the active energy ray curable resin composition includes a hydrophilic monomer having a radically polymerizable unsaturated group and a photopolymerization initiator, wherein a content of the hydrophilic monomer having a radically polymerizable unsaturated group in the active energy ray curable resin composition is 60% by mass or more, and wherein a surface of the anti-fogging and anti-fouling layer has a pure water contact angle of 90° or more.

First claim

The invention claimed is:

1. An anti-fogging and anti-fouling laminate, comprising:
a substrate; and
an anti-fogging and anti-fouling layer on the substrate where a surface of the anti-fogging and anti-fouling layer is flat,
wherein the anti-fogging and anti-fouling layer is a cured product obtained by curing an active energy ray curable resin composition through an active energy ray,
wherein the active energy ray curable resin composition includes a hydrophilic monomer having a radically polymerizable unsaturated group and a photopolymerization initiator,
wherein the hydrophilic monomer having a radically polymerized unsaturated group is a (meth)acrylate including a polyoxyalkylene chain,
wherein a content of the hydrophilic monomer having a radically polymerizable unsaturated group in the active energy ray curable resin composition is 60% by mass or more, and
wherein a surface of the anti-fogging and anti-fouling layer has a pure water contact angle of 90° or more.

2. The anti-fogging and anti-fouling laminate according to claim 1 , wherein the active energy ray curable resin composition further includes a hydrophobic monomer having a radically polymerizable unsaturated group.

3. The anti-fogging and anti-fouling laminate according to claim 2 , wherein a content of the hydrophobic monomer having a radically polymerizable unsaturated group in the active energy ray curable resin composition is more than 0.018% by mass.

4. The anti-fogging and anti-fouling laminate according to claim 1 , wherein the substrate is a substrate made of a resin or an inorganic substrate.

5. A product, comprising:
the anti-fogging and anti-fouling laminate according to claim 1 on a surface thereof.

6. A method for manufacturing the product according to claim 5 , the method comprising:
heating the anti-fogging and anti-fouling laminate; and
molding the anti-fogging and anti-fouling laminate heated into a desired shape.

7. The method for manufacturing the product according to claim 6 ,
wherein the heating is performed by infrared heating.

8. An anti-fouling method for protecting a product from getting dirty, the method comprising:
laminating an anti-fogging and anti-fouling laminate on a surface of the product, the anti-fogging and anti-fouling laminate being the anti-fogging and anti-fouling laminate according to claim 1 .

9. An active energy ray curable resin composition, comprising:
a hydrophilic monomer having a radically polymerizable unsaturated group;
a hydrophobic monomer having a radically polymerizable unsaturated group; and
a photopolymerization initiator,
wherein the hydrophilic monomer having a radically polymerizable unsaturated group is a (meth)acrylate including a polyoxyalkylene chain,
wherein a content of the hydrophilic monomer having a radically polymerizable unsaturated group in the active energy ray curable resin composition is 60% by mass or more, and
wherein when the active energy ray curable resin composition is cured through an active energy ray to form an anti-fogging and anti-fouling layer, a surface of the anti-fogging and anti-fouling layer has a pure water contact angle of 90° or more.

10. The active energy ray curable resin composition according to claim 9 , wherein the hydrophobic monomer having a radically polymerizable unsaturated group is a (meth)acrylate including at least one of fluorine and silicon.
