Abstract

Provided are a coating composition including nonionic polymer particles having a number-average primary particle diameter of 5 nm to 200 nm and a hydrolysable silane compound represented by Formula 1, an antireflection film which is a cured substance of the coating composition, a laminate including the antireflection film, a method for manufacturing the laminate, and a solar cell module including the laminate.
In Formula 1, X represents a hydrolysable group or a halogen atom, Y represents a non-hydrolysable group, and n represents an integer of 0 to 2.
(Y n SiX) 4-n   Formula 1

First claim

What is claimed is:

1 . A coating composition comprising:
nonionic polymer particles having a number-average primary particle diameter of 5 nm to 200 nm; and a hydrolysable silane compound represented by Formula 1,
(Y n SiX) 4-n   Formula 1

in Formula 1, X represents a hydrolysable group or a halogen atom, Y represents a non-hydrolysable group, and n represents an integer of 0 to 2.

2 . The coating composition according to claim 1 ,
wherein a content of the hydrolysable silane compound in which n=1 is 90% by mass or more of a total mass of the hydrolysable silane compound.

3 . The coating composition according to claim 1 ,
wherein a proportion of a total mass of the nonionic polymer particles to a total mass of the hydrolysable silane compound is 0.10 or more and 1.00 or less.

4 . The coating composition according to claim 1 , further comprising:
inorganic particles having a number-average primary particle diameter of 3 nm to 100 nm.

5 . The coating composition according to claim 4 ,
wherein the inorganic particles are silica particles.

6 . The coating composition according to claim 4 ,
wherein a proportion of a total mass of the inorganic particles to a total mass of the hydrolysable silane compound is 0.03 or more and 1.00 or less.

7 . The coating composition according to claim 1 ,
wherein a content of an organic solvent is 20% by mass or more of a total mass of the coating composition.

8 . An antireflection film which is a cured substance of the coating composition according to claim 1 .

9 . The antireflection film according to claim 8 ,
wherein an average film thickness is 80 nm to 200 nm.

10 . A laminate comprising:
a base material; and the antireflection film according to claim 8 .

11 . The laminate according to claim 10 ,
wherein the base material is a glass base material.

12 . A solar cell module comprising:
the laminate according to claim 10 .

13 . A method for manufacturing a laminate comprising:
a step of forming a coating film by applying the coating composition according to claim 1 onto a base material; and a step of firing the coating film.
