Abstract

Provided are a film-forming composition containing a hydrolysate of a siloxane compound represented by Formula (1), silica particles, a ketone-based solvent, and water, and a manufacturing method of a laminate. In Formula (1), R 1 , R 2 , R 3 , and R 4 each independently represent a monovalent organic group having 1 to 6 carbon atoms. n represents an integer of 2 to 20.

First claim

What is claimed is:

1. A film-forming composition comprising:
(a) a hydrolysate of a siloxane compound represented by Formula (1);
(b) silica particles;
(c) a ketone-based solvent;
(d) at least one kind of solvent selected from the group consisting of an alcohol-based solvent, a glycol ether-based solvent, and an ether-based solvent; and
(e) water,

in Formula (1), R 1 , R 2 , R 3 , and R 4 each independently represent a monovalent organic group having 1 to 6 carbon atoms, and n represents an integer of 2 to 20;
wherein a ratio of the total content of the (d) at least one kind of solvent selected from the group consisting of an alcohol-based solvent, a glycol ether-based solvent, and an ether-based solvent to the content of the (c) ketone-based solvent in the film-forming composition is 0.1 to 16.5 based on mass.

2. The film-forming composition according to claim 1 , further comprising:
at least one kind of resin selected from the group consisting of a urethane-based resin and a (meth)acrylic resin.

3. The film-forming composition according to claim 2 ,
wherein the (meth)acrylic resin is a polyacrylic acid.

4. A manufacturing method of a laminate, comprising:
forming a film by applying the film-forming composition according to claim 1 onto a substrate.

5. The manufacturing method of a laminate according to claim 4 ,
wherein the film-forming composition further comprises at least one kind of resin selected from the group consisting of a urethane-based resin and a (meth)acrylic resin.

6. The manufacturing method of a laminate according to claim 5 ,
wherein the (meth)acrylic resin is a polyacrylic acid.

7. The manufacturing method of a laminate according to claim 4 ,
wherein the substrate is a polycarbonate substrate or a polymethyl methacrylate substrate.
