Vehicle mirror and manufacturing method therefor
The present invention provides a vehicle mirror and a manufacturing method therefor which allow the rear face side of a mirror element to be dark-colored without using a color plate or color coating. A mirror element is configured by forming a semitransparent reflective film made of a dielectric multilayer film on the front face of a flat transparent substrate. A dark-colored self-adhesive film is attached to the rear face of the mirror element. The dark-colored self-adhesive film is configured by forming an adhesive layer on the rear face of a dark-colored film layer by means of application. Grid-like air release channels are formed at fine pitches with minimal depth on an entire surface of the adhesive layer. After the dark-colored self-adhesive film is attached to the rear face of the mirror element, the grid-like air release channels visible from a front side of the mirror element are eliminated by heating and/or pressurizing.
1. A vehicle mirror comprising:
a mirror element in which a semitransparent reflective film is formed on a front face or a rear face of a transparent substrate; and
a dark-colored self-adhesive film which is attached to a rear face of the mirror element and which has an attaching side which is dark-colored, wherein
the dark-colored self-adhesive film has air release channels on a surface of an adhesive layer before the dark-colored self-adhesive film is attached to the mirror element, and when the dark-colored self-adhesive film is heated or pressurized after being attached to the mirror element, the air release channels are eliminated as viewed from a front side of the mirror element.
2. The vehicle mirror according to claim 1 , wherein the air release channels are formed in a grid.
3. The vehicle mirror according to claim 2 , wherein the semitransparent reflective film is a dielectric multilayer film.
4. The vehicle mirror according to claim 3 , wherein the rear face of the mirror element has a region not covered with the dark-colored self-adhesive film and a light-emitting information display monitor is installed behind the mirror element with a display surface facing the region not covered with the dark-colored self-adhesive film.
5. The vehicle mirror according to claim 2 , wherein the rear face of the mirror element has a region not covered with the dark-colored self-adhesive film and a light-emitting information display monitor is installed behind the mirror element with a display surface facing the region not covered with the dark-colored self-adhesive film.
6. The vehicle mirror according to claim 1 , wherein the semitransparent reflective film is a dielectric multilayer film.
7. The vehicle mirror according to claim 6 , wherein the rear face of the mirror element has a region not covered with the dark-colored self-adhesive film and a light-emitting information display monitor is installed behind the mirror element with a display surface facing the region not covered with the dark-colored self-adhesive film.
8. The vehicle mirror according to claim 1 , wherein the rear face of the mirror element has a region not covered with the dark-colored self-adhesive film and a light-emitting information display monitor is installed behind the mirror element with a display surface facing the region not covered with the dark-colored self-adhesive film.
9. A manufacturing method for a vehicle mirror, comprising:
preparing a mirror element in which a semitransparent reflective film is formed on a front face or a rear face of a transparent substrate;
preparing a dark-colored self-adhesive film which has an attaching side which is dark-colored and which has air release channels formed on a surface of an adhesive layer before the dark-colored self-adhesive film is attached to a target surface;
attaching the dark-colored self-adhesive film to a rear face of the mirror element; and
heating or pressurizing the mirror element with the dark-colored self-adhesive film attached thereto, thereby eliminating the air release channels as viewed from a front side of the mirror element.
10. The manufacturing method according to claim 9 , wherein the air release channels are formed in a grid.
11. The manufacturing method according to claim 10 , wherein the semitransparent reflective film is a dielectric multilayer film.
12. The manufacturing method according to claim 11 , wherein when the dark-colored self-adhesive film is attached to the rear face of the mirror element, a region of the rear face of the mirror element is not covered by the dark-colored self-adhesive film, and
the manufacturing method further comprises installing a light-emitting information display monitor behind the mirror element with a display surface facing the region of the rear face of the mirror element not covered with the dark-colored self-adhesive film.
13. The manufacturing method according to claim 10 , wherein when the dark-colored self-adhesive film is attached to the rear face of the mirror element, a region of the rear face of the mirror element is not covered by the dark-colored self-adhesive film, and
the manufacturing method further comprises installing a light-emitting information display monitor behind the mirror element with a display surface facing the region of the rear face of the mirror element not covered with the dark-colored self-adhesive film.
14. The manufacturing method according to claim 9 , wherein the semitransparent reflective film is a dielectric multilayer film.
15. The manufacturing method according to claim 14 , wherein when the dark-colored self-adhesive film is attached to the rear face of the mirror element, a region of the rear face of the mirror element is not covered by the dark-colored self-adhesive film, and
the manufacturing method further comprises installing a light-emitting information display monitor behind the mirror element with a display surface facing the region of the rear face of the mirror element not covered with the dark-colored self-adhesive film.
16. The manufacturing method according to claim 9 , wherein when the dark-colored self-adhesive film is attached to the rear face of the mirror element, a region of the rear face of the mirror element is not covered by the dark-colored self-adhesive film, and
the manufacturing method further comprises installing a light-emitting information display monitor behind the mirror element with a display surface facing the region of the rear face of the mirror element not covered with the dark-colored self-adhesive film.
