BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 6, a substrate with braille is provided with a transparent resin layer 12 on a substrate 11, and a projection 1 on the transparent resin layer 12 showing a braille representing an automatic door.
3 are formed. The substrate 13 is formed of a polyester film to a thickness of 50 μm,
On its back surface, a vapor deposition layer 14 is formed by vapor deposition using aluminum. On the surface of the substrate 11, characters 15 of an automatic door and characters 16 of AUTODOOR are printed.

The vapor deposition layer 14 prevents the lower part of the substrate with braille from being seen through, the transparent resin layer 12 looks white, the letters 15 of the automatic door and the letters 1 of AUTODOOR.
6 makes it look sharp. Automatic door and AUTO
DOOR characters 15 and 16 are printed by a screen printing method using silk screen.

The transparent resin layer 12 is formed by applying a urethane resin on the substrate 11 and curing it at normal temperature. This urethane resin is obtained by reacting a polyol such as a diol or a triol with a polyisocyanate such as isophorone diisocyanate. More specifically, it is obtained by reacting a diol, a triol and an excess of isophorone diisocyanate to produce a prepolymer, and further reacting a mixture of a diol and a triol. This transparent resin layer 12 is formed to a thickness of about 2 mm.

The transparent resin layer 12 protects the automatic door printed on the substrate 11 and the letters 15 and 16 of AUTODOOR, expresses a lens function, and makes the letters 15 and 16 underneath appear to protrude. Enhance the feeling. In addition, the deterioration of the characters 15 and 16 due to ultraviolet rays is prevented, and the durability is enhanced.

An adhesive is applied to the back surface of the vapor deposition layer 14 to form an adhesive layer 17.
A release paper 18 is adhered to. Then, the release paper 18 is peeled off, and the substrate 11 is attached to a predetermined location, so that the substrate 11 can be positioned and fixed to the predetermined location via the adhesive layer 17.

The projections 13 representing Braille are formed by irradiating ultraviolet rays after printing an ultraviolet curing ink of an acrylic resin by a screen printing method using a silk screen. The projection 13 has a mountain-shaped cross section, and its height is about 0.5 mm. Here, the resin that forms the protrusion in the present invention refers to a synthetic resin that can be configured as Braille.

The protrusion 21 of the resin liquid flows from the center to the periphery due to the viscosity of the resin liquid, and has a mountain-shaped cross section due to the surface tension of the resin liquid. It is about half, that is, about 0.25 mm. Since the acrylic resin ultraviolet curing ink has a high viscosity, the height of the projection 13 is increased, and the shape of the projection 13 is easily formed into a mountain-shaped cross section. Subsequently, when ultraviolet light (UV) is irradiated from above the resin liquid protrusion 21 by an ultraviolet light irradiation device,
The protrusion 21 of the resin liquid is hardened and the base protrusion 22 shown in FIG.
Is formed.

Next, as shown in FIG.
The silk screen 19 is arranged again on the transparent resin layer 12 on which the is formed, and the ultraviolet curing ink of the acrylic resin is screen-printed, so that the resin liquid is formed on the base projections 22 corresponding to the projection forming holes 20. Coated and formed. At this time, the resin liquid flows from the center on the base projection 22 to the periphery. In this state, the ultraviolet light was
By irradiating for up to 6 seconds, as shown in FIG.
3 is formed. The protrusion 13 has a height of about 0.5 mm.
