DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a pressed flower is placed on a base material such as glass, ceramics, metal plate, paper, cloth, clothes, etc. The present invention relates to a method for attaching pressed flowers.

[0002]

2. Description of the Related Art Conventionally, when a pressed flower is adhered to the upper surface of a base material with a transparent resin, the pressed flower is stood on the upper surface of the base material or temporarily fixed with an adhesive in consideration of appearance, and the transparent resin is directly applied on the pressed flower. It was a method of flowing and hardening to fix the pressed flower. For this reason, since the transparent resin before curing directly contacts the substrate, if the substrate is made of a material that absorbs the transparent resin, it appears that the substrate has absorbed the transparent resin and the substrate has become wet with water. Was. or,
Because the transparent resin before curing is in direct contact with the pressed flower, the transparent resin easily penetrates from the surface of the pressed flower, especially from the scratched part, and the color of the pressed flower is partially transparent or reacts with the pigment to accelerate the discoloration of the pigment. There was something to do. The air that has stagnated in the gaps between the overlapping petals and leaves, or the air that has stagnated inside the porous substrate, moves when the transparent resin flows or during curing, forming air bubbles. It was visible and needed to remove air bubbles. Although bubbles may be removed at an extremely early stage, it is impossible to remove the bubbles even after the transparent resin starts to harden even a little, and the appearance of the product is significantly reduced. When an ultraviolet curable resin is used as the transparent resin, as described above, the transparent resin sucked into the porous substrate or flower, the transparent resin penetrated into the overlapping portion of the flower or leaf, or the space between the substrate and pressed flower The transparent resin that has entered, that is, the transparent resin that is not directly exposed to light, does not cure for a long time, and the uncured transparent resin seeps out on the back of the base material or the uncured transparent resin that is in contact with the pressed flower Since the resin is chemically unstable, it has reacted with the pigment and accelerated the discoloration of the pigment of the pressed flower.

Pressed flowers are adhered to the adhesive surface, the adhesive surface of the transparent film with the pressed flowers is adhered and fixed so that the upper surface of the substrate is in close contact with the transparent film, and the degassed and defoamed transparent resin is poured onto the transparent film and cured to press flowers. Pressed flower characterized by adhering Adhesion method 4) Pressed flowers are placed on a transparent film large enough to cover the pressed flowers and the base material around the pressed flowers, and the top surface of the base material coated with the adhesive on the top surface is in close contact with the pressed flowers and the transparent film around the pressed flowers. A method of applying a pressed flower, characterized in that a transparent resin decompressed and defoamed under reduced pressure is poured onto the transparent film adhered on the upper surface of the base material, cured and adhered with a pressed flower.

[0005]

According to the present invention, in order to attach the pressed flower to the upper surface of the base material, the pressed flower is placed on the upper surface of the base material, and a transparent film large enough to cover the pressed flower and the upper surface of the base material around the pressed flower is formed around the pressed flower and the pressed flower. Is adhered and fixed so as to be in close contact with the upper surface of the base material, or is adhered and fixed with an adhesive, and the transparent resin degassed under reduced pressure is poured onto the transparent film and cured. Thereby, the base material, the pressed flower, the transparent film, and the transparent resin are integrated, and the pressed flower is fixed to the upper surface of the base material without directly contacting the transparent resin by the transparent film.

When the transparent film is adhered and fixed on the upper surface of the substrate with an adhesive, the adhesive may be applied to both sides of the upper surface of the transparent film or the upper surface of the transparent film or the back surface of the transparent film.
The pressure-sensitive adhesive herein includes a permanent adhesive. or,
Pressed flowers are adhered to the adhesive surface of the transparent film with the adhesive applied to the back surface in a size large enough to cover the pressed flowers and the base material surrounding the pressed flowers, and cover the adhesive surface of the transparent film and the top surface of the substrate closely. After fixing, the transparent resin defoamed under reduced pressure is poured on the transparent film and cured.

Further, the pressed flower is placed on a transparent film large enough to cover the upper surface of the pressed flower and the base material around the pressed flower, and the upper surface of the base material coated with an adhesive on the upper surface is applied to the pressed flower and the transparent film around the pressed flower. Adhering and fixing closely so that the transparent resin that has been degassed and degassed under reduced pressure is poured and cured on the transparent film, and the base material, pressed flowers, transparent film, and transparent resin are integrated, and the transparent film directly contacts the transparent resin. Pressed flowers can be adhered to the upper surface of the substrate without the need. This allows the transparent resin to penetrate the base material and become wet with water, the transparent resin penetrates from the surface and scratches of the pressed flower to accelerate the discoloration and fading of the pressed flower, and the clearance of overlapping petals and leaves In the case of the base material and the gap between the flower and the leaves, or the porous base material, the stagnated air inside the base material does not move to a visible portion in the transparent resin. Further, since the transparent resin does not enter the overlapping portion of the flowers and leaves of the pressed flowers, the curing is not delayed even if an ultraviolet curing resin is used as the transparent resin. In addition, since the transparent resin is degassed under reduced pressure before pouring, invisible small air bubbles and unreacted low-molecular gas in the transparent resin are expanded by the heat of curing and visible with the transparent resin. Since there is no generation or stagnation, no air bubble removal operation is required.
