JPH0688446B2 - Printing method on the adhesive surface of the slightly adhesive film and urethane foam adsorption film - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention maintains the adhesive effect on the adhesive surface of a slightly adhesive film coated with a slightly adhesive agent or a urethane foam adsorption film obtained by coating a urethane foaming agent with a heat-resistant film. At the same time, it relates to a printing method capable of performing desired printing.

(Prior art) Conventionally, a non-sticky film coated with a pressure-sensitive peelable pressure-sensitive adhesive or a urethane foam-adsorbed film in which a urethane foaming agent is applied to a heat-resistant film and a urethane foam layer has adsorptivity Print desired patterns and letters on the adhesive surface,
Those that are adhered to a wall surface, glass, a board, etc. are known and widely used as stickers, advertisements, and advertising media.

However, it has been extremely difficult to print the adhesive surface of such a slightly adhesive film or urethane foam adsorption film. For example, in the case of a slight adhesive film, a film to which no adhesive is applied is subjected to printing processing, and then a slight adhesive is applied to the printed surface to exert an adhesive action. However, since the slight pressure-sensitive adhesive layer is formed on the printed surface, the printed surface is not beautiful. Also, for urethane foam adsorption film,
Since the urethane foam layer is not transparent, the printing method used for the slightly adhesive film can be adopted at all, and it is practically impossible to obtain a urethane foam adsorption film having a printed adhesive surface.

(Problems to be Solved by the Invention) Therefore, according to the present invention, it is possible to easily perform desired printing on the adhesive surface of the slightly adhesive film or the urethane foam adsorption film, and to maintain the adhesive action. It is something to do.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by the present invention are
After adhering the ultra-thin film to the entire adhesive surface of the slightly adhesive film or urethane foam adsorption film, print the desired characters, figures, etc. on the surface of the ultra-thin film and cut off a part of the ultra-thin film after printing. It is characterized in that the adhesive surface is exposed to the outside.

(Working) A special printing technology is used because the ultra-thin film is attached to the entire adhesive surface of the slightly adhesive film or urethane foam adsorption film and the surface of the attached ultra-thin film is printed. Without using the general printing means. After printing, the portion of the ultra-thin film to be bonded is cut off to expose the bonding surface and exert the bonding action.

(Effect of the Invention) According to the present invention, desired printing can be easily performed by a general means on the adhesive surface of the slightly adhesive film or the urethane foam adsorption film, which has been difficult to print conventionally. The adhesive action is maintained without any trouble, and a film having a printed adhesive surface can be easily obtained.

(Embodiment) A preferred embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an example of using the film according to the present invention,
(1) is the desired character, pattern, or figure (3) on the adhesive surface (2)
Etc. is a printed film, and can be attached to the adhered object (4), for example, the back surface of transparent glass, and can be visually recognized from the surface of the adhered object (4).

The film (1) is a micro-adhesive film coated with a peelable pressure-sensitive micro-adhesive, or a urethane foam adsorption film whose urethane layer has a suction cup adsorption effect by applying a urethane foaming agent to a heat-resistant film and foaming. Is.
2-5, (1) shows such a film,
(5) shows an adhesive layer formed on one surface of the film (1) and made of a slight adhesive or urethane foam.

When printing, first, as shown in FIG. 3, the adhesive layer (5)
An ultra-thin film, for example, a polyester resin film (6) having a thickness of 50 μm is adhered to the entire surface of, and the surface of the adhered ultra-thin film (6) is subjected to a general printing means such as offset printing or silk printing. A desired character, pattern, figure (3), etc. are printed. Next, the unprinted portion of the ultrathin film (6) is cut off to expose the adhesive layer (5) to the outside (FIG. 4). Then, as shown in FIG. 5, the exposed adhesive layer (5) is adhered to the adherend (4). As a result, the printed surface can be visually recognized through the adherend object (4), and can be attached from the inside to the window of an automobile or a building and viewed from the outside.
