This specification claims the benefit of the filing date of Korean Patent Application No. 10-2012-0136120 filed on November 28, 2012 to the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a printing pattern transferring film, a printing pattern transferring film, a manufacturing apparatus thereof, and a printing pattern transferring method using the same.

In the display substrate, although a photolithography method is mainly used to form a conventional pattern, a pattern forming process is complicated, a manufacturing cost is high, and there is a problem in performance.

Therefore, there has been a need to develop a method that is simpler than the conventional pattern forming method and can improve the performance while reducing the cost.

2. Description of the Related Art Generally, electronic devices such as a liquid crystal display device and a semiconductor device are fabricated by forming patterns of numerous layers on a substrate. In order to form such a pattern, a photolithography process has been mainly used so far. However, in the photolithography process, a predetermined pattern mask must be prepared, chemical etching, and stripping processes must be repeated. Therefore, the fabrication process is complicated, and a large amount of chemical waste harmful to the environment is generated. This leads to an increase in production costs, which reduces the competitiveness of the product. To solve the disadvantages of such a photolithography process, methods for forming a fine pattern through a printing technique have been developed. When a fine pattern is manufactured by a printing technique, the process is simple, consumption of raw materials can be minimized, and manufacturing cost is low.

On the other hand, printing techniques capable of forming fine patterns include gravure printing, offset printing, and screen printing. Of these, offset printing is particularly useful because a relatively fine print pattern can be produced with uniform thickness.

Particularly, in the reverse offset printing process, after ink is applied to a blanket made of polydimethylsiloxane (PDMS) rubber, an unwanted pattern portion is removed by a printing plate, and then the pattern portion remaining in the blanket is transferred to the substrate To form a fine pattern.

A general method of the reverse offset printing process is shown in FIG.

The reverse offset printing method is very popular in terms of cost reduction and production speed in pattern formation. However, in continuous printing, the blanket is swelled by the solvent contained in the ink to obtain a precise pattern There is a problem that it is difficult.

According to an embodiment of the present invention, a method of manufacturing a printing pattern transfer film includes: coating an ink layer on a base film; Removing a portion other than the desired pattern from the ink layer by contacting the printing plate with the ink layer to form a printing pattern layer on the base film; And joining a base film on which the print pattern layer is formed and a release film having a coating layer on one surface thereof.

The step of coating the ink layer and the step of forming the printing pattern layer in the above manufacturing method correspond to the printing method in which the set process is omitted in the conventional reverse offset printing method.

FIG. Also, reference numeral (c) represents a step of transferring a desired pattern portion remaining in the blanket to the substrate in a set-up process in the reverse offset printing method.

The method for manufacturing a printing pattern transfer film according to one embodiment of the present disclosure includes a step of coating ink on a base film instead of the step (a) of applying ink to the blanket of Fig. 3, But does not include a set process corresponding to FIG. 3 (c). Therefore, there is an advantage that the manufacturing process becomes very simple. In addition, since the present specification does not use a blanket, the precision of pattern alignment and the accuracy of alignment are improved by the change of swelling and deswelling degree of the blanket during continuous printing according to the reverse offset printing method There is no problem that can be largely dropped. Therefore, the manufacturing method or the printing method according to one embodiment of the present invention is advantageous in that not only the process is simple, but also the cost is reduced, and the precision of the pattern of the printed product is not deteriorated even in continuous printing.

The manufacturing method according to one embodiment of the present disclosure may further include drying the ink layer to remove the solvent after coating the ink layer. In order for the ink composition to be uniformly coated on the substrate without the occurrence of dewetting pinholes or the like in the coating step, the surface energy of the ink composition may be lower than or similar to the surface energy of the substrate or slightly higher than the substrate M < 2 > / m). The solvent component of the ink composition is largely removed in the drying step, so that the surface energy of the ink layer is increased, and the difference in surface energy between the base film and the ink layer is increased. That is, although the surface energy of the ink before drying is low, it gradually increases as it dries, and the ink is transferred after drying. The surface energy of the ink layer before drying may be 20 mN / m to 30 mN / m, and the surface energy of the ink layer after drying may be 30 mN / m to 50 mN / m. The surface energy of the base film may be 20 mN / m to 40 mN / m, more specifically 20 mN / m to 30 mN / m.

In one embodiment of the present invention, the printing plate is provided with a desired pattern as an engraved portion, and a portion other than a desired pattern is provided as an embossed portion. The printed pattern layer is formed by contacting a raised portion of the printing plate with an ink layer, Can be formed by removing other portions. When the printing plate and the ink layer are in contact with each other, pressure may be applied to remove portions other than the desired pattern from the ink layer. At this time, the pressure may be applied to such a degree that the thickness of the printing plate, the thickness of the base film and the thickness of the ink layer may be reduced by a value of 5 to 100 micrometers, more specifically, 10 to 50 micrometers . At this time, the thickness of the ink layer means the highest value. Specifically, when the point at which the printing plate and the ink layer are contacted is 0, the printing plate is moved in the direction of the substrate film on which the ink layer is coated with 5 to 100 micrometers, more specifically 10 to 50 micrometers Pressure can be applied to move to the point.

In one embodiment of the present invention, the surface energy of the embossed portion is preferably 40 mN / m or more. It is preferable that the surface energy of the printing plate embossing portion is higher than the surface energy of the base film in order to contact the embossed portion of the printing plate with the ink layer applied to the base film to remove an undesired pattern portion of the ink layer from the base film. Since the surface energy of the base film may be 20 mN / m to 40 mN / m, the surface energy of the embossed portion is preferably 40 mN / m or more.

In one embodiment of the present invention, the printing plate may be in the form of a flat plate or a roll.

In the manufacturing method according to one embodiment of the present invention, the step of laminating the release film provided with the coating layer may be such that the entire surface of the print pattern layer and the coating layer are in contact with each other.

In the lapping step, the lapping can be performed by applying heat or pressure. At this time, the heat may be a temperature that does not cause damage to the film, and may be specifically a temperature of room temperature to 100 ° C. In addition, the pressure at this time may be a pressure applied so that the total thickness of the film after laminating is reduced to a thickness of 5 micrometers to 100 micrometers, more specifically 10 micrometers to 50 micrometers, in the total thickness of the film before laminating. Specifically, the thickness of the base film, the thickness of the printing pattern layer formed on the base film, the thickness of the coating layer, and the thickness of the release film are 5 to 100 micrometers, more specifically 10 to 50 micrometers The pressure can be applied to such a degree that the pressure decreases. At this time, the thickness of the print pattern layer means the highest value among the values of the print pattern layer, and the thickness of the coating layer means the highest value among the thickness values of the coating layer. Specifically, when the point at which the surface of the print pattern layer and the surface of the coating layer come into contact with each other at the point of time of lapping is 0, the surface of the print pattern layer is spaced from 5 to 100 micrometers in the direction of the release film provided with the coating layer Meter, more specifically from about 10 micrometers to about 50 micrometers.

In one embodiment of the present disclosure, the coating layer may be a transparent adhesive layer or an adhesive layer, and may specifically include an optical clear adhesive (OCA). The material of the coating layer is not particularly limited, but may include silicon, fluorine, acrylic or urethane.

On the other hand, if the thickness is less than 100 micrometers, It is possible to prevent the problem that the optical characteristics may deteriorate, such as the decrease of the transmittance of the formed substrate or the increase of the haze value.

In one embodiment of the present invention, a first release layer may be further included between the coating layer and the release film. The first release layer is formed so that the release film can be more easily removed from the coating layer during the pattern transfer process. The first release layer may be any material that can be easily separated from the coating layer, but it preferably includes a silicone-based release agent, a fluorine-based release agent, or a fluorine-silicone-based release agent.

For example, when a silicone system is used for the coating layer, a fluorine-based releasing agent may be used to form the first release layer.

In one embodiment of the present invention, the base film serves both to support the print pattern transfer film and to protect the print pattern layer. In addition, any material capable of such a role can be applied.
