摘要
The present invention relates to a method for producing a multi-purpose ink-jet print film and a multi-purpose ink-jet print film for the same. More specifically, the present invention relates to a multi- Producing an integral film sheet; And (b) directly coating a sol coating liquid containing pigments or dyes on one side of the polyethylene film adhered to the prepared integral type film; The present invention also provides a method for producing a printing film for a multi-purpose ink jet and a printing film for a multi-purpose ink jet produced by the method. When the method according to the present invention is used, there is an advantage that the base film can be protected without being damaged and thus the uniformity of the thickness can be secured, and the process can be simplified, The cost can be reduced. In addition, since the polyethylene film has a buffering action and is hardly affected by the sol coating solution, the shape stability of the base film can be enhanced. Since moisture from the outside is not transferred to the base film, It is not necessary to manufacture various product groups for each material and it is advantageous that only the thickness of each film can be changed for various purposes by changing the thickness of each film according to the demand of the consumer. In addition, it is advantageous in that the production cost can be further reduced by reducing the thickness of the expensive base film and by using a relatively low-cost polyethylene film on both sides thereof.
