Description

The present invention includes a mat portion having a gloss portions and unevenness feeling to the printing surface is one that relates to the label which is formed on the same printing surface.

  Conventionally, a printed label has been attached to the surface of a packaging container such as a plastic, bottle, or can as a method for appealing the contents of a product to consumers. In particular, a packaging container is required to have a label having a high designability in order to make the printing applied to the label stand out and to make consumers want to purchase the product. Various methods can be used to reproduce high designability by printing, but it is also an effective method to provide a glossy part and matte part on the same printing surface by printing to give high designability to the label. is there. As a method of giving the glossy part and the matte part to the same printing surface, there are a case where the glossy part and the mat part are provided in the same process and a case where the glossy part and the mat part are provided in a different process. The former is a method in which a mat ink containing granular silica or the like is printed on the printing surface and provided in the same process as the glossy portion, and the latter includes granular silica. In this method, mat ink or paint is provided on the printing surface by silk screen printing or applied by a coater, and the glossy portion is processed in a separate process.

  In addition, in the label for mat processing with a feeling of unevenness, the label with the matting feeling of unevenness on the printing surface by pressing or hot pressing with an embossed plate or embossing roll etc. that gives the surface an unevenness shape May be produced.

Furthermore, after forming areas on the surface of the material that are different in ease of wetting from the surface of the electron beam curable paint or light curable paint from the surface of the material by painting, apply the electron beam curable paint or light curable paint. In addition, a method is disclosed in which an easily wetted area is depressed due to a difference in wettability, and an easily wettable area is raised, and then an uneven pattern formed by irradiating an electron beam or light is cured as it is (for example, Patent Document 1).
Japanese Patent Publication No. 51-26937

  However, as a mat processing with a feeling of unevenness, there is a problem that it is difficult to express a matting surface with a feeling of sufficient unevenness by a method of printing or applying a mat ink or paint on the printing surface. On the other hand, it is difficult to give a fine uneven feeling to the printed surface by applying pressure or hot pressing with an embossing plate or embossing roll, etc. There is a problem that it is difficult to match. Furthermore, the method of curing the concavo-convex pattern formed using the electron beam curable paint or the photo-curable paint as it is has a problem that the process of forming the concavo-convex pattern is complicated.

  The present invention has been made in order to solve the above-mentioned problems, and has a glossy part and a matte part with a feeling of unevenness on the same printing surface, has a good production efficiency, and can be processed at low cost. An object of the present invention is to provide a mat-processed label having a certain size.

In order to achieve the above object, the present invention according to claim 1 is a gravure printing on a part or the entire surface of the surface of the printing layer in a label in which a printing layer by gravure printing and an overcoat layer are laminated on a substrate. The overcoat layer is laminated via an underprint layer containing a liquid repellent provided by the electron beam or ultraviolet irradiation by applying an electron beam or an ultraviolet curable coating agent containing a liquid repellent to the overcoat layer. A hardened layer is coated on the surface opposite to the printed layer of the substrate with a mixed liquid containing a humectant, the liquid repellent of the underprint layer is silicon, and the underprint layer is mutually difference in the amount of the silicon in the gravure ink for underprinting layer formation is formed from less than 3% different regions by weight, the lower printing layer, Kotin of the overcoat layer When agent has been applied, repels the coating agent, uneven pattern portion is formed, the other portion is characterized in that it is formed on the glossy portion.

  The label of the present invention can be provided with a pattern printing layer, an underprinting layer, and an overcoat layer using a gravure printing machine to obtain a mat processed label having a glossy portion and a concavo-convex pattern portion having a concavo-convex feeling. It can be done.

  In addition, by performing the printing layer, underprinting layer, and overcoat layer of the pattern in one step using a gravure printing machine, the mat processing has a concavo-convex pattern portion with a concavo-convex feeling that can be processed at low cost and high production efficiency. A label can be obtained.

  In addition, by using an electron beam or UV-curing coating agent containing a liquid repellent in the overcoat layer, the unevenness of the uneven pattern portion formed in the layered portion with the underprint layer becomes finer and more precise. As a result, the surface roughness of the overcoat layer is improved, and the friction resistance of the label and the suitability for automatic packaging of the label are improved.

In addition, the liquid repellent of the underprint layer is silicon, and by forming a plurality of underprint layers having different silicon addition amounts , different coating amounts of silicon are applied when the coating agent for the overcoat layer laminated is applied. There is an effect that the degree of repellency in the printed layer is different, and regions having different unevenness can be formed, and high designability can be obtained.
