Description

  The present invention relates to an embossing method for forming a concavo-convex pattern on the surface of a printed matter, and a printed matter on which a concavo-convex pattern obtained using the method is formed.

  Conventionally, it has been known to obtain a printed material having a three-dimensional effect and a deep design by forming a concavo-convex pattern on the surface of the printed material.

  As a method for forming a concavo-convex pattern on the surface of a printed material, the following method for easily forming a concavo-convex pattern on the surface of a printed material has been proposed.

  For example, a method has been proposed in which a substrate surface is printed with a liquid-repellent ink, then coated with a crosslinkable transparent resin and cured, and then embossed with heat embossing to form an uneven pattern. (For example, refer to Patent Document 1).

  Also, a pattern layer is formed on the base material using a liquid repellent ink, and then an ionizing radiation curable coating composition containing an ionizing radiation polymerizable oligomer, an ionizing radiation polymerizable monomer and a release agent is applied to the pattern. By forming a recess in the coating layer on the top of the pattern layer by the liquid repellent action between the coating layer and the coating layer, when the coating layer is cured with ionizing radiation, an uneven pattern synchronized with the pattern layer is formed. A forming method has been proposed (see, for example, Patent Document 2).

  In addition, the surface tension of the ink is changed to an electron beam or an ultraviolet ray in the formation of a printed matter obtained by printing an aqueous or oil-based ink on a substrate, then applying an electron beam or an ultraviolet curable clear coating, and irradiating and curing with an electron beam or an ultraviolet ray. A method for forming a concavo-convex pattern by making it smaller than an ultraviolet curable clear paint has been proposed (see, for example, Patent Document 3).

  However, the embossed film obtained by the above method is formed of a crosslinkable resin, an active energy ray curable resin, or the like, and is likely to have uniform performance because the width of usable materials is limited. Moreover, when using active energy ray curable resin, the irradiation apparatus which hardens active energy ray curable resin is needed.

  Therefore, the problem of the present invention is that it is technically difficult to form a concavo-convex pattern using a water-based overprint varnish composition on the surface of a printed material, but on the other hand, it can be selected from a wide range of materials such as resins, In addition to physical properties, a novel embossing method for forming a concavo-convex pattern using a water-based overprint varnish composition in which it is easy to adjust viscosity and other characteristic values as a varnish, and a printed product thereof It is.

  When the surface tension of the aqueous overprint varnish composition is lower than (surface tension of the diluted product + 5 mN / m), a good uneven pattern cannot be obtained. It should be noted that even if the surface tension of the aqueous overprint varnish composition is considerably higher than the value of (surface tension of the diluted product + 5 mN / m), there is no particular adverse effect.

  Preferred examples of the aqueous overprint varnish composition include a water-dispersed resin composition, a water-soluble resin varnish, a surface conditioner, and an aqueous solvent.

  The water-dispersed resin in the water-dispersed resin composition is not particularly limited, but is preferably obtained by polymerizing two or more polymerizable monomers including an acrylic monomer. Among these, a copolymer of an acrylic monomer and a styrene monomer is preferable from the viewpoint of good coating film properties.

  The acrylic monomer is not particularly limited, but (meth) acrylic acid esters are preferable. As the (meth) acrylic acid esters, those in which the ester portion is composed of a hydrocarbon group having 1 to 20 carbon atoms are preferable. Specifically, methyl acrylate, ethyl acrylate, n-propyl acrylate, acrylic acid Alkyl acrylates such as isopropyl, n-butyl acrylate, s-butyl acrylate, t-butyl acrylate, hexyl acrylate, lauryl acrylate, methyl methacrylate, ethyl methacrylate, n-propyl methacrylate, methacryl Methacrylic acid alkyl esters such as isopropyl acid, n-butyl methacrylate, s-butyl methacrylate, t-butyl methacrylate, hexyl methacrylate, lauryl methacrylate, and aralkyl (meth) alkylates such as benzyl acrylate and benzyl methacrylate Etc.

  The emulsifier is not particularly limited, and examples thereof include an anionic surfactant and a nonionic surfactant. When improving the water resistance of a coating film, a polymeric anionic surfactant is preferable. Although it does not specifically limit as said anionic surfactant, For example, shellac, the acrylic acid type copolymer which has a carboxyl group, the maleic acid type copolymer which has a carboxyl group, etc. are mentioned. In the emulsion polymerization, the polymer anionic surfactant itself may be used, or an alkaline aqueous solution of the polymer anionic surfactant may be used.

  Further, the water-soluble resin varnish is not particularly limited, but the monomers exemplified for the water-dispersed resin composition (however, a carboxyl group-containing acrylic monomer and / or other carboxyl group-containing unsaturated monomer) And an alkali-soluble copolymer obtained by copolymerizing a base monomer as an essential component and neutralized or partially neutralized with a basic compound and dissolved in water.

Is preferred. From this point, the ratio of the water-dispersed resin composition to the water-soluble resin varnish (in terms of solids) is 40 to 95% by mass of the former and 5 to 60% by mass of the latter based on 100% by mass of both. A range is preferred. If the ratio of the water-soluble resin varnish is less than 5% by mass, coating properties such as leveling properties, gloss, friction resistance, and blocking resistance and printing suitability tend to be inferior. There is a tendency that the uneven pattern forming performance is inferior.

  The surface conditioner contributes to the formation of the concavo-convex pattern of the aqueous overprint varnish composition, particularly based on the function of adjusting the surface tension.

When the content of the surface modifier exceeds 10% by mass, the uneven pattern of the aqueous overprint varnish composition may not be formed.

  The aqueous solvent is not particularly limited, but a mixture of water and a water-miscible organic solvent is preferable. In addition, when the water contained in the water-dispersed resin composition and the water-soluble resin varnish is sufficient, it is not necessary to add water separately. Examples of water miscible organic solvents include monohydric alcohols such as methyl alcohol and ethyl alcohol; polyhydric alcohols such as ethylene glycol, propylene glycol, diethylene glycol and glycerin; ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol mono Alkylene glycol monoalkyl ethers such as butyl ether, ethylene glycol monopentyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monobutyl ether, propylene glycol monohexyl ether; ethylene glycol dimethyl ether, ethylene glycol diethyl ether, ethylene glycol di Butyl ether, ethylene glycol Alkylene glycol dialkyl ethers such as tilethyl ether, ethylene glycol methyl butyl ether, ethylene glycol ethyl butyl ether; ethylene glycol monoacetic acid ester, ethylene glycol monopropionic acid ester, ethylene glycol monopentanoic acid ester, ethylene glycol monohexanoic acid ester, propylene glycol Examples thereof include alkylene glycol monofatty acid esters such as monoacetic acid ester, propylene glycol monopropionic acid ester, propylene glycol monopentanoic acid ester, and propylene glycol monoheptanoic acid ester.

In the embossing method according to the present invention, unevenness of the film (embossed pattern) is caused by the difference in surface tension from the oily overprint varnish composition until the film of the aqueous overprint varnish composition is dried and loses fluidity. It is preferable to appropriately adjust the viscosity and drying property of the aqueous overprint varnish composition according to the materials used and the coating conditions, particularly the difference in film thickness and surface tension.

The oil-based overprint varnish composition is printed on a part or the whole of the printing surface of the base material with an offset printing machine or the like, or coated with a coating machine such as a roll coater, flexo coater, gravure coater or air knife. Then, the aqueous overprint varnish composition is applied onto the surface of the wet oily overprint varnish composition printed or coated using a coating machine such as a roll coater, a flexo coater, a gravure coater or an air knife. Next, for example, the oil-based overprint varnish composition is cured and dried using an infrared drying apparatus, and at the same time, the coating film of the aqueous overprint varnish composition is dried. In this manner, a dry film of the aqueous overprint varnish composition having an uneven pattern is formed.
