持せしめ、かかる凹部のインキを被印刷物に転写
することによつて実施されている。 In gravure printing using intaglio materials, ink is first applied to the entire surface of the plate, the ink adhering to the plate is scraped off with a doctor knife, the ink is retained only in the recesses, and the ink in the recesses is transferred to the substrate. It has been implemented since then.
また、グラビア印刷の変形としてタンポ印刷ま

現性の良い印刷が可能である。 Further, as a modification of gravure printing, curved surface printing called tampo printing or tacho printing is performed. Similar to gravure printing, ink is placed all over the surface of the intaglio plate, scraped off with a doctor knife to retain the ink in the recesses, and then transferred to the surface of a flexible pad such as silicone rubber. This is gravure dry offset printing, which transfers ink by pressing the ink-applied surface of the pad onto a curved printing material, and allows printing to be sharper and more reproducible than screen printing. be.

の印刷を完了できないこともある。 These gravure plates are manufactured by carving plates or cylinders made of metals such as copper and iron to form recesses, or by etching using ferric chloride solution. There is.
Among these methods, the engraving method requires a high level of skill as a handicraft, while the etching method has the drawbacks that, in addition to the pollution prevention treatment of waste liquid, it is difficult to control the depth of the recesses and it takes a long time to make the plate. In order to improve these drawbacks, a net gravure method using photosensitive resin has been proposed (for example, Japanese Patent Laid-Open No. 52-32704).
This is a method in which the unexposed areas are completely eluted with a developer using normal plate making to form recesses, and the process is simple and has the advantage that plates of constant quality can always be obtained. However, when the above-mentioned plate material is used for actual printing, problems arise in that ink does not easily escape from the recesses, the amount of ink transferred is insufficient, and the ink is non-uniform. This is because the bottom surface of the recess is the surface of the support which has been subjected to adhesive treatment, and the affinity of the ink to this surface is excessive. That is, when a photosensitive resin is provided on a metal such as iron or aluminum or a plastic such as a polyester film used as a support, the surface of the support must be adhesively treated to increase adhesive strength. This treatment includes zinc phosphate treatment for iron, graining treatment and anodic oxidation treatment for aluminum, and surface matting treatment and corona discharge treatment for plastics, either alone or in combination. Although this treatment improves the adhesion with the photosensitive layer, it also dramatically improves the ink wetting, and the ink retention on the bottom of the recesses of the plate material is too strong, causing it to leak from the recesses to the printing substrate or pads for tacho printing. The transferability of the ink becomes significantly worse. In addition, when an adhesive layer is formed on the surface of the support, the bottom surface of the concave part of the plate material is an adhesive layer, and since the molecular cohesive force of the adhesive component is relatively small, when it comes into contact with ink, it is exposed to ink vehicle and solvent. This causes swelling and deformation of the recesses, and in addition to excessive ink retention, the transferability of the ink becomes extremely poor, and printing of a predetermined amount may not be able to be completed.

すぐれている。 A positive film is closely attached to the photosensitive resin intaglio material having a laminated structure of the present invention and exposed to actinic rays, and then the unexposed areas are completely removed with a photosensitive resin solvent until the surface of the ink transfer layer is exposed. A recess with a constant depth is formed by this. Similar to the recess forming layer 3', the surface of the ink transfer layer 2 is highly three-dimensionally crosslinked during curing to the extent that it is not attacked by the developing solvent, so it does not swell with ink.
In addition, since the composition is similar to that of the concave forming layer that has improved ink transfer properties as an intaglio material, the amount of ink transfer is sufficient, and the uniformity and stability of the amount of transfer during long-term printing is also good. be. In this respect, it is far superior to photosensitive resin intaglio materials that do not have an ink transfer layer.

である。 The ink transfer layer of the present invention is a resin layer obtained by blending a polymerization component, a polymerization initiator, a stabilizer, a plasticizer, etc. with various base polymers, and then curing the mixture by conventionally known methods such as heating and irradiation with actinic rays. The base polymer and polymerization initiator may be exactly the same as those used for the photosensitive resin layer, or even if they are different, this ink transfer layer after curing can be easily connected to the photosensitive resin layer without an adhesive layer. Any resin may be used as long as it provides a resin with high affinity to the extent that it can be firmly bonded. For example, it is preferable if the polymers in each layer are similar, such as the same solvent-soluble polyamide, because when a photosensitive resin layer is provided on the ink transfer layer, fusion adhesion between the polymers can be expected at the very interface between both layers. . When this ink transfer layer is a resin layer formed by photocuring a photosensitive resin composition, it is particularly suitable from the viewpoint of production efficiency because the same raw materials and composition can be used.

潤などの変形を受けないことから決定される。 The uncured ink transfer layer can be cured by appropriate heat treatment if the resin of the ink transfer layer is a thermosetting type, or by using an ultraviolet exposure device such as an ultra-high pressure mercury lamp or a chemical lamp if it is a photocuring type. This can be done by In the case of an electron beam sensitive type, electron beam irradiation is also possible, and another example is curing by chemical treatment such as insolubilization of partially saponified polyvinyl acetate with glyoxal. The degree of curing is determined by the fact that the photosensitive resin is not eluted by the developing solvent and that it does not undergo deformation such as swelling due to the ink used.

である。 The thickness of the ink transfer layer must be in the range of 2 to 100 μm. That is, if the thickness is less than 2 μm, the ink solvent will penetrate and reach the adhesive treatment layer on the surface of the support, causing a decrease in adhesive strength and deformation of the adhesive layer.
If the thickness is 100 μm or more, problems such as curling and deformation of the plate material due to curing shrinkage and cracks will occur. More preferably, it is in the range of 4 to 70 μm.

る。 It is also possible to mount a suitable cover film on the surface of the photosensitive resin layer for protection. As such a film, polyester film, polypropylene film, polyethylene film, etc. can be used, but polyester film is preferred from the viewpoint of dimensional stability and oxygen barrier properties, and polyethylene terephthalate film is most suitable. Furthermore, if the surface of these films is matted, the matte shape is transferred to the plate surface, making it easy to vacuum-adhere the positive film during plate making. Of course, it is also possible to use the device without attaching these cover films.
