版印刷原版に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is attached to a thermal printer or the like, and by directly making plates with a thermal head, it is possible to obtain clear printed matter without using dampening water. The present invention relates to a heat-sensitive lithographic printing original plate for producing a lithographic printing plate.
一般に平版印刷原版としては、

などがあげられる。
In general, lithographic printing original plates include (1) a PS plate consisting of an aluminum plate with a grained surface and a photosensitive layer thereon; (2) a photoconductive plate made of zinc oxide or the like on a support such as paper; Master plates that can be electrophotographically engraved with a layered structure (3) Direct printing masters that have a structure in which the surface of the support has been subjected to hydrophilic treatment.

性部分は湿し水を弾いて、油性インクを受容する
ことにより、画像部と非画像部がえられ、それに
より転写印刷が可能となる。 The surface of each of these original plates has been treated to make it hydrophilic, and plate making is performed by attaching a lipophilic substance to the portion of the surface corresponding to the image. During printing, the non-image area is hydrophilic, so it repels oil-based ink with dampening water, while the lipophilic area of the image area repels dampening water and receives oil-based ink, thereby separating the image area and non-image area. transfer printing becomes possible.

However, since the difference between so-called hydrophilicity and lipophilicity between image areas and non-image areas is small, the influence of dampening water is large; for example, if excessive dampening water is applied, the lipophilic areas of image areas become wet. Water may remain and repel oil-based ink. On the other hand, if there is less dampening water, there will be less water in the non-image area, which is a hydrophilic area, resulting in problems such as poor repellency of oil-based ink and the occurrence of scumming.

To provide an original plate that can be directly made into a plate without using it and without requiring a developing process.

The present invention is an original plate that provides a lithographic printing plate that can be made using a thermal head and that can be printed without dampening water, which comprises a stretched thermoplastic synthetic resin film with a thickness of 0.5 to 5 μm on a support. The present invention relates to a heat-sensitive lithographic printing original plate characterized in that the synthetic resin film is laminated with an oil-repellent layer provided on the surface of the synthetic resin film.
つぎに本発明を図面に基づいて説明する。 Next, the present invention will be explained based on the drawings.
第１図は本発明の平版印刷原版の一実施例を示
す概略部分断面図である。 FIG. 1 is a schematic partial sectional view showing an embodiment of the lithographic printing original plate of the present invention.
１は支持体であり、支持体１上には接着剤層２

には撥油層４が設けられている。 1 is a support, and on the support 1 is an adhesive layer 2.
Thermoplastic synthetic resin film 3 stretched through

前記支持体１としては、紙またはプラスチツク

150ｇ／m2、厚さ80〜140μの紙である。 Paper or plastic film can be used as the support 1, but preferably has a basis weight of 60 to 60.
The paper weighs 150 g/m 2 and has a thickness of 80 to 140 μ.

リデン樹脂フイルムが好ましい。 A stretched synthetic resin film 3 having a thickness of 0.5 to 5 μm is laminated onto this support 1 using a suitable adhesive. Examples of the synthetic resin film include polyester film, polycarbonate film, vinyl chloride resin film, vinylidene chloride resin film, and vinylidene fluoride resin film, with polyester film and vinylidene fluoride resin film being particularly preferred.

サーマルヘツドの熱エネルギーによる溶融製版が
不充分となり、鮮明な画像がえられない。 The thickness of the film is 0.5-5μ, preferably 1-5μ.
It needs to be 3μ. During printing, the surface of the synthetic resin film comes into pressure contact with the inking roller and bracket and is repeatedly subjected to mechanical forces, so if the film thickness is less than 0.5 μm, it cannot withstand this force. When the film thickness exceeds 5μ,
The thermal energy of the thermal head causes insufficient melting and printing, making it impossible to obtain clear images.

Examples include wax and surfactants, but silicone resins are particularly preferred. Further, these oil repellents may be mixed and used as appropriate.

融製版性が悪くなる。 The oil repellent can be dissolved in a suitable solvent such as methyl ethyl ketone, toluene, ethyl acetate, etc.
It is applied to the surface of the film by dispersion or as a coating material dispersed or dissolved in water. The application amount varies depending on the type of oil repellent, but the dry application amount is 0.1~
3 g/m 2 , especially 0.3 to 0.7 g/m 2 . If the coating amount is less than 0.1 g/m 2 , the oil repellent effect will be poor, and if the coating amount is poorly controlled during coating, uncoated areas will easily occur, which is not preferable.
On the other hand, if the coating amount exceeds 3 g/m 2 , the coating film becomes thick and the melting plate-making properties of the synthetic resin film using a thermal head deteriorate.
なおシリコーン樹脂はすぐれた撥油効果を有す
ることに加えて、製版時においてサーマルヘツド

り、とくに好ましい。 In addition to having an excellent oil repellent effect, silicone resin is particularly preferred since it has the effect of preventing the thermal head and the synthetic resin film from fusing together during plate making.
前記撥油層の中には着色剤を適宜分散させても
よい。 A coloring agent may be appropriately dispersed in the oil-repellent layer.
前述した構成の感熱性平版印刷原版をサーマル

画像部７を構成する。 Figure 2 shows the state during plate making. In FIG. 2, reference numeral 5 denotes a thermal head, and the synthetic resin film 3 and oil repellent layer 4 in the portions of the thermal head 5 corresponding to the energized heating elements are melted to form a recess, and this recess is the image area 6. becomes. The oil-repellent layer 4 remains in the unmelted portion and forms a non-image portion 7.

に付着するためである。 When the thus obtained lithographic plate is used for printing with a lithographic printing machine, ink does not adhere to the non-image area 7 even without dampening water, and a printed matter with very little scumming can be obtained. The reason for this is that ink does not adhere to the non-image area 7 due to the presence of the oil-repellent layer 4, whereas in the image area 6, the oil-repellent layer 4 is melted, so there is no oil-repellent effect and the ink does not stick to the non-image area 7. This is for good adhesion.
