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.

などがあげられる。[Prior art] 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 zinc oxide plate on a support such as paper; (3) A master plate that can be electrophotographically engraved with a photoconductive layer consisting of a photoconductive layer, and a direct drawing master with a hydrophilic treatment applied to the surface of the support.

し水により油性インクを弾き、一方画像部の親油
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.

The present invention relates to a heat-sensitive lithographic printing original plate, characterized in that a stretched thermoplastic synthetic resin film having a thickness of 0.5 to 5 μm is laminated to the surface of the film, and an oil-repellent layer is 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

樹脂フイルム５が貼合されている。 1 is a support, and on the support 1 is an adhesive layer 2.
A porous thin paper 3 is pasted thereon, and a stretched thermoplastic synthetic resin film 5 is further pasted thereon through an adhesive layer 4.
前記支持体１としては、紙またはプラスチツク
フイルムが使用できるが、好ましくは坪量60〜
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.

溶融樹脂分を吸収可能なものから構成されたもの
を用いることができる。 A porous thin paper 3 is laminated onto the support 1 via an adhesive layer 2. This porous thin paper 3 may be made of, for example, synthetic fibers such as polyester fibers, vinylon fibers, and nylon fibers, each having a fineness of 3 deniers or less, or natural fibers such as manila hemp, mulberry, mitsumata, pulp, etc. alone or in mixtures, and other thermal fibers described below. A film made of a plastic synthetic resin film that can absorb the molten resin can be used.

印刷ができない。 The porous thin paper 3 has a basis weight of 6 to 15.
g/ m2 , especially 8~12g/ m2 , thickness 20~
It is preferably 70μ, especially 25 to 50μ.
The thickness of porous tissue paper is less than 20μ or the basis weight is 6
If it is less than g/m 2 , it is difficult for the resin of the film melted by the thermal head during plate-making to be impregnated into and absorbed into the thin paper. On the other hand, if the thickness of the porous thin paper exceeds 70 μm or the basis weight exceeds 15 g/m 2 , the amount of ink absorbed in the image area during printing will be too large, making it impossible to print clearly.

ましい。 A stretched synthetic resin film 5 having a thickness of 0.5 to 5 μm is laminated onto the porous thin paper 3 via an adhesive layer 4. Examples of synthetic resin films include polyester film, polycarbonate film, vinyl chloride resin film, vinylidene chloride resin film, vinylidene fluoride resin film, tetrafluoroethylene resin film, silicone resin film, etc. In particular, polyester film, vinylidene fluoride resin film, etc. A resin film is 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.
接着剤層４の接着剤としては、たとえば前記接

接着剤に用いる溶剤としては合成樹脂フイルムを
溶解または膨潤しないものが好ましい。 As the adhesive for the adhesive layer 4, for example, the adhesive used for forming the adhesive layer 2 can be used. The solvent used for this adhesive is preferably one that does not dissolve or swell the synthetic resin film.

原版として使用できる。 In the present invention, the synthetic resin film 5 may be a vinylidene fluoride resin film, a tetrafluoroethylene resin film, or
When a silicone resin film itself has oil repellency, the sheet-like material having the above structure can be used as it is as an original.
前記合成樹脂フイルム５が撥油性を有さないか
もしくは撥油性に劣るばあいは、さらにそのうえ
に撥油層を設ける。 If the synthetic resin film 5 does not have oil repellency or has poor oil repellency, an oil repellent layer is further provided thereon.
第２図はこの態様の一実施例を示すものであ
り、合成樹脂フイルム５のうえに撥油層６が設け
られている。 FIG. 2 shows an embodiment of this aspect, in which an oil-repellent layer 6 is provided on a synthetic resin film 5.

いと、未塗布部分が発生しやすく好ましくない。
一方塗布量が３ｇ／m2を超えると塗膜が厚くな
り、サーマルヘツドによる合成樹脂フイルムの溶
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 likely 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
と合成樹脂フイルムの融着を防止する効果があ
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
ヘツドを有するサーマルプリンターなどに装着し
て製版する。 The heat-sensitive lithographic printing original plate having the above-mentioned structure is attached to a thermal printer having a thermal head and plate-making is carried out.

のまま残つており、非画像部９を構成する。 Figure 3 shows the state during plate making. In FIG. 3, 7 is a thermal head, and a synthetic resin film 5 (or oil-repellent layer 6, if there is an oil-repellent layer 6) in a portion of the thermal head 7 corresponding to the energized heating element.
) are melted to form a hole, which becomes the image area 8. The portion that is not melted remains oil repellent and constitutes a non-image portion 9.

刷物にはその影響が少なくなるなどの利点があ
る。 Further, in the present invention, during melt plate making by the thermal head 7, the molten material such as the synthetic resin film 5 is absorbed into the porous thin paper 3. This improves plate-making properties, and also allows for a third
As shown in the figure, ink 10 is applied to porous tissue paper 3.
Since the ink is also retained and stored in the ink layer, there is an advantage that even if there is an uneven supply of ink from the offset ink roller, the effect on the printed matter is lessened.
かくしてえられた平版を用い平版印刷機にて印
刷すると、湿し水が無くても非画像部９にインク

ることができる。その理由は、非画像部９は撥油
性であるためインクが付着することがなく、一方
画像部８においては撥油部分が融けているため
に、撥油効果が無く、インクが良好に付着するた
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 9 even without dampening water, and a printed matter with very little scumming can be obtained. The reason for this is that the non-image area 9 is oil-repellent, so ink does not stick to it, while in the image area 8, the oil-repellent part is melted, so there is no oil-repellent effect and ink sticks well. It's for a reason.
