Description of the Related Art When a printing plate is classified by a printing method, it is roughly classified into a letterpress printing plate, a planographic printing plate used for offset printing, an intaglio printing plate represented by gravure printing, and a screen printing plate. . These printing methods are selectively used according to the type of printed material, print quality, the number of prints, or the management policy and constitution of the printing company. Among them, the offset printing field is expanding and diversifying in the fields of general commercial printing, newspaper printing, packaging material printing, etc. against the backdrop of rapid advances in photoengraving system technology and photosensitive material technology. It has reached over 80%.

にくい。In offset printing, conventionally, a printing plate material (referred to as a PS plate) mainly made of aluminum and coated with a photosensitizer is used.
Is used. The PS plate is produced by exposing the plate surface to actinic rays emitted from a mercury discharge lamp or a laser through a photographic film for plate making having printing image information, and then removing the photosensitive agent in the unexposed area or exposed area with a developing solution. (It is called development.) Then, the printing image is formed and the printing plate is produced, and it meets the requirements of the plate-making industry such as reduction of plate-making cost, shortening of plate-making time, and reduction of processing load of developing waste liquid. Is hard to handle.

It is not impossible to make a PS plate using this system, but there are problems due to low sensitivity, that is, it takes a long time to make a plate and deterioration of plate making quality is unavoidable.

なり、ダイレクト印刷の手軽さが損なわれる。However, the inventors of the present invention thought that the method of separating hydrophobicity and hydrophilicity shown in these two documents was very interesting, but it was difficult to apply it to lithographic printing.
The reason is that, although laser printing can show hydrophilicity, lithographic printing is not only hydrophilic, but many printings are not possible without hydrophilicity and water retention. In the above literature, the depth of corrosion obtained by laser irradiation is around 1 μm, so it is unlikely to have sufficient water retention. Further, in order to increase the water retention property, it is possible to further perform ablation to increase the corrosion depth, but in that case, the required energy becomes several J / cm 2 , and the convenience of direct printing is impaired.

It was found that it has water retention as well as hydrophilicity. This is very surprising. The reason for this is still under investigation and is often unknown, but it is presumed that it is because the polymer surface becomes porous. The present invention

It has effects such as cleanliness and elimination of fear of material supply. That is, by irradiating a high-Tg, high-absorptive thermoplastic polymer film having an absorption band in the ultraviolet region with an ultraviolet pulse laser having oscillation energy in that region, the hydrophilicity of the surface to be irradiated is increased, It expresses selective adhesiveness.

Anything above can be used. Specifically, polyimide resin, polyphenylquinosaline (PPQ), polysulfone,
Alternatively, a polymer having these skeletons in the molecule is preferable. Among the polyimide resins, a film obtained by polycondensation, for example, a Kapton film manufactured by DuPont (US) is more preferable. The film thickness can be set arbitrarily, but a film thickness of 50 μm or more is preferable in order to satisfy the mechanical strength and physical requirements required for the printing plate. The film becomes a printing plate by itself as described above, but if necessary, it is thermoplastic on a support (e.g., various plastic sheets with good dimensional stability, paper, a metal plate alone or a composite plate bonded together). A film layer may be formed.

ればならない。The laser serving as a light source is a pulsed UV laser, a multimode Nd: YAG laser (the fourth synchronous mode 266 nm and the third synchronous mode 358 nm), Ar.
An F (oscillation wavelength 193 nm) excimer laser, a KrF (oscillation wavelength 248 nm), and a XeCl (oscillation wavelength 308 nm) excimer laser can be used. From the viewpoint of easy maintenance, the YAG laser is preferable to the excimer laser. The energy density (fluence) required to increase hydrophilicity is in the range of 10 to 100 mJ / cm 2 . 10
When it exceeds 0 mJ / cm 2 , ablation becomes severe and the surface roughness increases, but it is not useful for improving printability. In order to impart hydrophilicity to the surface to be irradiated, there is a threshold of energy density. Therefore, a pulse with a large peak output is required due to a short intense pulse discharge. Irradiation with a continuous excitation oscillation type laser or mercury lamp light cannot enhance the hydrophilicity. In order to absorb energy efficiently, the absorbance of the film is 1 × 10 2 c
It must be at least m −1 , preferably 5 × 10 2 to 5 × 10 3 cm −1 .

せている。Whether the laser irradiation is carried out in the air, in water or in an alkaline solution such as tetramethylammonium hydroxide, the hydrophilicity can be enhanced. Hydrophilicity can be represented by a change in contact angle with water. 40 mJ / cm
When the laser irradiation of 2 is performed, the contact angle with water changes in the range of 80 degrees to 0 degrees. In the printing industry, it is said that offset printing is possible if the contact angle of the printing plate with water is 20 degrees or less. The products of the present invention all satisfy this value.

Kapton becomes higher in the order of PPQ. Polycarbonate,
Polystyrene and polymethylmethacrylate show almost no hydrophilicity. It can be seen that the hydrophilicity of these polymers decreases with decreasing Tg. It is considered that the hydrophilicity is due to ablation caused by laser irradiation, porosity of the irradiated site, generation of positive charge on the surface, and increase in surface roughness. It is considered that when Tg is high, the porous structure and surface roughness of the surface portion generated by irradiation can be maintained. In order to develop hydrophilicity and maintain for a long time,
The Tg of the polymer must be at least 160 ° C or above. The hydrophilicity of the irradiated area can be maintained for at least several months, but the hydrophilicity must be maintained semipermanently for practical use as a printing plate. For that purpose, the conventional desensitizing method containing phosphoric acid as a main component can be applied as it is.
