各式は、この代表的な反応である。Photosensitive resins according to the present invention include photochromic materials. This is a material that is easy to handle and whose molecular structure changes reversibly upon irradiation with light without changing its molecular weight, accompanied by a noticeable color change. The formulas in Table 1 below are representative reactions.

界面特性がある。Incidentally, although there are various reaction mechanisms for isomerization reactions, some compounds are known whose polarity changes significantly during structural isomerization. For example, in the azobenzene of formula (I), the dipole moment of the trans form (left side) is 0.5D, whereas the dipole moment of the cis form (right side) increases to 3.1D, and hydrophobicity changes to hydrophobicity. do. Further, when the spirobenzopyran of formula (n) is photoisomerized to the merocyanine type, the polarity changes significantly. An extreme example is the leuco form of triphenylmethane shown in formula (V) described below. Ions of this compound are generated by light irradiation, and nonpolar molecules are converted into ions. When these organic molecules are introduced into polymer side chains or main chains through chemical bonds, various physical properties of the polymers are reversibly changed by light irradiation. One of these is interfacial properties.

、利用法も異なる。The azobenzene group contained in the azobenzene of formula (I) undergoes structural isomerization from the trans form to the cis form upon irradiation with ultraviolet rays. FIG. 4 shows the correlation between absorption change at 325 nm and surface wettability. From the figure, it can be seen that the 325 nm absorption of the trans isomer decreases due to ultraviolet irradiation, and at the same time, the cosine (Cos θ) of the contact angle with water increases (that is, it becomes hydrophilic). Furthermore, when visible light is irradiated, absorption by the transformer increases again, and COS θ decreases at the same time. One such polymer contains 0-
There is hydroxycarbinol, and R=C of this compound
Although H=CH2 derivatives are synthesized and introduced into polymers by copolymerization, their wettability changes when exposed to light. This copolymer caused a dehydration reaction due to a decrease in the number of OH groups and became water repellent. It exhibits completely different properties from the azobenzene group, and its usage is also different.
本発明によれば、直接製版により版をシリンダに装着す

不゛要となるいわば一工程で製版。According to the present invention, direct plate making eliminates the need to mount the plate in a cylinder, reducing the total operating time of the printing press, and plate making is done in one step, so to speak, with no need for registration.
印刷が可能な印刷方法を提供できる。It is possible to provide a printing method that allows printing.

(Illustrated in FIG. 1(B)). Next, the photoresponsive resin layer 13a
Ultraviolet light was applied to the top (as shown in FIG. 1(C)). the result,
The color of the resin layer 13a changes, and the surface properties change as described above. Next, dampening water 14 is applied on the resin layer 13a.
and ink 15 were supplied separately as in normal offset printing. As a result, water 14 adhered to exposed areas, ink 15 adhered to non-exposed areas, and the other materials adhered in the opposite direction, resulting in development. Furthermore, this was transferred to paper and printing was repeated (first
Figure ('D) shown). In addition, if you repeat this printing, about 10
After 00 sheets, the durability of the resin decreases and printing becomes impossible.

, printing (shown in FIG. 2(C)) is the same as in the first embodiment. After that, instead of changing the plate, visible light 17 was irradiated to the non-printing area on the resin that had lost its hydrophilic properties, and the resin surface, whose surface properties had changed, was returned to its original lipophilic surface (second step).
Figure (E) shown). Next, the new surface is irradiated with ultraviolet rays again (as shown in FIG. 2(F)) to induce strong hydrophilicity. Next, as described above, development and printing (as shown in FIG. 2 ('G)),
It dissolves in a solvent and regenerates into another printable surface. In this way, development, printing, and light irradiation are repeatedly performed (as shown in FIG. 2(H)).

The photoresist film on this surface is partially dissolved, and the aluminum surface, which is the plate base material, is exposed.

Here, the amount of benzene used was (1) 1 Occ/g and (2) 20 cc/g per gram of photosensitive resin, respectively, and coating was carried out by (2) dipping method and (2) roller method. In addition, in order to evaporate the benzene added from the coated surface during drying, it was dried by 1) pulling it in a desiccator with a vacuum pump, and 2) leaving it naturally.

ｍ／ｓで行った。(4) The printing method was carried out as shown in FIGS. 5(A) to (E). That is, as shown in FIG. 5(A), the printing plate 21 is soaked in the bath 22 (or with a rubber roller), and then a certain amount of ink 24 is wrapped around the ink forming roller 23 (see FIG. 5(B). ), the printing plate 21 is passed in a straight line under the roller 23 on which the ink is deposited (as shown in FIG. 5(C)), and then continues under the blanket roller 25 to transfer the transferred ink to the blanket roller 25. Next, the ink attached to the blanket roller 25 is retransferred onto a separately running paper 26 (as shown in FIG. 5(D)), and the process is repeated until the image 27 on the paper surface 26 becomes solid (as shown in FIG. 5(E)). . Here, when the ink was transferred from the ink application roller 23 to the printing plate 21, the ink was not transferred because the exposed areas were hydrophilic and the ink was applied only to the non-exposed areas. The printing conditions are a roller load of 600 Newtons and a printing speed of 0.5
It was performed at m/s.

In this state, the next printing is possible, so ultraviolet light is newly irradiated to create strong hydrophilicity in another location.
