The sockets 151, 152 insulate the sealed leads 161, 1 62. A lead circuit 161 is connected to a power supply circuit (not shown). In the airtight container 11, as an enclosure, argon gas necessary for maintaining an arc discharge is sealed at 丨3 kPa, and iron, Hg (mercury) or the like of a metal for emitting ultraviolet rays is sealed. The metal-based lamp thus constituted can be irradiated with ultraviolet rays by iron of a luminescent metal having a spectral characteristic in an ultraviolet region. The ultraviolet curable resin composition irradiated with the ultraviolet ray contains a photoinitiator which starts polymerization of the polymerizable resin of the resin composition by irradiation with the ultraviolet ray.

Here, (4) ~ (g) of the photoinitiator, using at least in the wavelength range of 350 ~ 380 nm for The photoinitiators (a) and (g)e having a high absorption ratio of the emission wavelength are described below. The outer diameter of the airtight container u is small, the wall thickness is 145812.doc 201039372, and the length is 1.5 mm. In a lamp composed of a 1000 mm single-layer tube, the enclosed luminescent metal is compared with an embodiment of the present invention in which a snake is enclosed as a luminescent metal, and is generated to accelerate at least 350 to 380 nm. The long-wavelength ultraviolet ray has an embodiment of the present invention which absorbs ultraviolet light at a rate of polymerization of a photoinitiator in a wavelength region. Further, it is caused by light in the following embodiments. A comparison with the previous case of (4) 4,4'-bis(diethylamino)benzophenone irradiation of ultraviolet light of an iron-based metal lamp was carried out. (Example 1) In Example 1, a lanthanide system was prepared. The metal-based lamp is enclosed in an airtight container 11 as an enclosure to enclose an iodide of 1.3 kPa of argon gas, mercury, and a metal for emitting ultraviolet light, which is necessary for maintaining the arc discharge. The ultraviolet light emitted from the bismuth metal halide lamp and the ultraviolet ray emitted from the iron metal dentate lamp which is sealed with iron as a metal for illuminating the outer line of the rabbit, and the photoinitiator contained in the curable resin composition. The effect of diethylamino)benzophenone is described. Here, it is considered that the input voltage of the same grade of 12000 w and the lamp voltage of 11 〇〇v for the bismuth metal halide lamp and the ferrous metal lamp are respectively And the case where the lamp current of 10.9 A is irradiated with ultraviolet rays. Fig. 4 shows the respective spectral distributions and amounts of light of the lanthanide metal halide lamp and the iron-based metal halide lamp of the present invention. As is apparent from Fig. 4, 'for the resin composition Necessary to harden the photoinitiator contained 3 50~3 80 nm long-wavelength ultraviolet light, superior to snake metal halide lamps. Figure 5 is only a magnified display of the photoinitiator 4,4,_ double (diethyl 145812.doc 201039372 amino) diphenyl The absorption rate of the ketone light emission wavelength. When the luminescence spectrum curve of the metal halide lamp is α(λ) and the absorption spectrum curve of the photoinitiator is Φ(λ), the reaction between the lamp and the photoinitiator is used. As shown in Fig. 5, a represents the lower wavelength of the luminescence spectrum, and b represents the higher wavelength of the luminescence spectrum. [Number 1] £ α (顾 > 1) = Σ α (柳U) 〇 3 Here, when the wavelength of the luminescence spectrum is &lt; 350 nm and the wavelength is bg380 nm, the ratio of the effect of the photoinitiator of the lanthanide metal halide lamp and the iron-based metal halide lamp is compared, and the result shown in Fig. 6 is obtained. . That is, when the iron-based metal halide lamp is 1% by weight, the lanthanum metal halide lamp is 112/. This shows that when the curable resin composition containing the photoinitiator 4,4'-bis(diethylamino)benzophenone is irradiated with ultraviolet rays of a lanthanoid metal lamp, the curing rate is increased by 12%. In the embodiment, if the ultraviolet ray of the lanthanide metal gutta lamp is irradiated to the photoinitiator having an absorption wavelength region between 350 nm and nm, the photoinitiator may be irradiated with the ultraviolet ray of the urethane lamp. In the case of the luminescence efficiency, the hardening speed of the curable resin composition can be increased. • In Example 1, the lamp containing cesium iodide was used as an example. However, it is not limited to moth compounds, and the same effect can be obtained by sealing with other tooth compounds. Namely, it is also possible to easily enclose a compound which is evaporated in an airtight container in the electric cell discharge (Example 2). Next, an embodiment of the present invention 145812.doc 201039372 2 will be described with reference to Figs. Fig. 7 and Fig. 8 show the relationship between the splitting of the metal halide lamp and the illuminance of the metal halide lamp when the amount of each cesium iodide is different in the lamp having a light emission length of 1 〇〇〇 mm. the result of. Fig. 7 shows the case where the encapsulation amount of cesium iodide is 0.040 mg/cc, and Fig. 8 shows the case where the encapsulation amount of cesium iodide is 0.036 mg/cc. In the case where the amount of cesium iodide enclosed in Fig. 7 is 〇 4 〇 mg/cc, ultraviolet light is emitted in the axial direction, and the split light distribution is caused to be different, which may adversely affect the object to be irradiated. The problem caused by the separation luminescence is particularly remarkable in lamps having a light emission length of 200 mm or more. The difference in the distribution of the light distribution between the left and right is believed to be due to the difference in the saturated vapor pressure of cesium iodide, which causes Wei Ming to differ from the bulb, so that the difference between the left and right sputum is revealed as the difference in the spectral distribution. In the case where the amount of the dished snake is 〇〇36 mg/cc, the ultraviolet ray is not observed in the axial direction, but the left and right splitting is the same knives. Uniformity of the uniformity. Therefore, by obtaining a high uniformity on the left and right, the hard 'speed of the curable resin composition can be improved. Figure 9 is a comparison between the use of an iron metal lamp and the m-halogen of the embodiment, and the photoinitiator 4,4,-bis (di[amino])benza is irradiated with ultraviolet rays. , an explanatory diagram for explanation. 2, when the encapsulation amount of cesium iodide is 0.01 mg/cc or more, the curing time by the implementation of the shape of the bismuth i lamp is relatively 1% or more with respect to the utilization time of the iron-based metal lamp. When the impulse is 〇〇〇6 or less, the hardening time of the metal-based lamp with the real % form is shorter than the hardening time of the metal illuminator with the iron 145812.doc 201039372. However, when #魏(四) is above gg4, although the hardening time is increased, as mentioned above, there is a problem that the luminescent separation is fast or slow. Therefore, it is known that when the amount of cesium iodide contained in the bismuth metal dentate lamp irradiated with ultraviolet light by the light-induced bismuth (diethylamino) benzophenone is 0.01 to 〇 ton, and the use of iron Advantageous results can be obtained compared to the case of metal pygmy lamps. Ο $®10 is used for the hardening time of the photoinitiator 4,4 bis (di-amino-amino)diphenyl fluorene when the ultraviolet ray is irradiated with an iron-based metal halide lamp and an embodiment of the genus metal-tooth lamp. For comparison, explain the explanation. In this case, when the encapsulation amount of the moth hall is 0.006 mg/cc or more, the hardening time of the metal element lamp using the embodiment is 101% ± with respect to the hardening time of the iron-based metal tooth lamp. When the amount of sputum is 〇〇〇2 mg/cc or less, the hardening time of the metal dentate lamp using the embodiment is shorter than the hardening time by the ferrous metal halide lamp. However, when the dry amount of the filling is © 〇.〇4 mg/cc or more, the curing time is increased, but the luminescence separation occurs, so that the hardening time is fast or slow. Therefore, it is known that when the photoinitiator 4,4,_bis(dimethylamino)dibenzophenone is irradiated with ultraviolet rays, the amount of cesium iodide is •·〇〇6~0.036 mg. When /cc is used, advantageous results can be obtained as compared with the case of using an iron-based metal halide lamp. From this, it is understood that the hardening rate of the curable resin composition having a high ultraviolet absorption rate at a long wavelength of 350 to 380 nm cannot be increased irrespective of the amount of cesium iodide enclosed. 145812.doc 201039372 Therefore, as a condition for increasing the curing rate of a curable resin composition having a high absorption rate at 350 to 380 nm, the amount of xenon iodide sealed (X/cc) is 4, 4'-double. In the case where (diethylamino)benzophenone is a photoinitiator, it is in the range of 0.01 to 0.036. It is also known that in the case where 4,4'-bis(diguanidino)benzophenone is a photoinitiator, it is in the range of 〇6 to 〇36. According to the present embodiment, the curing rate of the ultraviolet curable resin composition containing the photoinitiator in the wavelength region of the long wavelength ultraviolet rays of 35 Å to 38 Å nrn can be increased.
