Problems solved by technology

Electrophotography has problems such as the process of forming an electrostatic latent image on the photoreceptor drum through charging and exposure, which complicates the system and results in high manufacturing costs.
In addition, although the thermal transfer method is inexpensive, it has problems such as high running costs and waste due to the use of ink ribbons.

Embodiment 1

[0472]The prepared primer P1 was filled in a UV inkjet printer Acuity LED1600 manufactured by Fujifilm Corporation. As the ink, Uvijet LL ink (ultraviolet curable ink composition, cyan, magenta, yellow, black, light cyan, light magenta, and white colors) manufactured by Fujifilm Co., Ltd. was used. Using glass (manufactured by Asahi Glass Co., Ltd., TEMPERLITE) as the recording medium, print a primer layer between the recording medium and the test image in high-resolution mode by printing separately, or print a white solid on a part of the test image image. Then, evaluation of curability, initial stage adhesiveness, and weather resistance was performed using the obtained printed matter by the following reference|standard. The results are shown in Table 2.

Embodiment 2～7 and comparative example 1～3

[0474] In Example 1, as shown in Table 2, primers P2 to P7, CP1 or CP2 were used instead of primer P1, or no primer was used, and printed matter was produced in the same manner as in Example 1 except that , curability, initial adhesiveness, and weather resistance were evaluated using the obtained printed matter. The results are shown in Table 2.

[0475]

[0476] Regarding curability, the stickiness of the surface of the printed matter based on the touch of each ink 100% concentration part and the presence or absence of transfer in the image part when the printed matter was stacked and left for 1 day (at 25° C.) were evaluated according to the following criteria.

[0477] 0: There is no stickiness at all on the surface of the printed matter, and there is no transfer.

[0478] 1: There is slight stickiness on the surface of the printed matter, but no transfer.

[0479] 2: There is stickiness on the surface of the printed matter, and transfer occurs slightly.

[0496] In Examples 1-7 and Comparative Examples 1-3, except having used the LL ink which added the ultraviolet absorber instead of LL ink, it carried out similarly to Examples 1-7 and Comparative Examples 1-3, and produced the printed matter. Then, curability, initial stage adhesiveness, temporal adhesiveness, and weather resistance were evaluated using the obtained printed matter. The results are shown in Table 3.

[0498]

[0499] (Preparation of primers P8~P11 and CP3)

[0500] The following components were stirred at 2,500 rpm for 15 minutes using a stirrer (L4R manufactured by Silverson Corporation). Thereafter, the resulting mixture was filtered using a cartridge filter (product name Profile IIAB01A01014J) manufactured by Nippon Pall Corporation to obtain primers P8 to P11 and CP3, respectively. In addition, the addition amount of TATZ-1 is shown in Table 4.

Abstract

The present invention provides an inkjet recording method, which is characterized in that it includes spraying an ultraviolet curable ink composition onto a primer layer formed on at least a part of the surface of a transparent recording medium by an inkjet method. and a curing step of curing the ink composition by irradiating ultraviolet rays to the ejected ink composition; the primer layer contains a compound selected from triaryl triazine compounds and benzoxazinone compounds. , a benzoxazole-based compound, a benzophenone-based compound, and a cyanoacrylate-based compound and at least one ultraviolet absorber selected from the group consisting of.

Description

technical field [0001] The present invention relates to an inkjet recording method. Background technique [0002] As an image recording method for forming an image on a recording medium such as paper based on an image data signal, there are an electrophotographic method, a sublimation type and a fusion type thermal transfer method, an inkjet method, and the like. In the electrophotographic method, there are problems that the process of forming an electrostatic latent image on the photoreceptor drum by charging and exposing is required, the system becomes complicated, and the manufacturing cost becomes high as a result. In addition, the thermal transfer method has problems such as high running costs and waste due to the use of an ink ribbon, although the equipment is cheap. [0003] On the other hand, the inkjet method uses an inexpensive device and ejects ink only to a necessary image portion to form an image directly on a recording medium, so the ink can be used efficientl...
