Field of the Invention The present invention relates to a photocurable inkjet ink which can be preferably used for manufacturing an optical device such as an image display device. More specifically, the present invention relates to a photocurable inkjet ink suitable for the production of an optical component having a microlens used in a backlight unit. [Prior Art] Since the prior art, the microlens formed on the light guide plate for an image display device has been formed by injection molding using a mold. The method is a method that requires a mold each time the article is designed, and is very costly when manufacturing a small number of types of microlenses. In recent years, a method of forming a microlens on the surface of a substrate by an inkjet method has been proposed as a manufacturing method which is inexpensive and has a high degree of freedom in design. However, the microlens formed using the previous composition has a large variation in pattern size and pattern height. problem. In order to improve this problem, it has been proposed to perform a liquid-repellent treatment on the surface of the substrate by an ink-jet method. In the liquid-repellent treatment, a negative-type photosensitive composition capable of forming a surface liquid-repellent cured film can be used (for example, see JP-A-2008-209739).

[Embodiment] Photocurable inkjet ink] The leveling of the present invention, The ink ink (the ink of the present invention) includes an organic solvent (A) having at least one selected from the group consisting of a cycloalkyl group and a cycloalkane, and having no amine bismuth citrate bond. The functional (meth)acrylic acid g (8), the surfactant (6), and the photopolymerization initiator (D)' are chopped with respect to the photocurable inkjet ink. The above solvent (Α)β-▲ is contained in an amount of 40% by weight to 98% by weight. The ink of the present invention contains the above-mentioned specific amount of an organic solvent (Λ), a polyfunctional (fluorenyl) acrylate (8), and a surfactant (c). And the photopolymerization initiator (D) is excellent in wet diffusion of the substrate such as an acrylic resin substrate, and the ink is applied onto a substrate such as an acrylic resin substrate by an inkjet method, and is cured. On the other hand, a surface liquid-repellent cured film having a small film thickness can be easily formed. Further, when a microlens is formed on the surface liquid-repellent cured film obtained from the ink of the present invention by the ink-jet method, a microlens having a small deviation between the pattern diameter and the directionality can be easily formed. The ink of the present invention may optionally contain a polymerization inhibitor, a thermosetting compound other than an epoxy compound, a flame retardant, a thermal polymerization initiator, an ultraviolet absorber, an antioxidant, and the like, within the scope of the gist of the present invention. Other components such as a decane coupling agent, (meth)acrylic acid urethane (E), and/or polyglycol (meth) acrylate (B) and (meth) acrylate urethane ( A radically polymerizable compound (F) other than E). The ink of the present invention may be colorless or colored. In view of the light transmittance, colorless is preferable, but in the range which does not impair the effects of the invention, 201250388 may also contain a colored compound. For example, when the state of the cured film is examined, a coloring agent may be contained in order to easily distinguish it from the substrate.

當藉由喷墨法來形成膜厚薄的表面撥液性硬化膜時，墨水的著滴直徑（點直徑）及其高度（點高度）極其重要。一般認為隨著點直徑的值變大，對於基板的潤濕擴散大，即便將印刷的解析度設定得低，亦可形成均句的'膜，而成為可獲得膜厚薄的硬化膜的指標。另外，點高度亦成為表示值變得越小，越可獲得膜厚薄的硬化臈的指標。當藉由喷墨法來形成膜厚薄的表面撥液性硬化膜時，較佳為同時滿足兩者。 # 已確認與比較例1、比較例2的墨水9、墨水1〇相比，含有多官能（曱基)丙烯酸酯（Β )的實例1〜實例8的黑水 1〜墨水8對於丙烯酸樹脂基板顯現非常高的濕潤性二另外，已確認尤其墨水i、墨水2及墨水4對於丙烯酸樹脂基板顯現非常高的濕潤性。根據實例1〜實例8與參考的結果而確認，藉由使用含有特定量的溶劑的墨水，可带成點直徑大、點高度低的點圖案，因此該墨水對於美板^ 47When a thin surface liquid-repellent cured film having a thin film thickness is formed by an inkjet method, the droplet diameter (dot diameter) of the ink and its height (dot height) are extremely important. It is considered that as the value of the dot diameter becomes larger, the wetting diffusion to the substrate is large, and even if the resolution of printing is set to be low, a film of a uniform sentence can be formed, and an index of a cured film having a small film thickness can be obtained. Further, the dot height is also an index indicating that the smaller the value becomes, the harder the film thickness can be obtained. When the surface liquid-repellent cured film having a small film thickness is formed by an ink-jet method, it is preferable to satisfy both of them at the same time. # It was confirmed that the black water 1 to ink 8 of Examples 1 to 8 containing polyfunctional (fluorenyl) acrylate (Β) were compared with the ink 9 of the comparative example 1, the comparative example 2, and the ink 1 对于 for the acrylic resin substrate.

Therefore, even if the resolution of printing on the substrate is low on the substrate, the film can be obtained when the film of the substrate is obtained. Therefore, it is possible to make a uniform surface repellency with respect to the surface liquid-repellent cured film. The wet and diffuse diffusibility of the lipid substrate is poor. In the case of the substrate, especially the pro-glycoprotein tree, the resolution of the right printing is not high, so it is difficult to correct the period: 2012 20128388 42579pifl Revision period: August 24, 2011 is the Chinese manual No. 10112〇389 Since there is no scribe line correction, a film such as a cover substrate is formed. Therefore, in many cases, only a film having a thick film thickness which is easy to be colored can be formed. The surface liquid-repellent cured film of the present invention can be preferably used for the manufacture of a microlens used in a backlight unit or the like because it can realize thinning and exhibits high light transmittance and high strength. Preferably, the formation of a liquid-repellent film provided on the surface of the substrate at the time of manufacturing the microlens array is preferred. [5. Microlens] The microlens of the present invention is formed by the inkjet method in the above-described present invention.

The surface is dialed on the hardened film. Therefore, a microlens having a small deviation in the diameter and height of the pattern can be easily formed. When the microlens is formed, the ink for forming a microlens can be used as the ink, and the ink is known. Further, the method of forming the microlens is not limited, and may be appropriately adjusted in accordance with the ink to be used. 'The lens diameter of the above microlens is not particularly limited, and is usually preferably from ηηι to 100哗, more preferably from 15 _ to 6 〇, and particularly preferably from 2 〇 to 5 〇〇, the height of the lens is not particularly limited, and usually Preferably, 〇~3〇'' is preferably 1μιη~20μιη, especially good for 2_~1〇 handsome. The ratio of the height of the mirror to the diameter of the lens is not particularly limited, but it is preferably 0.18 or more and more preferably 0.2 or more in terms of a light material capable of producing a fresh extraction efficiency (IV).
