Description

著色感光性樹脂組合物 Colored photosensitive resin composition

本發明涉及一種著色感光性樹脂組合物。 The present invention relates to a colored photosensitive resin composition.

在常規的液晶顯示器中，已經使用具有預定直徑的矽珠或塑膠珠來保持上基板和下基板之間的預定間距。然而，這些珠被隨機地分散在基板上並因此可能位於圖元中的情況是有問題的，因為孔徑(aperture)可能會減小並且可能發生漏光。 In a conventional liquid crystal display, bead beads or plastic beads having a predetermined diameter have been used to maintain a predetermined spacing between the upper substrate and the lower substrate. However, the fact that these beads are randomly dispersed on the substrate and thus may be located in the primitive is problematic because the aperture may be reduced and light leakage may occur.

以解決這些問題為目標，通過光刻法形成的隔離物已經開始在液晶顯示器中使用。目前，在大多數的液晶顯示器中使用的隔離物是通過光刻法形成。 In order to solve these problems, spacers formed by photolithography have begun to be used in liquid crystal displays. Currently, spacers used in most liquid crystal displays are formed by photolithography.

通過光刻法形成隔離物是通過將著色感光性樹脂組合物塗在基板上、經由光掩模將UV照射到基板上，並使用顯影過程根據掩模的圖案在基板上所需要的位置處形成隔離物。因此，在形成隔離物之後顯影殘渣或污垢可能留在未被UV照射的基板的部分上的情況中，可能引起排列型液晶顯示器的非均一性。 The spacer is formed by photolithography by applying a colored photosensitive resin composition onto a substrate, irradiating UV onto the substrate via a photomask, and forming a desired position on the substrate according to a pattern of the mask using a developing process. Separator. Therefore, in the case where the development residue or the dirt may remain on the portion of the substrate which is not irradiated with UV after the formation of the spacer, the non-uniformity of the alignment type liquid crystal display may be caused.

同時，隨著生產率提高的最近趨勢，製造液晶顯示器時，引入稱為ODF(液晶預滴(One Drop Fill))的工藝，該工藝在黏合液晶面板的玻璃之前，允許液晶材料在玻璃的表面上流動。通過此方法，可顯著地縮短製造液晶顯示器所需的時間段。 Meanwhile, with the recent trend of productivity improvement, when manufacturing a liquid crystal display, a process called ODF (One Drop Fill) is introduced, which allows the liquid crystal material to be on the surface of the glass before bonding the glass of the liquid crystal panel. flow. By this method, the period of time required to manufacture the liquid crystal display can be significantly shortened.

當常規黏合TFT陣列和彩色濾光片時，使用黏合負載，由此隔離物被負載均勻地按壓從而保持隔離物的高度均一。然而，在ODF中，因為初始黏合僅通過基於基板重量和大氣壓的負載而進行，所以初始黏合負載比常規方法的負載小。即使當隔離物被低 負載按壓時，隔離物被均勻地按壓以確保高度均一也是很重要的。當隔離物具有非均一的高度時，不能保持晶胞間距的均一性並因此可能產生在晶胞內的間隙，不希望地造成非均勻顯示。因此，需要具有柔性和高彈性模量的隔離物以實現優異的高度均一性。 When the TFT array and the color filter are conventionally bonded, a bonding load is used, whereby the spacer is uniformly pressed by the load to keep the height of the spacer uniform. However, in the ODF, since the initial bonding is performed only by the load based on the weight of the substrate and the atmospheric pressure, the initial bonding load is smaller than that of the conventional method. Even when the spacer is low When the load is pressed, it is also important that the spacer is uniformly pressed to ensure uniformity of height. When the spacers have a non-uniform height, the uniformity of the cell pitch cannot be maintained and thus a gap within the unit cell may be generated, undesirably causing non-uniform display. Therefore, a separator having flexibility and high modulus of elasticity is required to achieve excellent height uniformity.

為此，通過加入具有光固化性鹼溶性(共)聚物的常規的著色感光性樹脂組合物，已經嘗試使用樹脂組合物。韓國專利申請公開號10-2010-0060562公開了一種鹼溶性樹脂，包括，具有不飽和雙鍵的單體、具有環氧基的單體和具有長側鏈和酸性基團的單體作為重複單元的反應產物；但它是有問題的，因為低的顯影速率、低的敏感度和差的附著力，不希望地引起圖案分離。 For this reason, a resin composition has been attempted by adding a conventional colored photosensitive resin composition having a photocurable alkali-soluble (co)polymer. Korean Patent Application Publication No. 10-2010-0060562 discloses an alkali-soluble resin comprising a monomer having an unsaturated double bond, a monomer having an epoxy group, and a monomer having a long side chain and an acidic group as a repeating unit. The reaction product; however, it is problematic because of the low development rate, low sensitivity and poor adhesion, which undesirably causes pattern separation.

因此，本發明的目的是提供一種著色感光性樹脂組合物，其具有高的顯影速率與優異的敏感度和附著力，並因此在顯影過程中沒有圖案的分離，並且當該著色感光性樹脂組合物被應用為用於平板顯示器的光刻材料(諸如柱狀隔離物、彩色濾光片、彩色光阻劑等)時，它也可以表現出高的顯影性與優異的敏感度和附著力，使得在顯影過程中難以產生圖案的短路，從而提高彩色濾光片的生產率，其中，使用該組合物製造的彩色濾光片在包括對比度、透光率、耐化學品性和敏感度的性質方面均被提高。 Accordingly, an object of the present invention is to provide a colored photosensitive resin composition which has a high development rate and excellent sensitivity and adhesion, and thus has no pattern separation during development, and when the colored photosensitive resin is combined When applied as a lithographic material for a flat panel display (such as a column spacer, a color filter, a color photoresist, etc.), it can also exhibit high developability and excellent sensitivity and adhesion. It is difficult to generate a short circuit of the pattern during development, thereby improving the productivity of the color filter, wherein the color filter manufactured using the composition has properties including contrast, light transmittance, chemical resistance, and sensitivity. Both have been improved.

這些染料可以單獨使用或以兩種或更多種的組合使用。 These dyes may be used singly or in combination of two or more.

基於著色劑(A)的固含量的總重量，著色劑(A)的染料的量優選為0.5~80wt%，更優選為0.5~60wt%，進一步優選為1~50wt%。當著色劑(A)的染料的量落入基於前述的上述範圍內時，可以防止在圖案形成之後發生的由於染料在有機溶劑中溶解而導致的可靠性惡化的問題，並可以產生高敏感度。 The amount of the dye of the colorant (A) is preferably from 0.5 to 80% by weight, more preferably from 0.5 to 60% by weight, still more preferably from 1 to 50% by weight, based on the total weight of the solid content of the colorant (A). When the amount of the dye of the colorant (A) falls within the above range based on the foregoing, the problem of deterioration in reliability due to dissolution of the dye in the organic solvent which occurs after pattern formation can be prevented, and high sensitivity can be produced. .

基於著色感光性樹脂組合物的固含量的重量，著色劑(A)的量被設定為5~60wt%，優選設定為10~45wt%。著色劑(A)的用量為基於前述的5~60wt%的情況是可取的，因為即使在形成薄膜時圖元部分也具有充分的顏色濃度，並且在顯影時不降低非圖元部分的脫落，有利地使得難以產生殘留。 The amount of the colorant (A) is set to 5 to 60% by weight, preferably 10 to 45% by weight, based on the weight of the solid content of the colored photosensitive resin composition. It is preferable that the amount of the coloring agent (A) is 5 to 60% by weight based on the foregoing, because the element portion has a sufficient color concentration even when the film is formed, and does not reduce the peeling of the non-primitive portion during development, Advantageously, it is difficult to create a residue.

根據本發明的鹼溶性樹脂(B)的酸值為30~150mgKOH/g，以確保著色感光性樹脂組合物的相容性和貯存穩定性。如果鹼溶性樹脂的酸值小於30mgKOH/g，那麼著色感光性樹脂組合物難以確保充分的顯影速率。與此相反，如果其酸值高於150mgKOH/g，那麼對基板的附著力降低，使得易於產生圖案的短路，以及引起與相容性和貯存穩定性有關的問題，不希望地增加黏度。 The alkali-soluble resin (B) according to the present invention has an acid value of 30 to 150 mgKOH/g to ensure compatibility and storage stability of the colored photosensitive resin composition. If the acid value of the alkali-soluble resin is less than 30 mgKOH/g, it is difficult to ensure a sufficient development rate of the colored photosensitive resin composition. In contrast, if the acid value is higher than 150 mgKOH/g, the adhesion to the substrate is lowered, so that a short circuit of the pattern is liable to occur, and problems associated with compatibility and storage stability are caused, and the viscosity is undesirably increased.
