<著色組成物> <Coloring composition>
本發明的著色組成物(以下亦稱為本發明的組成物)含有(A)色素多聚物及(B)溶劑,並且所述著色組成物的特徵在於:(A)色素多聚物具有來源於具有陽離子部位的氧雜蒽色素的部分結構(以下有時稱為「色素結構」)及陰離子部位,且本發明的組成物 中的鈉離子濃度及鉀離子濃度的至少一者為0.1ppm~10ppm。 The coloring composition of the present invention (hereinafter also referred to as a composition of the present invention) contains (A) a dye polymer and (B) a solvent, and the coloring composition is characterized in that (A) the pigment polymer has a source a partial structure of a xanthene dye having a cationic site (hereinafter sometimes referred to as "pigment structure") and an anion site, and the composition of the present invention At least one of the sodium ion concentration and the potassium ion concentration is 0.1 ppm to 10 ppm.
根據本發明,可提供一種於長期(例如1個月以上)放置於低溫度環境下(例如-30℃~0℃)的情形時不易產生異物的著色組成物。 According to the present invention, it is possible to provide a coloring composition which is less likely to generate foreign matter when placed in a low temperature environment (for example, -30 ° C to 0 ° C) for a long period of time (for example, 1 month or longer).
其機制雖為推測,但藉由將鈉離子濃度及鉀離子濃度的至少一者設定為10ppm以下,可抑制色素多聚物中的陽離子、與組成物中的鈉離子及鉀離子的至少一者的離子交換反應,使色素結構與組成物中的其他成分(例如樹脂、單體、溶劑等)的相容性更良好。因此,可更有效地抑制色素結構與組成物中的其他成分的相分離。結果於將長期放置於低溫度環境下(例如冷藏保存狀態)的組成物製膜的情形時,可更有效地抑制異物的產生。 Although it is estimated that at least one of the sodium ion concentration and the potassium ion concentration is 10 ppm or less, at least one of the cation in the dye polymer and the sodium ion and potassium ion in the composition can be suppressed. The ion exchange reaction makes the dye structure more compatible with other components in the composition (for example, resin, monomer, solvent, etc.). Therefore, phase separation of the pigment structure from other components in the composition can be more effectively suppressed. As a result, in the case where the composition is placed in a low temperature environment (for example, in a refrigerated storage state) for a long period of time, the generation of foreign matter can be more effectively suppressed.
另外,藉由將鈉離子濃度及鉀離子濃度的至少一者設定為0.1ppm以上,可抑制色素結構與其他成分的相容性變得過高,結果可更有效地抑制異物的產生。 In addition, by setting at least one of the sodium ion concentration and the potassium ion concentration to 0.1 ppm or more, the compatibility between the dye structure and other components can be suppressed from being excessively high, and as a result, the generation of foreign matter can be more effectively suppressed.
尤其較佳為組成物中的鈉離子濃度及鉀離子濃度分別為1ppm~10ppm,更佳為3ppm~7ppm。藉由調整至此種範圍內,可更有效地達成本發明的效果。 It is particularly preferable that the sodium ion concentration and the potassium ion concentration in the composition are 1 ppm to 10 ppm, and more preferably 3 ppm to 7 ppm. By adjusting to such a range, the effects of the present invention can be more effectively achieved.
本發明的組成物較佳為組成物中的甲苯濃度為1ppm~13ppm,更佳為2ppm~10ppm,進而佳為3ppm~7ppm。藉由將甲苯濃度調整至此種範圍內,於將使用本發明的組成物所形成的著色圖案長時間放置的情形時,可更有效地使圖案的線寬均勻。所謂長時間放置,是指於形成著色圖案時,於使用組成物的 膜的形成後將膜長時間放置直至進行i射線曝光為止。 The composition of the present invention preferably has a toluene concentration in the composition of from 1 ppm to 13 ppm, more preferably from 2 ppm to 10 ppm, even more preferably from 3 ppm to 7 ppm. By adjusting the toluene concentration to such a range, when the colored pattern formed using the composition of the present invention is left for a long period of time, the line width of the pattern can be more effectively made uniform. The so-called long-term placement refers to the use of the composition when forming a colored pattern. After the film is formed, the film is left for a long time until i-ray exposure is performed.
藉由將甲苯濃度設定為13ppm以下,可有效地抑制以下情況:甲苯使組成物中的疏水性成分(例如硬化性化合物等)凝聚至必要程度以上。結果,即便長時間放置亦不引起相分離,可維持圖案的線寬更均勻。 By setting the toluene concentration to 13 ppm or less, it is possible to effectively suppress the condensation of a hydrophobic component (for example, a curable compound) in the composition to a required level or more. As a result, even if it is left for a long time, phase separation is not caused, and the line width of the pattern can be maintained more uniform.
另外,藉由將甲苯濃度設定為1ppm以上,可使色素結構中的陽離子部位、與組成物中的疏水性成分的相容性更良好,即便長時間放置亦不引起相分離,可維持圖案的線寬更均勻。例如即便於將放置時間設定為2天以上、將圖案尺寸設定為1.0μm、且使用1.0質量%的氫氧化四甲基銨作為曝光後的顯影液的情形時,亦可維持圖案的線寬更均勻。 Further, by setting the toluene concentration to 1 ppm or more, the compatibility between the cation site in the dye structure and the hydrophobic component in the composition is further improved, and phase separation is not caused even after standing for a long period of time, and the pattern can be maintained. The line width is more uniform. For example, even when the standing time is set to 2 days or more, the pattern size is set to 1.0 μm, and 1.0% by mass of tetramethylammonium hydroxide is used as the developer after exposure, the line width of the pattern can be maintained. Evenly.
本發明的組成物較佳為組成物中的含水率為0.1質量%~5質量%,更佳為0.1質量%~1質量%,進而佳為0.2質量%~0.5質量%。 The composition of the present invention preferably has a water content of from 0.1% by mass to 5% by mass, more preferably from 0.1% by mass to 1% by mass, even more preferably from 0.2% by mass to 0.5% by mass.
藉由將含水率設定為3質量%以下,可更有效地抑制色素多聚物中的陽離子部位與陰離子部位發生分離的情況。對於以陽離子部位與陰離子部位不易分離的狀態形成的膜而言,於低氧濃度下,經光激發的色素自由基不易被氧捕捉(trap),色素更不易分解。 By setting the water content to 3% by mass or less, it is possible to more effectively suppress the separation of the cation site and the anion site in the dye polymer. In the film formed in a state in which the cationic site and the anion site are not easily separated, the photoexcited dye radical is less likely to be trapped by oxygen at a low oxygen concentration, and the dye is less likely to be decomposed.
另外,藉由將含水率設定為0.1質量%以上,陽離子部位與陰離子部位的距離不會過近,故不易引起光激發時的能量遷移或電子遷移,由此色素更不易分解。結果,即便長期放置於低氧濃度 下亦可維持良好的耐光性。 Further, by setting the water content to 0.1% by mass or more, the distance between the cation site and the anion site is not too close, so that energy migration or electron migration at the time of photoexcitation is less likely to occur, whereby the dye is less likely to be decomposed. As a result, even if placed in a low oxygen concentration for a long time It also maintains good light resistance.
尤其於在低氧濃度下以500勒克斯(lux)的照度照射2個月以上的情形時,亦可維持良好的耐光性。 In particular, when the illuminance of 500 lux is irradiated for 2 months or more at a low oxygen concentration, good light resistance can be maintained.
就長時間熱循環的性能的觀點而言,本發明的組成物較佳為固體成分的電壓保持率為10%~80%,較佳為60%~99%,更佳為80%~99%。 The composition of the present invention preferably has a voltage retention ratio of the solid component of 10% to 80%, preferably 60% to 99%, more preferably 80% to 99%, from the viewpoint of the performance of the long-term heat cycle. .
另外,於本發明中,藉由設定為如上所述的構成,可獲得於經過長期間後黏度的變化率小的著色組成物。例如即便於在室溫(23℃)下經過3個月以上後,亦可減小黏度的變化率。另外,本發明中,於長時間放置於各種溫度(例如-30℃~150℃)及/或高濕度(例如相對濕度80%以上)環境下的情形時,可獲得異物的產生率小的著色組成物。例如於在冷凍(-15℃以下)的環境下放置1個月以上的情形、或於在110℃85%RH的環境下放置2週以上的情形時,亦可減小異物的產生率。 Further, in the present invention, by setting the above configuration, it is possible to obtain a coloring composition having a small change rate of viscosity after a long period of time. For example, even after three months or more at room temperature (23 ° C), the rate of change in viscosity can be reduced. Further, in the present invention, when placed in an environment of various temperatures (for example, -30 ° C to 150 ° C) and/or high humidity (for example, a relative humidity of 80% or more) for a long period of time, a small color generation rate can be obtained. Composition. For example, when it is left to stand for 1 month or more in an environment of freezing (-15 ° C or lower) or when it is left in an environment of 85% RH at 110 ° C for 2 weeks or more, the rate of generation of foreign matter can be reduced.
