本発明は、 水溶性銅フタロシアニン化合物錯体染料、 及びそれを 用いた記録液、 特にイ ンクジエツ ト記録法に用いられる記録液に関 する。 背景技術  The present invention relates to a water-soluble copper phthalocyanine compound complex dye, and a recording liquid using the same, particularly, a recording liquid used in an ink jet recording method. Background art
イ ンクジエツ ト記録法はィ ンク組成物の小滴を飛ばし、 紙等の記 録媒体に付着させ印刷を行う印刷方法である。 得られた画像の色再 現は、 大別してシアン、 マゼン夕、 イエロ一の 3色のイ ンク組成物 で行われている。  Ink jet recording is a printing method in which droplets of ink composition are ejected and deposited on a recording medium such as paper to perform printing. The color reproduction of the obtained image is roughly performed using three ink compositions of cyan, magenta, and yellow.
シアンイ ンク組成物としてはフタロシアニン染料が、 色度、 耐光 性、 耐熱性が高いため現在広く用いられ、 特にダイ レク ト ブルー ( Direct Blue ) 1 9 9 がイ ンクジェ ヅ ト プリ ン夕一用シアンイ ンク の染料と して広く使用されている。 優れた耐光性、 耐熱性をもつ ダイ レク トブルー 1 9 9だが、 大気中のオゾン、 窒素酸化物 (NOx ) 、 水溶液中の次亜塩素酸ナ ト リ ウム、 塩素等の酸化剤に対し耐性 がなく短時間で退色してしまう といった欠点を有していた。  As a cyan ink composition, phthalocyanine dyes are widely used at present because of their high chromaticity, light fastness and heat resistance, and in particular, Direct Blue 19 9 is a cyan ink for ink jet printing. Is widely used as a dye. It has excellent light resistance and heat resistance, but it is resistant to oxidants such as atmospheric ozone, nitrogen oxides (NOx), sodium hypochlorite in aqueous solution, and chlorine. It has the disadvantage of fading in a short time.
この欠点を克服するためイ ンクジェッ ト用イ ンク組成液としての 改良、 例えばイ ンク組成液に抗酸化剤、 ラジカル反応防止剤等を含 有させたり、 紙上に飛ばしたィ ンク表面上に皮膜形成能を有する樹 PC漏 2/04331 In order to overcome this drawback, the ink composition liquid is improved as an ink composition liquid, for example, the ink composition liquid contains an antioxidant, a radical reaction inhibitor or the like, or a film is formed on the surface of the ink jetted on paper.

また、 記録媒体である紙の改良による、 記録物の空気中のオゾン 等の酸化性ガスに対する耐性の向上も行われており、 例えば、 特閧 平 8-164664号公報、 特開平 9-254526号公報に記載されている。 さら に、染料自体の耐性を上げることも行われ、例えば、特開 2000-303009 公報には、 4ースルホフタル酸から合成したフタロシアニンスルホ ン酸が、 フタ口シァニン骨格合成後にスルホン化したフタロシア二 ンスルホン酸及びスルホンァミ ドよ り も、 酸化窒素に対し耐性があ ることが記載されている。  In addition, the improvement of the recording medium, such as paper, improves the resistance of the recorded matter to oxidizing gases such as ozone in the air. For example, JP-A-8-164664, JP-A-9-254526, and the like. It is described in the official gazette. Furthermore, it is also performed to increase the resistance of the dye itself. For example, JP-A-2000-303009 discloses that phthalocyaninesulfonic acid synthesized from 4-sulfophthalic acid is phthalocyaninated sulfonic acid sulfonated after synthesis of a lidar cyanine skeleton. It is described that N and sulfonamide are more resistant to nitric oxide.

ダイ レク トブル一 199、 ァシッ ドブル一 249 ( 4—スルホフタル酸 よ り合成したフタロシアニンスルホン酸) 及び前記実施例 1、 4、 5の染料各々について染料濃度 (質量%) が 3 %で、 1 0 %のジェ チレングリ コールを含有した水溶液を調製した。 各記録液を、 下記 表 2 に示す 1枚のイ ンクジェッ ト用専用紙 1又は 2 (縦 5 c m、 横 1 0 c m ) の小片に筆で縦 2cm横 1.5cmの大きさで均一に塗った後、 2 4時間乾燥し、 サンプル紙片を得た。  10% of the dye concentration (mass%) was 3% for each of the dyes 199, 1249 (a phthalocyanine sulfonic acid synthesized from 4-sulfophthalic acid) and the dyes of Examples 1, 4 and 5 described above. An aqueous solution was prepared containing cetylene glycol. Each recording liquid was uniformly coated in a size of 2 cm by 1.5 cm by using a brush on a small piece of paper 1 or 2 (5 cm by 10 cm) shown in Table 2 below. After drying for 24 hours, a sample sheet was obtained.
サンプル紙片をオゾン濃度が 5 0 0 p p mの容器中に 1時間入れ た後、 取り出し、 次に 2 4時間室温で放置した後の色の変化を目視 で評価した。 評価基準は以下のように行った。  The sample paper pieces were put in a container having an ozone concentration of 500 ppm for 1 hour, taken out, and then allowed to stand at room temperature for 24 hours to evaluate the color change visually. Evaluation criteria were as follows.
〇 : 青色の変化ほとんどなし  ○: Almost no change in blue
△ : わずかに緑色に変色  :: Slightly greenish
X : 青緑色に変色し色目が薄く変化  X: Change to bluish green color, light color changes slightly
結果を下記表 2に示す。 The results are shown in Table 2 below.
