樹脂を、顔料1重量部に対して、15~50重量部含み、
樹脂が、セラックを含み、顔料が、炭末色素を含み、
前記インクの乾燥後の乾燥皮膜の硬度が、鉛筆硬度で2B~4Hであり、
前記インクの乾燥皮膜の反射濃度が、0.1~0.3である
インクジェットプリンタ用インク。
本発明のインクの乾燥皮膜を有する錠剤は、錠剤の表面に、インクジェットプリンタ用インクで印刷されたインクの乾燥皮膜を有する。
本発明のインクジェットプリンタ用インクは、樹脂及び顔料を特定の含有比率で含有することを特徴とする。また、本発明のインクジェットプリンタ用インクは、錠剤の表面を印刷するために用いることができる。
前記「1.インクの乾燥皮膜を有する錠剤」を製造する方法としては、特定の表面硬度を有する錠剤の表面に、インクジェットプリンタ用インクで印刷する工程を含む。
インクジェットプリンタ用インクを調製するにあたり、以下の分散体の調製、及びセラック溶液の調製を行い、さらに、当該分散体及びセラック溶液を用いてインクジェットプリンタ用インクの調製を行った。
ヒドロキシプロピルセルロース(HPC)(粘度:2.5mPa・s(2重量%水溶液、20℃))又はヒドロキシプロピルメチルセルロース(HPMC)(粘度:4.0mPa・s(2重量%水溶液、20℃))を3重量部、水97重量部に溶解させて3重量%のHPC溶液又はHPMC溶液を調製した。
表1の「25重量%セラック溶液」の配合比率となるように、エタノール(99度)に白色セラックを加えて撹拌し、25重量%のセラック含有エタノール溶液(25重量%セラック溶液)を調製した。
前記で調製した「分散体」に対して、前記「25重量%セラック溶液」、炭酸アンモニウム、50重量%乳酸ナトリウム水溶液、エタノール、及び精製水を表1に示す配合比率で加え、よく攪拌して、インクの分散液を調製した。得られた分散液をNo.63のフィルターにて濾過した。次いで開目0.8μmのフィルターで濾過してインクジェットプリンタ用インクを調製した。
表1及び表2に示す成分及び配合比率のインクジェットプリンタ用インクを、紀州技研工業株式会社製のインクジェットプリンタ(40μノズル CCS3000)を用い、表3に示す市販の錠剤に印刷を行った。なお、使用した錠剤は、表3に示す錠剤を30cm篩上で軽く振動しながら掃除機で粉末を除去し、実施例11~14、及び比較例7については、前記粉末の除去後、表4に示す量の粉末が錠剤に付着するように、粉末(結晶セルロース:商品名セオラスPH301(旭化成(株)製))を加えて錠剤への印刷の前にポリ袋で十分に錠剤表面へまぶした。
JIS K 5600-5-4に準拠する鉛筆硬度によって測定した。なお、上記のインクの乾燥皮膜の硬度は、フィルム上に、表1及び表2に示す成分及び配合比率の各インクジェットプリンタ用インクを、紀州技研工業株式会社製のインクジェットプリンタ(40μノズル CCS3000)を用い印刷を行った際の値である。
JIS R 3255のスクラッチ法に準じて、錠剤表面が、はく離する臨界荷重値を測定した。なお、測定機として、新東科学株式会社製の連続加重式表面測定機(TYPE:22)を使用し、サファイヤ圧子R0.1mmを用い、移動速度0.1mm/secにて測定した。
錠剤の表面の粉末を除去する前と後の錠剤の重量をそれぞれ測定し、その差から算出した。
日本電色工業製の微小面色差計(VSR400)によって、錠剤の表面のインクの乾燥皮膜のドットの反射濃度を測定した。
錠剤を印刷後、3秒後に印字検査機にて行い、不良率にて評価した。
不良率が0.1%以下を〇とし、不良率が0.1%を超えるものを×とした。
印字後の錠剤同士を接触させ、設置した印字検査機にて行い、よごれ度合いの不良率にて評価した。
不良率が0.1%以下を〇とし、不良率が0.1%を超えるものを×とした。
表1及び表2に示す成分及び配合比率のインクジェットプリンタ用インクを、紀州技研工業株式会社製のインクジェットプリンタ(40μノズル CCS3000)を用い、前記の市販の錠剤(プレタールOD錠100mg(錠剤表面硬度:16g))に印刷を行った。なお、錠剤表面の粉末の含有割合を実施例8と同様の方法により測定したところ、0.05重量%以下であった。
実施例8と同様の方法により、インクの乾燥皮膜の硬度を測定した。
実施例8と同様の方法により、インクの乾燥皮膜のドットの反射濃度を測定した。
実施例8と同様の方法により、視認性及び印字ドットの剥離を測定した。
実施例8と同様の方法により、錠剤印字物と他錠剤との汚れの転着を測定した。
実施例1~7のインクジェットプリンタ用インクは、顔料である炭末色素1重量部に対して樹脂であるセラックの含有量が15~49重量部と多く、また、インク中の顔料の含有割合も少ないため、連続式のインクジェットプリンタでの印刷の適性粘度となった。そのため、安定した吐出が可能となり、素錠に対して当該インクによる印刷が良好に行えることが確認できた。また、実施例1~7のインクジェットプリンタ用インクによって印刷された錠剤は、印刷不良が少なく、良好に印刷することができることがわかった。
