비교예 1-2: 표지 수율 측정
상기 비교예 1a에서 FPI-774을 증류수에 용해하는 대신에 DMF에 용해하는 것을 제외하고는 비교예 1a와 동일하게 실험을 진행하였으며(비교예 1), 상기 비교예 2a에서 FPG-456을 증류수와 DMF 1:1 혼합용매에 용해하는 대신에 DMF에 용해하는 것을 제외하고는 비교예 2a와 동일하게 실험을 진행하였다(비교예 2).
비교예 4a 및 5a: 표지 성능 및 안정성 등 비교
위 비교예 3a에서 증류수에 용해시킨 6개 염료(②, ⑤, ⑥, ⑦, ⑧, ⑨)에 대해서 증류수 대신에 증류수와 DMF의 1:1 혼합용매에 용해하는 점을 제외하고는 비교예 3a와 동일하게 실험을 진행하였으며(비교예 4a), 또한 위 실시예 3'에서 증류수와 DMF의 1:1 혼합용매에 용해시킨 3개의 염료(①, ③, ④) 증류수에 용해하는 점을 제외하고는 실시예 3'과 동일하게 실험을 진행하였다(비교예 5a).
그리고 나서 육안으로 관찰한 결과, 비교예 4a와 5a의 염색강도가 비교예 3에 비해서는 향상되었으나, 비교예 3a와 실시예 3' 각각에 비해서는 표지 성능이 떨어짐을 확인하였다.
뿐만 아니라, 비교예 3a와 실시예 3'의 경우와는 달리 비교예 4a와 5a의 경우에는 반응 후 이탈기가 부분적으로 분리되어 소량이나마 부산물이 발생하거나 또는 염료 석출의 문제가 발생할 수 있음을 확인하였다.
