摘要：
The present invention relates to a hydrochromic polydiacetylene composite composition, a hydrochromic thin film using same, and a use thereof, and more specifically, to a hydrochromic polydiacetylene composite composition reacting sensitively to moisture, providing the hydrochromic thin film using same, and to applying same to biorecognition or fingerprint recognition. According to the present invention, moisture secreted from a fingerprint or pores on the skin can be detected with high sensitivity. Thus, the position of pores unique to a fingerprint of an organism can be amplified and displayed through selective color change and fluorescent change patterns exhibited when moisture is absorbed.
