PURPOSE: A water-dispersible diacetylene monomer is provided to print a clear image onto various substrates and to print polydiacetylene capable of obtaining reversible color transition within a specific temperature range by a polymerization after and exposure and a polymerization. CONSTITUTION: A water-dispersible diacetylene monomer is represented by chemical formula 1. In chemical formula 1, l, m, n, x, y, and z is an integer larger than 1, l+x is an integer from 2-20, m+y is an integer from 2-4, and n+z is an integer from 2-16. An aqueous ink (110) is obtained by dispersing the water-dispersible diacetylene monomer (130) in water. A manufacturing method of a thermochromic polydiacetylene comprises a step of printing a specific image on a substrate (160) by applying the aqueous ink to an inkjet printer; and a step of polymerizing a diacetylene monomer in the aqueous ink by exposing the printed image. |
