Claims14
A method of imparting colour to a textile, comprising:
- treating the textile with an activatable diacetylene compound;
- activating the activatable diacetylene compound using heat that causes crystal form modification, wherein said compound does not change colour upon the activation;
- and
- irradiating the textile with light energy to change the colour of the activated diacetylene compound,
- wherein the activatable diacetylene compound is an amide derivative of a diacetylene.
