Abstract

People like fashion and thermochromic dyed materials give colour when it is activated. Thermochromic colourants were activated by the stimuli temperature and the colour changes from colourless to colour and wise versa. Thermochromic materials are used in wide applications including T-Shirts, caps, thermometers, buildings, urban structures, medical thermography, food packaging, toys etc. The fastness properties of thermochromic dyes are very poor due to its particle size. In this work, the binder is used along with thermochromic dyes with different concentrations to improve the fastness properties. The other parameters like tearing strength, colour strength and thickness are also analyzed.

Keywords
