Thermochromic inks are pigments that change color to colorless at certain temperature. There are many different types of thermochromic pigments including textile inks for textile screen printing.
Usually you mix normal textile pigments with thermochromic inks so that it looks like the ink is changing from one color to the other. For example, if you mix yellow normal pigment with blue thermochromic ink, you will get green ink that changes from green (under reaction temperature) to yellow (over reaction temperature).

The good thing about this company is that they have smaller quantity (100ml bottles) with affordable price (please ask directly to Zenit about the price list), but they have only 27 degrees reaction temperature inks. The colors come as concentrated pigments and you need to mix with textile binder to print.
B&G color change
http://www.colourchange.com/
They have wide variety of inks with reaction temperature and colors. The bad thing is that their minimum order is quite big quantity (4kg for BPA free ink). Please ask directly to B&G color change for the price list. The ink comes as 1:1 mix with binder.
SFXC
The B&G color/ LCR Hallcrest is now selling small quantity via SFXC (https://www.sfxc.co.uk/collections/thermochromatic-thermochromic-pigments-ink-paint).
LCR Hallcrest has also test kit from their website, but it is only 50g pack, and it is a bit too small for making projects. SFXC sells up to 5kg package (this includes 50/50 mix binder weight) with various colors and reaction temperature, and the price seems reasonable. (well, thermochromic ink is not a cheap ink. but if you do bulk order with industrial company, it is almost the same price) They even have small quantity liquid crystal!

Can these inks be used on leather? coated or a specific type of leather?
