1. LCR Hallcrest http://www.liquid-crystal.com/
2. B&H colour change http://www.colourchange.com/
3. Thermochromic Inks http://www.thermochromicinks.com/reversible-thermochromic-ink.html
The 2nd is the right to contact.

1. Thermochromic Ink perchase
Company: B&H
Contact person: Peter
Contact No.: +44 (0) 1244 817115
Procedure:
1. Initially Peter was saying that they had liquid crystal ink (encapsulated slurry ) that could be applied on textile and asked us for detail of customization. I was glad to hear this news.
2. below is the specifications we send to Peter.
1) Original colour at RTP(about 24degree celcius) is colourless
2) Spectrum of colour ranges from 25degree celcius to 30degree celcius 3) Activation temperatures: 25 Red 26 Green 27 Blue 28 Yellow 4) Can be applied on Textile (Important) 5) Reversible
3. However one week later, we were informed that, as their technician suggested, liquid crystal slurry could not be applied on textile anyhow. The properties of the ink are unstable under exposure to UV light. This information is same as what we ever heard about liquid crystal inks. Therefore, as Jayanth also suggested, we should just start with normal type of thermochromic ink.
4. The size of the ink for sale is min 1kg. The sample size is 250g. After negotiating, peter agree to send us one sample of the ink for free while we have to pay for the other two samples.
The finalized order is as follows:
COLOUR Activation Temperature Size Price
Red -> Transparent 15 250g free
Blue -> Transparent 31 250g 60 pounds
Green -> Transparent 49 250g 60 pounds
