Cold Activated Beer Can Question ?

This past Spring, The Coors Company introduced there new Cold Activated Cans. For any that do not know, The cans contain a picture of the Rockie Mountains, When the can is above 40 degrees F, The printing is White, When the can and it's contents are chilled to below 40 F Dg's, The white printing turns into a Blue, and then again to white as the beer warms.

What type of Thermo~reactive chemical do they use in there printing paints that would have this reaction, just currious ? Thanks
