Abstract (en)

[origin: WO8908486A1] A toy (10, 30) painted with paint containing thermochromic material which changes color as the temperature of the toy (10, 30) varies. Selected portions of the toy (10, 30) may be painted with the thermochromic material to provide a variety of patterns (14), designs (16, 60), numbers (20, 58), letters (18, 29, 31, 56) or other indicia which change color in response to temperature variations. In addition, different portions of the toy (10, 30) may be painted with different paints containing different colored thermochromic materials.
