The invention relates to a film-formed thermochromic composition intended for use in covering the surface of exterior elements of buildings and to a process for their preparation. According to the invention, the composition consists of 1 ... 20% microencapsulated thermochromic materials, 1 ... 10% pigment, 10 ... 50% filler, 5 ... 30% emulsified resin, 0.5 ... 15% rheological additive, 0.1 ... 5% antifoam additive and respectively dispersing agent, 0.1 ... 2% antimould additive, 0.1 ... 10% coalescing agent, 10 ... 30% demineralized water, with a pH value of 6.5 ... 9.5, the percentage being expressed by mass. The process, according to the invention, consists in preparing the mixture of dispersing and coalescing agents with antimould and anti-foaming additives, emulsified resin and water, followed by kneading the pigment and filler, stabilizing the dispersion, adjusting the viscosity, after which the thermochromic materials encapsulated are dispersed in the film-like composition thus formed.
