A process for preparing a molded product of thermochromic polyvinyl chloride characterized by incorporating a thermochromic particulate material into a vinyl chloride plastisol comprising a vinyl chloride resin, plasticizer, stabilizer, lubricant and filler, and molding the resulting mixture. The thermochromic particulate material is prepared from particles of a non-thermoplastic resin having encapusated therein the three components of electron-donating chromogenic substance, electron-accepting substance and solvent by coating the particles with a hydrophilic high-molecular-weight compound.

Process for preparing a molded product comprising thermochromic polyvinyl chloride, which comprises incorporating a thermochromic particulate material into a vinyl chloride plastisol comprising a vinyl chloride resin, plasticizer, stabilizer and lubricant and molding and heating the resulting mixture to form the product, the thermochromic particulate material being prepared from particles of a non-thermoplastic resin having encapsulated therein the three components of electron donating chromogenic substance, electron accepting substance and solvent, said three components comprising a thermally color changeable reversible color system, by coating the particles with a hydrophilic high-molecular weight compound which is resistant to penetration of the plasticizer, stabilizer and lubricant therethrough into the particles and thereby providing the particles as corresponding double capsules having a hydrophilic high-molecular weight compound outer encapsulating and inward penetration protective layer and a non-thermoplastic resin inner encapsulating and outward penetration protective layer.
