ABSTRACT:
Toy figurines including toy dolls are disclosed that have skins or exterior surfaces repeatedly capable of reversibly changing color. The skin is coated with a sealant/primer base coat of flexible, hydrophobic film-forming polymeric material. Applied over the base coat is a color layer which is either continuous or of desired geometric configuration. The color layer contains acid-base indicating material, preferably microencapsulated, matrixed in a mixture of polymeric material. A top coat applied over the color layer protects the color layer against abrasion and is water permeable. The coated skin portions thus change color in response to changes in the pH of aqueous solutions applied to them.
