发明名称 Thermochromic urinal mat
摘要 A waterproof urinal mat which contains humorous or informational messages printed or coated over with thermochromic inks. The mat is formed to fit in a urinal, such that included text and artwork printed onto the mat with temperature sensitive, thermochromic inks display multiple images at an ambient temperature and upon being contacted with urine or flush water. In alternative arrangements, thermochromic inks of selected activation temperatures are variously printed onto the substrate in relation to an opaque image before coating the substrate with a waterproof covering or laminate. Two or more images are thereby visible upon contacting the mat with urine and flush water. Apertures and protrusions at the mat prevent splashing and direct liquid flow relative to the images.
