A transfer printing structure capable of sensing and indicating intensity of ultraviolet rays. The transfer printing structure includes a substrate having a transfer print face and a transfer print sensitive layer laid on the transfer print face of the substrate. The transfer print sensitive layer is able to sense environmental ultraviolet rays to change its look. When a pressure is exerted onto a backside of the substrate, the transfer print sensitive layer adhesively attaches to a surface of an article or human body. When the article or human body moves outdoors, the look of the transfer print sensitive layer varies with the intensity of the ultraviolet rays to indicate the intensity of the ultraviolet rays.
