A layer structure with temperature-sensitive color change

Abstract

The invention relates to a layered structure with temperature-sensitive discoloration. The layered structure comprises a surface layer and a bottom layer, wherein a first pattern layer is provided on the upper surface of the surface layer, and a second pattern layer is provided on the upper surface of the bottom layer, The second pattern layer is arranged between the surface layer and the bottom layer, and both the first pattern layer and the second pattern layer are a temperature-sensitive layer formed by a temperature-sensitive color-changing ink. The invention provides a layer structure with temperature-sensitive discoloration. Two pictures with different colors and contents are attached to the urine pocket of the men's toilet by using the principle of temperature-sensitive materials, and when the urine is sprinkled on this picture , use the temperature of about 35 degrees that comes with urine to change the color and pattern of the picture attached to the surface, thereby revealing the pattern and color of the picture on the bottom layer, and curious men will focus on urinating on the surface. on the picture above the urinal to reduce urine dripping outside the urinal.

Description

technical field [0001] The present invention relates to a layer structure, more specifically, to a urinal that utilizes the principle of temperature-sensitive materials and is pasted on the urinal of the men's restroom, and the pattern and color of the urinal can be changed by the temperature of about 35 degrees that comes with the urinal. layer structure. Background technique [0002] At present, the urinals in the prior art or the urine pockets in the men's bathroom are only made of ceramics, and the color is single, all white. This design has brought many "old and difficult" problems to the men's bathroom, that is, the urine is splashed on the ground indiscriminately. Every men's restroom has to post the slogan "one small step forward, one giant leap forward for civilization", but up to now, none of the toilet diapers on the market can solve the fundamental problems mentioned above. Contents of the invention [0003] The technical problem to be solved by the present in...
