[0005] However, the color of the general printing paste is determined by the pigments it fills. Once the printing paste is printed and dyed into a pattern, the color of the pattern is determined, and the color of the pattern will not change again, although the pattern on the clothes improves the beauty. , but the inability to change the color also makes the color of the pattern more monotonous, and it is difficult to meet the increasing aesthetic needs of people. Therefore, there is an urgent need for a printing paste that can change colors to fill the gaps in the market

Abstract
The invention relates to the technical field of mucilage, and particularly relates to environment-friendly leather-like velvet photochromic printing paste and a preparation method thereof. The environment-friendly leather-like velvet photochromic printing paste comprises 50-75 parts of water-based acrylic emulsion, 5-15 parts of microsphere foaming agent, 10-20 parts of organic matter containing naphthopyran, 0.15-0.375 parts of dispersing agent and 0.85-2.125 parts of wetting agent. The invention further discloses a preparation method of the environment-friendly leather-like velvet photochromic printing paste. The preparation method comprises the following steps: step 1), adding the water-based acrylic emulsion into a container, adding the dispersing agent and the wetting agent while stirring, and stirring for 10-20min after adding to form a mixed solution; and step 2), adding the microsphere foaming agent and the organic matter containing naphthopyran into the mixed solution, stirring for 30-50min, and filtering to obtain the environment-friendly leather-like velvet photochromic printing paste. The printing paste disclosed by the invention has a photochromic effect.
