Fluorescent functional monomer, pressure-sensitive adhesive enabling timely detection of coating defects and preparation method of pressure-sensitive adhesive

The invention discloses a fluorescent functional monomer, a pressure-sensitive adhesive enabling timely detection of coating defects and a preparation method of the pressure-sensitive adhesive, and belongs to the technical field of functional coatings. The pressure-sensitive adhesive enabling timely detection of the coating defects is obtained by copolymerizing an acrylic monomer and an acrylic acid-naphthalimide functional monomer in a solvent; because the side chain of the polymer contains the naphthalimide fluorophore, after coating and ultraviolet-visible light irradiation, bright blue fluorescence exists in a normal coating area, and no fluorescence exists in a missed coating area, whether the missed coating area exists or not can be quickly observed, so that measures can be taken in time for rescue, quality accidents are reduced, and the product yield is greatly improved. 本发明公开了一种荧光功能单体、一种可及时发现涂布缺陷的压敏胶及其制备方法，属于功能涂层技术领域，本发明中的可及时发现涂布缺陷的压敏胶通过丙烯酸类单体与丙烯酸-萘二酰亚胺功能单体在溶剂中共聚而得；因高分子侧链上含有萘二酰亚胺荧光团，涂布后，经紫外-可见光照射，正常涂布
