    Abstract: The patch for tooth whitening of the present invention includes a tooth-adhering layer (1) containing erodible polymer complexes formed by hydrogen bonding of a polymer with a carboxyl group (—COOH) and a polymer with a carbonyl group (—C═O) or ether group (—O—) and a tooth whitening agent; and an erosion rate-controlling layer (2) containing a mixture of a hydrophilic polymer and a film-forming polymer, wherein the patch is in a film form and is characterized by being eroded until extinguished after releasing the tooth whitening agent. When applied to the teeth, the patch releases a peroxide tooth-whitening agent while being hydrated by water in the mouth during a prescribed period, and thereafter, eroded until extinguished, thereby not requiring an additional detaching work from the teeth. Therefore, the patch is convenient in use and greatly reduces an obstruction sensation. Moreover, the patch has an excellent whitening effect.

    Abstract translation: 本发明的牙齿美白用贴剂包括：通过聚合物与羧基（-COOH）的氢键和具有羰基（-CO）或醚的聚合物（-CO）形成的含有可侵蚀聚合物络合物的牙齿粘附层（1） 基团（-O-）和牙齿增白剂; 以及包含亲水性聚合物和成膜聚合物的混合物的侵蚀速率控制层（2），其中所述贴剂是膜形式，其特征在于在释放牙齿增白剂后被侵蚀直到熄灭。 当施用于牙齿时，补片在规定的时间段内释放过氧化物牙齿增白剂，同时在口中水分水合，然后腐蚀直到熄灭，从而不需要从牙齿进一步的分离工作。 因此，贴片使用方便，大大降低了障碍感。 此外，贴剂具有优异的美白效果。
