摘要：
AbstractA series of 5-substituted 1H-tetrazoles were studied as potential developers for thermochromic compositions based on crystal violet lactone. The relationship between the pKa values of the developers and their effectiveness in inducing color changes in the composition was analyzed. Certain 5-substituted tetrazoles demonstrated high color contrast, making them a promising alternative to bisphenol A, which is widely used as a developer.
