Wu, Luoyi et al. published their research in Tuliao Gongye in 2002 | CAS: 1552-42-7

Crystal violet lactone (cas: 1552-42-7) belongs to benzofurans derivatives.Benzofuran is one of the most significant oxygen-containing heterocycles consisting of fused benzene and furan ring, which are widely presented in various naturally occurring and synthetically active compounds. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.Computed Properties of C26H29N3O2

Preparation of low-temperature reversible discoloration microcapsule and the application in water-based coating was written by Wu, Luoyi;Hu, Zirong;Li, Yushu;Shao, Guang. And the article was included in Tuliao Gongye in 2002.Computed Properties of C26H29N3O2 This article mentions the following:

Crystal violet lactone/diphenylol propane was serviced as discoloration constituents and dodecanol as solvent, which were dispersed into 10-100 μm size in water. By coating the drops with gelatin/arabic, reversible discoloration microcapsule was prepared, which oiliness pigment was changed in powder, and so overcome the short-comings that the oiliness pigment cannot be compatible with water based paint. In the experiment, the researchers used many compounds, for example, Crystal violet lactone (cas: 1552-42-7Computed Properties of C26H29N3O2).
