Abstract

PURPOSE:To obtain the titled material which contains a specific phenothiazine derivative as color-reaction material and is excellent in the speed of color development, photo-resisting property, etc. and useful for pressure-sensitive transfer paper and the like. CONSTITUTION:The color-developing recording material containing as color-reaction material a compound expressed by formula I (wherein R<1>, R<2>, R<3> and R<4> are a lower alkyl; X is S, O, Y is a phenyl group having any one of amino, pyrrolidino and piperidino). The compound expressed by formula I is a colorless compound in itself, but it develops color very rapidly and shows excellent light resistance when brought into close contact with an electron-accepting substance selected from active clay materials such as acid terra alba, solid acids such as succinic acid and acidic organic polymers such as bisphenol A. For example, compounds expressed by formulas II and III show excellent speed of color development and light resistance in comparison with known benzoyl leuco-methylene blue expressed by formula IV.
