Sheet recording material containing dye-forming components. |
摘要 |
<p>A sheet recording material contains a layer of an electron-acceptor, such as a phenol derivative, salicylic acid derivative, metal salt of aromatic carboxylic acid, acid clay or novalak resin and a layer containing as a colorless former a dimer composed of 3-(4-substituted aminaryl)-3-(substituted indol-3-yl)-phthalide moieties connected via an alkylene or alkylene group having from 1 to 20 carbon atoms and containing therein an oxygen atom or a nitrogen atom. 4 general formulae are given and 34 specific compounds, with various substituents on rings or N atoms. Heat-sensitive material includes also a heat-fusible compound; sheets sensitive to light, pressure and electric heating are also described. The composition(s) with a binder are coated on a support, e.g. of paper. After image-forming, a blue image which is fast to sunlight is obtained.</p> |
