Abstract: 1424886 Spiropyrans for copying processes BADISCHE ANILIN- & SODA-FABRIK AG 20 June 1973 [21 June 1972] 29228/73 Heading C4P [Also in Division D2] Spiropyrans have the formula in which R 1 is H, alkyl, cyanoalkyl, carboxyalkyl, methoxyalkyl or cycloalkyl each of 1 - 6C, and phenyl, R 2 is alkyl of 1 - 4C, A is a benzene nucleus opt. subs. by Me, Cl, Br, or alkoxy of from 1 - 4C, and B is a benzene or naphthalene nucleus opt. substd. by Cl, Br, nitro, C 1-5 alkyl, C 1-5 , alkoxy, di-(C 1-5 )-alkylamino or C 1-5 -alkoxy-substituted carbonyl. Some ten compounds are described. They are prepared by condensing the heterocyclic bases with o-hydroxybenzaldehydes or o-hydroxynaphthaldehydes in a cyclization reaction. The spiropyrans formed may be dissolved in non-polar or weakly polar solvents, and give intense red to blue colorations when acid substances, including kaolin and similar materials. The spiropyrans may be used as dye-forming components, possibly encapsulated, for pressure-sensitive recording materials, particularly copying papers.
