    摘要: Imaging films and film-forming compositions are provided which include a reducible tellurium compound, a reductant precursor, a source of labile hydrogen incorporated in a matrix. The reductant precursors are of the formulae ##STR1## where Y.sub.1 is alkoxy, Y.sub.2 is chloro or alkoxy and Y.sub.3 is hydrogen, chloro or alkoxy.Methods are provided for synthesizing the reductant precursors.

    摘要: Manufacture of benzoquinones by uninterruptedly bringing together and mixing an aniline with chromic/sulphuric acid at a temperature (y) of 0-100*C and operating with a maximum residence time in the reaction zone of x minutes, the relationship between x and y being y2 12500/x therefore + 0.8 PROVIDED THAT IN NO CASE DOES X EXCEED 360.
