摘要：
Compounds of the formula I are suitable as thermal development and diffusion promoting agents for the heat development process. With the aid of said compounds higher color transfer densities can be achieved and/or the development time can be shortened. ##STR1## wherein X.sub.1 denotes --SO.sub.2 -- or--CO--;R.sup.1 to R.sup.4 denote alkyl, cycloalkyl, aralkyl or aryl;R.sup.5 and R.sup.6 denote acyl or a group as defined for R.sup.1 to R.sup.4 ; and R.sup.1 together with R.sup.5, R.sup.2 together with R.sup.6, R.sup.3 together with R.sup.4 and/or R.sup.1 together with R.sup.2 may in each case form a heterocyclic ring containing at least one nitrogen atom.
