摘要： A method is described of developing a photographic silver halide element containing developable silver halide by development in the presence of a development accelerator which is a polyaddition compound having recurring units of the following general formula, the recurring units containing at least one thioether sulphur atom linked to two carbon atoms: ##STR1## wherein: Q is --O--, --S--, --S alkylene S-- or --O alkylene O-- wherein the alkylene group may be interrupted by oxygen or sulphur,Each of X.sub.1 and X.sub.2 represents oxygen or sulphur,Alk stands for alkylene which may be interrupted by oxygen or sulphur, andR is hydrogen or COR.sub.1, SO.sub.2 R.sub.1 or CONHR.sub.1 wherein R.sub.1 is an alkyl group or an aryl group andWherein at least one of R, Q, X.sub.1, Alk and X.sub.2 is or comprises a thioether sulphur atom.
