Abstract

Partly hydrolysed graft polymers (I) of vinyl acetate (II) on polyethylene oxide (III) of average mol. wt. 1000-4000 are used to increase the dot quality of lith emulsions. (I) pref. contains 10-60% (II) before hydrolysis. It can be used in concns. of 0.1-5 g/1 developer and/or 0.03-1.0 g/kg emulsion. (I) cause an increase in the speed without detriment to the dot quality.
