ABSTRACT:
The invention relates to a non-continuous matte layer that can be used with a recording material having a substrate and a radiation-sensitive layer which contains a 1,2-naphthoquinone-2-diazide and an organic, polymeric binder which is insoluble in water but soluble in aqueous alkaline solutions. This matte layer comprises 100 to 10,000 particles per square centimeter which have a mean diameter of less than 40 .mu.m and a maximum diameter of less than 80 .mu.m and a mean height of 2 to 6 .mu.m and a maximum height of 10 .mu.m, and contains a resin which has up to 0.80 mmol of acid groups and/or salt groups per gram. The matte layer is obtained by spraying on and drying an aqueous, anionically or anionically
onionically stabilized dispersion of the resin.
