Abstract
A photographic silver halide material is disclosed which comprises a support and on one or both sides thereof at least one silver halide emulsion layer and a protective gelatin antistress layer and which comprises in an outermost layer on the side(s) containing at least one emulsion layer a polyoxyalkylene compound as an antistatic agent, characterised in that said antistress layer comprises an ionic or nonionic polymer or copolymer latex. In addition to the preservation of antistatic properties after processing of the said material an improvement in surface glare as appreciated upon examination of medical X-ray films is obtained. Moreover the occurrence after processing of water spot defects and sticking is avoided.
