Abstract (en)
[origin: EP0699952A1] A photographic material is provided comprising a support, a subbing layer, at least one hydrophilic gelatinous silver halide emulsion layer, optionally one or more other hydrophilic gelatinous layer(s) and a core-shell latex polymer, comprising a core (co)polymer and a shell (co)polymer characterised in that (i) said core-shell latex is present in at least one of said hydrophilic gelatinous layers, (ii) said shell (co)polymer comprises moieties A derived from at least one ethylenically unsaturated monomer having a reactive methylene group and (iii) said moieties A present in said shell (co)polymer make up between 1 and 30 % by weight of all moieties present in both said core and said shell (co)polymer and (iv) said moieties A present in said shell (co)polymer make up between 2 and 50 % of all moieties present in said shell (co)polymer. The material shows both high dimensional stability and high scratch resistance.
