| 摘要 |
<p>The invention provides a redox amplification colour development composition comprising an oxidising agent and a colour developing component; the composition comprising a stabiliser for the oxidising component which is also effective as an anti-fogging agent. The oxidising agent may be hydrogen peroxide and the combined stabilising agent may be uric or phosphoric acid, or a functional salt thereof. The invention also provides a photographic paper coated with such a stabiliser for redox amplification colour developer thereby to inhibit fogging.</p> |
