Boosters for high contrast silver halide imaging elements |
| 摘要 |
<p>Boosters for high contrast negative-acting silver halide emulsions comprising hydrazine derivatives. The boosters comprise a polyoxyethylene chain terminated at one or both ends by a group comprising a benzyl alcohol or a diaylcarbinol functionality. Compounds having at least 8 carbon atoms in the polyoxyethylene chain are novel.</p> |
