Silver halide recording material for making negative images having ultrahigh contrast |
| abstract |
Silver halide recording material for making negative images having ultrahigh contrast. Known silver halide recording materials for making negative images having ultrahigh contrast contain hydrazine compounds and contrast enhancing compounds (so-called boosters). The invention involves a material having a new class of such a booster, containing in its molecule at least one nitrile group and a tertiary amino group. The invention also includes a process for making black-and-white negative images having ultrahigh contrast by using the invention's materials. The invention is particularly useful in the pre-press stage for printing. |
