| 摘要 |
<p>This invention relates to a novel 2-(halogenomethyl-phenyl)-4-halogeno-oxazole derivative; to a radiation-sensitive composition which, as the radiation-sensitive compound, contains a 2-halogenomethyl-phenyl)-4-halogeno-oxazole derivative; and to a process for the preparation of the novel 2-(halogenomethyl-phenyl)-4-halogeno-oxazole derivatives. The novel 2-(halogeno-methyl-phenyl)4-halogeno-oxazole derivative has the general formula I I wherein Hal1 is a halogen atom, Hal2 is a chlorine or bromine atom, m is an integer from 1 to 3, n is an integer from 1 to 4, R1 is a hydrogen atom or a further CH3-mHal2m group, and R2 is a 1-valent or 2-valent, at most tetranuclear aromatic or heteroaromatic radical which may be partially hydrogenated, and at an unsaturated ring carbon atom, is linked, directly or via a chain which contains up to four exclusively unsaturated carbon atoms, to the oxazolyl part of the molecule according to the general formula I.</p> |
