ABSTRACT:
The invention provides an immersion oil composition for microscope especially suitable for use in the microscopic study using a fluorescence microscope by virtue of the greatly decreased fluorescence emission under ultraviolet irradiation in comparison with conventional immersion oils. The inventive immersion oil composition comprises a liquid dienic polymer, e.g. liquid polybutadiene, as a first component and, as a second component, one or a combination of compounds including (a) chlorinated paraffins, (b) polybutene, (c) carboxylic acid esters, (d) liquid paraffins, (e) saturated aliphatic alcohols and (f) alicyclic alcohols; said composition having a refractive index in the from 1.501 to 1.519 and a Abbe's number in the range from 40 to 46.
