Use of a multiple range indicator for determining the dose of UV-radiation in at least two wavelength-ranges and method for the determination of a dose of UV radiation

摘要

A multirange indicator comprises first indicator system, which encompasses first indicator dye and photolatent Lewis acid or photolatent Lewis base, and which, on exposure of the photolatent Lewis acid or base to electromagnetic radiation, is capable of liberating Lewis acid or base and of changing light absorption of first indicator dye; and second indicator system, which encompasses second indicator dye, and which is capable of changing light absorption of second indicator dye which is a triphenylmethane dye. Multirange indicator comprises first indicator system, which encompasses first indicator dye and photolatent Lewis acid or photolatent Lewis base, and which, on exposure of the photolatent Lewis acid or, respectively, photolatent Lewis base to electromagnetic radiation with wavelengths from first radiation wavelength range, is capable of liberating Lewis acid or base and of changing light absorption of the first indicator dye during a first reaction of the first indicator dye with the liberated Lewis acid or base; and second indicator system, which encompasses second indicator dye, and which is capable of changing light absorption of the second indicator dye in second reaction on exposure to electromagnetic radiation with wavelengths from second radiation wavelength range, where the second indicator dye is triphenylmethane dye. A central carbon atom of the methane group has bonding to a structural unit comprising halogens, pseudohalogens, chalcogens, sulfates, and optionally substituted tosylates, and >= 1 of the C6 rings of the phenyl groups has, in ortho- or para-position with respect to the bond to the central methyl carbon atom, an electron-withdrawing substituent with +M effect, and/or has, in meta-position with respect to the bond to the central methyl carbon atom, an electron-donating substituent with +M effect. Independent claims are included for: (1) a method of producing a dose measurement coating for the measurement of UV radiation and/or of electron-beam radiation comprising employing the multirange indicator; (2) a dose-measurement coating material for the measurement of UV radiation and/or electron-beam radiation; (3) a method for producing a flat dose-measurement element for the measurement of UV radiation and/or electron-beam radiation; (4) a flat dose-measurement element for the measurement of UV radiation and/or electron-beam radiation; and (5) a method for determination of the dose of electromagnetic radiation incident on a test specimen comprising providing portion of the surface of the test specimen with the multirange indicator, exposing the test specimen to electromagnetic radiation, recording change in the light absorption of first and second indicator dyes, and determining and using calibration values, the dose of the incident electromagnetic radiation.
