摘要： The present invention provides a temperature sensitive paint for low-temperature use which shows durability at low temperatures, has a high light emission intensity, and makes it possible to perform precise temperature measurements of surface temperature fields by applying the paint to the surface of an object and measuring the light emission even in cases where the measurement distance is long in, for example, a large cryogenic wind tunnel or the like. The temperature sensitive paint for low-temperature use contains a ruthenium complex having a high light emission intensity as a temperature sensitive luminophore, a urethane type polymer as a binder, and an alcohol organic solvent as a solvent. Use of an alcohol organic solvent makes it possible to dissolve a temperature sensitive luminophore at a high solubility and to increase the light emission intensity by raising the temperature sensitive luminophore concentration in the coating film, so that more precise temperature measurements can be performed. By using the urethane type polymer having the durability at low-temperature, it is possible to obtain durability where no cracks occur at low temperatures even when the film thickness is increased. Therefore, adjustment of the light emission intensity and surface treatment such as surface polishing and the like can be performed by using this temperature sensitive paint for low-temperature use.

摘要： An oxygen-quenching luminophore constituting part of a pressure-sensitive luminophore is directly bonded by a covalent bond to an organic polymer compound having trimethylsilyl groups, so the luminophore molecules are retained in the polymer and free aggregation is inhibited when the organic solvent is evaporated. It is therefore possible to prevent light response from being reduced by the aggregation of the luminophore molecules during evaporation of the organic solvent, which is a drawback of forming films from conventional mixed-type pressure-sensitive paints. A thin-film sensor with uniform characteristics can be formed by spraying or application from a pressure-sensitive paint obtained by mixing a functional polymer with a solvent. In addition, a coating solution that has high reproducibility and is suitable for spraying or application can be obtained merely by dissolving the functional polymer as a single component in a suitable solvent. It is possible to obtain a functional polymer, a pressure-sensitive paint, and a pressure-sensitive element in which a reduction in light response due to luminophore aggregation can be prevented, and a thin sensor film having uniform characteristics can be formed, even when the organic solvent has evaporated.
