Abstract: 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.
