DETAILED DESCRIPTION In summarizing the present invention, a first aspect of the present invention relates to a UV-A, UV-B discriminating sensor and which is characterized in the provision of a photochromic layer as the sensor portion, this photochromic layer containing a photochromic compound or photochromic composition which colors under exposure to UV of wavelength greater than or equal to 280 nm but less than or equal to 400 nm, and in the inclusion in at least a portion of the photochromic layer of a pigment which absorbs UV rays of wavelength less than 320 nm.
A second aspect of the present invention is a UV sensor provided, as the sensor portion, with a photochromic layer containing a photochromic compound or photochromic composition which colors under exposure to UV of wavelength greater than or equal to 280 nm but less than or equal to 400 nm, and which is characterized in the inclusion in at least a portion of the photochromic layer of a pigment which absorbs UV of wavelength greater than or equal to 320 nm but less than or equal to 400 nm.
A third aspect of the present invention is a UV sensor provided, as the sensor portion, with a photochromic layer containing a photochromic compound or photochromic composition which colors under exposure to UV of wavelength greater than or equal to 280 nm and less than or equal to 400 nm, and which is characterized in that at least a portion of the photochromic layer is covered with a layer containing a pigment which absorbs UV of wavelength less than 320 nm.
A fourth aspect of the present invention is a UV sensor provided, as the sensor portion, with a photochromic layer containing a photochromic compound or photochromic composition which colors under exposure to UV of wavelength greater than or equal to 280 nm but less than or equal to 400 nm, and which is characterized in that at least a portion of the photochromic layer is covered with a layer containing a pigment which absorbs UV of wavelength of greater than or equal to 320 nm but less than or equal to 400 nm
