Abstract: An optical assembly includes a spacer layer which is translucent or transparent; an image forming reflector which has a reflective layer being formed at least in a first region of the spacer layer; and a protective layer which is laminated over the spacer layer and the image forming reflector and the protective layer being translucent or transparent. The spacer layer is made of a polyolefin or/and a polymer containing an aryl group. The image forming reflector includes a visible image which is authenticatable. The image forming reflector has an individual information record in which a code is stored in the form of a plurality of removed linear segments. The image forming reflector has white level regions and a black level region in planar view. Each of the white level regions has the removed linear segments formed therein. The black level region is interposed between the white level regions.

Abstract: An electrode catalyst layer that suppresses degradation due to repeated starting and stopping and has excellent durability, and a membrane electrode assembly using the electrode catalyst layer. The electrode catalyst layer is an electrode catalyst layer used in a polymer fuel electrolyte fuel cell, which contains carbon particles which support catalyst, a polymer electrolyte, and a fiber material which is at least one of a carbon fiber and an organic electrolyte fiber, and the thickness of the electrode catalyst layer after performing a start-stop test from 1 V to 1.5 V for 10,000 cycles is 70% or more of the thickness of the electrode catalyst layer before the start-stop test.
