The present invention provides an aromatic polycarbonate resin having high fluidity and thin-wall moldability as well as excellent transparency, impact strength, and bending resistance; a polycarbonate resin composition containing it; and a method for producing a molded article by injection molding thereof. This object is achieved by an aromatic polycarbonate resin containing a carbonate structural unit (A) represented by Formula (1) and a carbonate structural unit (B) represented by Formula (2), which aromatic polycarbonate resin satisfies the following: (i) the flow value (Q value) as measured using a Koka flow tester according to Appendix C of JIS (1999) K7210 at 240° C. at 160 kgf/cm.sup.2 is not less than 6 (unit: 10.sup.−2 cm.sup.3/sec.); and (ii) the glass transition temperature (Tg) is 90 to 145° C.

The present application relates to a gel polymer electrolyte, a method for producing a gel polymer electrolyte, and an electrochromic device comprising the same. As the gel polymer electrolyte comprises a block copolymer, the present application can simultaneously satisfy high ionic conductivity, low turbidity and adhesiveness.

A resin particle includes a fluorescent colorant and a color pigment. A hue angle of the resin particle and a hue angle of the fluorescent colorant are different from each other. When a fluorescence peak wavelength in a spectral reflectance of the fluorescent colorant is represented by A (nm), an integrated value of a spectral reflectance (%) of the color pigment in a wavelength range of from A−30 (nm) to A+30 (nm) is 2,500 or more.
