<P>PROBLEM TO BE SOLVED: To provide a structural color development which can allow an angle range of observable structural colors to be widened and various structural colors to be observed according to an observation angle. <P>SOLUTION: The structural color development 1 of a film-like shape has a front surface layer 10 disposed on the front surface 1a side thereof and a back surface layer 20 disposed on the back surface 1b side thereof. Each of the front surface layer 10 and the back surface layer 20 contains a block copolymer and has a micro phase-separated structure including lamellar micro domains, each of which has a wave-like shape having amplitudes in the thickness direction D1 of the structural color development 1. The maximum value of prescribed distances d1 in the micro domains 12 of the front surface layer 10 is made larger than the wavelength of a visible light range and the prescribed distances d2 in the micro domains 22 of the back surface layer 20 are made equal to or smaller than the wavelength of the visible light range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
