<p><P>PROBLEM TO BE SOLVED: To provide a glitter flake inhibiting the apparent intensity reduction of interference reflection light by white-reflection light, having a light-emitting function having the light interference-generated color and chromatic color jointly and capable of being developed to a merchandise field requiring an excellent esthetic property. <P>SOLUTION: This glitter flake having the light interference color-generating function is obtained by cutting a conjugate fiber constituted by an alternately laminated body part obtained by alternately laminating polymer layers having different refractive indices from each other and having 0.8≤(SP1/SP2)≤1.1 range of a ratio (SP ratio) of the solubility parameter value (SP1) of a higher refractive index side polymer to the solubility parameter value (SP2) of a lower refractive index, parallel to the long axial direction of a flat cross section, and a covering layer consisting of a fiber-forming polymer for covering the alternatively laminated body part, and the conjugate fiber has a polymer layer containing at least a chromatic component. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
