Zusammenfassung:	PROBLEM TO BE SOLVED: To manufacture an effect pigment depending upon a visual angle with high thermal stability and high chemical stability (insolubility) and to provide a method having no disadvantage of prior art. SOLUTION: Thermoplastic cholesteric liquid crystal polymer containing at least one type or more of polymer laminate is simultaneously extrusion molded together with at least one type or more of thermoplastic support polymer, and bound with one another in the state of a thin film. This laminate can be used for manufacturing effect pigment having a color impression depending upon a visual angle by releasing the liquid crystal polymer film from the support polymer film.
