PROBLEM TO BE SOLVED: To provide an optical molded laminate capable of coping with the lot-size reduction and diversification by applying a print technology to a raw film in the case of the coloring with the conventional dying or resin coloring, with respect to the optical molded laminate used as sun glass lens, sport goggle lens, corrective lens or the like. SOLUTION: The optical molded laminate having polarization performance which is made to correspond to various colors and designs can be obtained as follow: color printing is performed by using a transparent ink comprising a transparent colorant on one surface of a polarizing sheet obtained by sticking a cellulose triacetate film to both surfaces of a polarizing film via an adhesive layer, an adhesive side surface of a plastic film used for melt-adhering the polarizing sheet and lens molding resin, with the polarizing sheet, or the cellulose triacetate film surface of the polarizing sheet after adhering and laminating the polarizing sheet and the plastic sheet; a laminate sheet obtained by using the raw material colored by the respective means is thermally bent into an object shape such that the polarizing sheet side becomes an outer surface and the plastic film side becomes an inner surface; the thermally bent sheet is inserted to a forming mold; and lens molding resin material which is melt-adhered to the plastic film is injection-molded on the plastic film side.
