PROBLEM TO BE SOLVED: To provide a production method for a multi-color band-like simultaneous cast film with no pin hole and color unevenness, clear border line, excellent appearance and large strengths of border lines of a multi-color band, capable of being efficiently produced, and to prepare an adhesive sheet using the multi-color band-like simultaneous cast film obtained by the production method. SOLUTION: The multi-color band-like cast film is formed by simultaneously casting two or more organo-sol coating liquids each having TI value in a range of 1.5-6.0 and different colors such that each of them becomes two or more band-like shapes on a step film and the adjacent bands become in the closely contacted state. Thereafter, the multi-color band-like cast film is heated/melted to form a gel and the multi-color band-like simultaneous cast film is produced. COPYRIGHT: (C)2006,JPO&NCIPI
