Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new transparent laminate film excellent in transparency and thermal dimensional stability at a high temperature (for example, 200°C or higher).SOLUTION: The laminate film for a transparent substrate includes a cured layer in both of top and back sides of a base film. The laminate film is firstly characterized in that: the cured layer is formed by using a curable composition comprising a photopolymerizable compound (A) having a molecular weight ranging from 215 to 4000, a photopolymerization initiator (B) and fine particles (C); and the layer includes at least the fine particles (C) by 50 mass% or more with respect to the whole composition. The laminate film is secondly characterized in that: when the laminate film is heated at 200°C for 10 minutes, a thermal shrinkage of the laminate film in at least one direction is 70% or less of a thermal shrinkage when the base film is heated under the same conditions; and the total ray transmittance of the laminate film is 80% or more.
