Abstract
A coat layer and a substrate layer are combined to prepare a transparent laminate film; the coat layer contains particles having a particle size distribution with a plurality of peaks in a particle size region of not less than 6 μm, and of particle sizes corresponding to the plurality of peaks, the smallest particle size is larger than an average thickness of a flat portion of the coat layer. The transparent laminate film provides a comfortable writing experience and an excellent anti-glareness. The particles in the coat layer may contain small particles having a particle size of not less than 6 μm and less than 12.5 μm and large particles having a particle size of more than 12.5 μm and not more than 20 μm, and the average particle size of the small particles may be larger than the average thickness of the flat portion of the coat layer. The coat layer may further comprise a polyfunctional (meth)acrylate, and a urethane (meth)acrylate and/or a thermoplastic elastomer.
