Abstract
A process for producing a multi-layer film having a plurality of synthetic resin layers laminated on a releasable flat substrate by casting, which comprises firstly forming on the substrate a synthetic resin layer having adhesive or sticking properties, and then casting and curing on the synthetic resin layer having adhesive or sticking properties at least one kind of reaction-curable resin raw material mixture substantially free from a solvent to form at least one cured synthetic resin layer, so that the uppermost layer is composed of a cured synthetic resin superior in surface properties to its adjacent layer. Further, surface defects transferred from the substrate to the adhesive layer are substantially eliminated by a subsequent lamination step.
