PURPOSE:To increase the adhesive power between a thin transparent film and antireflection layer by supplying a polymer soln. prepd. by dissolving specific fluorine-contained polyacrylate onto a thin cellulose deriv. film and forming the antireflection layer by a spin film forming method. CONSTITUTION:The polymer soln. prepd. by dissolving the fluorine-contained (meth)acrylate which contains the monomer selected from formula I and has =50wt.% fluorine content in the polymer into the solvent which can dissolve said fluorine-contained (meth)acrylate and does not dissolve or swell the substrate-shaped cellulose deriv. and has the b.p. in a 40-220 deg.C range is supplied into the dried thin cellulose derive. film and the antireflection layer consisting of the fluorine polymer is formed by the spin film forming method. In formula, R1 denotes H or methyl group; R2 denotes a fluoroalkyl group which may con tain an ether-oxygen atom in-between. The inter-layer adhesive power between the cellulose derive. layer and the fluorine-contained poly(meth)acrylate polymer layer is thereby increased and the two layers are pulled and stripped without separating the film.
