Abstract:
1. A multilayer film comprising: a film base formed from a polymer compound, a heat shrinkage factor of said film base after being heated at 170° C. for 10 minutes being in a range from 0.05% to 3.0%; a hard coat layer formed by applying a water-based coating liquid onto said film base and drying said applied coating liquid, said coating liquid not containing an organic solvent but containing a water soluble hardening agent and alkoxysilane aqueous solution in which an organic silicon compound represented by a general formula (I) and tetraalkoxysilane are dissolved in an acid aqueous solution having a pH in a range from 2 to 6, said hardening agent promoting dehydrating condensation of silanol generated by hydrolysis of said organic silicon compound and said tetraalkoxysilane, an amount of said acid aqueous solution being in a range from 100 parts by weight to 1500 parts by weight where a total amount of said organic silicon compound and said tetraalkoxysilane is 100 parts by weight,
