Claims
- 1. A composite film comprising a continuous phase of at least one resin and a discontinuous phase of microdomains, which are 0.03 to 10 microns in size and are aggregates of particles of at least one insoluble resin prepared by applying to a substrate a resinous composition consisting essentially of
- (a) a liquid medium
- (b) at least one resin which is soluble in said liquid medium and capable of forming a continuous phase in the film,
- (c) particles of at least one resin which is insoluble in the combination of said (a) and said (b) and capable of forming a discontinuous microdomain phase in the film, and
- (d) a microdomain forming agent which is an organic compound fulfilling the requirements
- R.gtoreq.160
- at least one In.gtoreq.70
- .SIGMA.In/R.gtoreq.0.5
- wherein R represents a quantity of organic characters, In is a quantity of inorganic characters of inorganic group No. n, and n is an integer of 1 and more and corresponds to the number of inorganic groups in the molecule, and drying, baking or both baking and drying.
