ABSTRACT:
A fluoro-carbon resinous laminate has a crack-resistant surface on a fluoro-carbon resinous layer thereof produced by coating a single surface or both surfaces of a plastic film with a single layer of a fluoro-carbon resinous dispersion, and a method of producing the laminate. To produce the fluoro-carbon resinous laminate, which is a minimum of 10 .mu.m in thickness, a single surface or both surfaces of a plastic film are coating with a single layer of concentration-adjusted fluoro-carbon resinous dispersion and then dried, followed by curing the resinous dispersion in a thermal treating furnace with heated atmospheric air or by adding organic solvent to the resinous dispersion, the enabling production of a fluoro-carbon resinous laminate having a surface appearance in which cracks cannot visually be identified.
