  • Patent number: 6359030
    Abstract: An aqueous-dispersing composition of synthetic resin (A) having an intrinsic viscosity “&eegr;” of from 0.3 to 2.0 measured at 35° C. in a methyl ethyl ketone solvent or a mixture of that aqueous dispersion and an aqueous dispersion of synthetic resin (B) having an intrinsic viscosity “&eegr;” of not less than 0.6 which is larger by 0.3 or more than the intrinsic viscosity “&eegr;” of the synthetic resin (A) when the intrinsic viscosity is measured at 35° C. in a methyl ethyl ketone solvent. The aqueous-dispersing composition and the mixture have improved film forming property and can give a coating film being excellent in chemical resistance, water resistance, mechanical properties and further hot water resistance.
