Abstract
Abstract An aqueous dispersion of partially neutralized ethylene/α,β-ethylenically unsaturated carboxylic acid copolymer having a specific composition distribution of the acidic units is found to have an excellent film-forming property and suitable for coating of various substrates. Articles coated with said aqueous dispersion are improved in various properties such as heat-sealability, oil resistance, water resistance, adhesiveness and so on.
