PURPOSE: To provide an emulsion composition having markedly improved water resistance and useful as adhesive for water-resistant corrugated board, paper, fiber, etc., prepared by adding a specified water-resisting agent to an emulsion which contains acetoacetylated polyvinyl alcohol as protective colloid. n CONSTITUTION: The emulsion composition is obtained by adding at least one water resisting agent selected from among radical former, oxidant, isocyanate compd., epoxy compd., ammonium salt, polymerizing monomer and metal salt, to an emulsion which contains acetoacetylated polyvinyl alcohol as protective colloid. The water-resisting agent is added in an amount of 1W40, pref. 10W 150wt% of the acetoacetylated polyvinyl alcohol content of the emulsion. n COPYRIGHT: (C)1983,JPO&Japio |
