Abstract
PURPOSE: To obtain an amino adhesive having improved storage stability and temporary adhesion, by using an amino resin, a partially saponified polyvinyl alcohol, and aluminum sulfate.
CONSTITUTION: An amino resin adhesive for plywood is obtained by incorporating (A) an amino resin, e.g. urea resin, etc. with (B) a partially saponified polyvinyl alcohol, preferably having a saponification degree of 70W90 mol % and an avierage polymerization degree of 300W3,000 and (C) aluminum sulfate. Preferably, the amount of ingredient (B) is 0.5W5% based on the weight of ingredient (A), and that of ingredient (C) is 0.01W2% calculated as the anhydride on the basis of the weight of ingredient (A)
