    摘要: A spray process for the deposition of carboxyl-containing adhesive latices as discrete droplets wherein the droplets are maintained as raised, spaced deposits on the substrate for lamination is provided. The adhesive latex is sprayed at a low viscosity but prior to contact with the substrate the viscosity of the latex droplets is increased so that upon striking the substrate the droplets remain as raised, spaced deposits rather than coalescing to form a a continuous adhesive layer or being absorbed by the substrate. Laminates obtained with the present spray process have increased resistance to delamination, good flexibility and hand.
