    • An aqueous adhesive composition having pH of about 8 to 10 containing from about 25 to 75% by weight of water, the water having dispersed therein:A. from about 25 to 75% by weight of the composition, of a water-insoluble linear polymer of interpolymerized monoethylenically unsaturated monomers in amounts by weight based on the linear polymer:(1) from about 50 to 99% of an acrylic ester monomer of the formula ##STR1## or a mixture thereof, where R is H or methyl and R.sup.2 is lower alkyl of 1 to 4 carbon atoms,(2) from about 0.1 to 10% of acrylic acid or methacrylic acid,(3) from about 0.1 to about 10% of a nitrogen containing monomer selected from the group consisting essentially of vinyl amines and salts thereof, vinyl ureido monomers, vinyl compounds having heterocyclic nitrogen containing groups, and mixtures thereof, andB. 0.001 to 2% of a silane containing both alkoxy and epoxy functionalities.

    • An adhesive composition which comprises for each 100 parts, by weight, of an aqueous dispersion having a pH of from about 3 to 10 of the following ingredients dispersed in 25 to 75 parts of water.A. from 25 to 70 parts by weight of a water insoluble polymer containing the following interpolymerized monoethylenically unsaturated monomers.A. at least 50% by weight, based on the polymer, of acrylate monomers;B. from about 0.1 to 10% by weight based on the polymer, of N-methylolacrylamide, andC. from about 0.1 to 25% by weight, based upon the polymer, of a monoethylenically unsaturated monomer containing carboxylic acid groupsD. from about 2 to 40% based upon the polymer of an acrylonitrileE. from 0 to 40% by weight based on the polymers of an addition polymerizable vinyl monomer other than those defined aboveF. from 0 to 1% by weight based on the polymer of a cross-linking agentB. a small but effective amount to thicken the acrylate composition up to 3 parts by weight of the composition of an alkali metal or ammonium salt of a polyacrylic acidC. from a small but effective amount to impart freeze-thaw stability up to 3 parts of a surface active agentD. from a small but effective amount to depress the freezing point of the dispersion up to 3 parts of a freezing point depressorE. from a small but effective amount to render the dried adhesive tacky up to 10 parts of a tackifying agent. Compositions within the scope of the present invention are useful as contact adhesives. These adhesives have the same utility as known contact cements that effect strong instant bonds on contact with a variety of substrates including plywood, hardboard, particleboard, wood, leather, floor coverings, Styrofoam, metal sheeting and plastic laminates such as Formica. The cured adhesive films formed are resistant to oil, gasoline, water, heat and discoloration or aging.
