Abstract
Abstract An adhesive composition comprising an aqueous dispersion of film forming resin, filler and tackifying substances. The dispersion uses wood rosin and esterified rosin as tackifying substances and also includes diethylene glycol monobutyl ether. The compositions are specially formulated to avoid use of the more volatile organic solvents which are undesirable for flammability or health reasons. The compositions are particularly suitable for use as nonflammable floor laying adhesives by methods in which porous flooring material is laid onto the wet adhesive layer or non-porous flooring material is laid onto the "semi-dry" adhesive layer.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
43 words
An adhesive composition, free of volatile organic solvent of boiling point less than about 200° C., comprising an aqueous dispersion of film-forming resin, finely divided filler, diethylene glycol monobutyl ether, and, as a tackifying substance, a mixture of wood rosin and esterified rosin.
Claim 2
Dependent Claim
43 words
An adhesive composition, free of volatile organic solvent of boiling point less than about 200° C., comprising an aqueous dispersion of film-forming resin, finely divided filler, diethylene glycol monobutyl ether, and, as a tackifying substance, a mixture of wood rosin and esterified rosin.
Claim 3
Dependent Claim
77 words
An adhesive composition, free of volatile organic solvent of boiling point less than about 200° C., comprising an aqueous dispersion of film-forming resin, finely divided filler, diethylene glycol monobutyl ether, and, as a tackifying substance, a mixture of wood rosin and esterified rosin in a weight ratio of about 1:3 to about 1:8 by weight, said mixture present in quantities to provide a weight ratio of film-forming resin to tackifying substance of about 3:1 to about 6:1.
Claim 4
Dependent Claim
77 words
An adhesive composition, free of volatile organic solvent of boiling point less than about 200° C., comprising an aqueous dispersion of film-forming resin, finely divided filler, diethylene glycol monobutyl ether, and, as a tackifying substance, a mixture of wood rosin and esterified rosin in a weight ratio of about 1:3 to about 1:8 by weight, said mixture present in quantities to provide a weight ratio of film-forming resin to tackifying substance of about 3:1 to about 6:1.
