Abstract
Abstract A room temperature setting adhesive composition capable of giving high initial bond strength as well as cured bonds having good resistance to water and boiling contains, as main components thereof, (A) an emulsion containing an acetoacetylated polyvinyl alcohol and a vinyl acetate copolymer produced by copolymerizing an acetoacetylated, ethylenically unsaturated monomer and another ethylenically unsaturated monomer and (B) a resorcinol resin precondensate and, as a curing agent, (C) hexamethylenetetramine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
62 words
A room temperature setting adhesive composition containing, as main components thereof, (A) a polyvinyl acetate emulsion containing an acetoacetylated polyvinyl alcohol and (B) a resorcinol resin precondensate and, as a curing agent, (C) hexamethylenetetramine, characterized in that said polyvinyl acetate emulsion is an emulsion of a vinyl acetate copolymer produced by copolymerizing an acetoacetylated, ethylenically unsaturated monomer and another ethylenically unsaturated monomer.
Claim 2
Dependent Claim
62 words
A room temperature setting adhesive composition containing, as main components thereof, (A) a polyvinyl acetate emulsion containing an acetoacetylated polyvinyl alcohol and (B) a resorcinol resin precondensate and, as a curing agent, (C) hexamethylenetetramine, characterized in that said polyvinyl acetate emulsion is an emulsion of a vinyl acetate copolymer produced by copolymerizing an acetoacetylated, ethylenically unsaturated monomer and another ethylenically unsaturated monomer.
Claim 3
Dependent Claim
68 words
The room temperature setting adhesive composition of claim 1, wherein component (B) is contained in an amount of 10-50 parts by weight per 100 parts by weight of component (A) on the solid content basis and wherein component (C) is contained in an amount of 2-30 parts by weight per 100 parts by weight of the sum total of components (A) and (B) on the solid content basis.
Claim 4
Dependent Claim
37 words
The room temperature setting adhesive composition of claim 1 or 2, wherein component (A) contains said acetoacetylated polyvinyl alcohol in an amount of 0.2-20 parts by weight per 100 parts by weight of said vinyl acetate copolymer.
