Abstract
Abstract The disclosure described novel adhesive compositions having improved cold flex characteristics and solvent resistance. The adhesive composition comprises a combination of a particular type of water-insoluble, self-cross-linking acrylic polymer and an acid polymer. These adhesives are useful in the usual applications and, in particular, in preparing laminated fabrics and flocked pile fabric.
