    Abstract: Dye-labeled tackifiers increase dye solubility/compatibility and provide an improved means of introducing dyes into products such as inks, adhesives and coatings. When the dyes are radiation absorbing dyes, the dye-labeled tackifiers can serve as thermal transducers, and can be used in applications where it is required to cause a thermoplastic material to melt or to soften, for example a hot-melt composition.

    Abstract: The subject invention provides reactive hot melt adhesive compositions comprising polyurethane prepolymers which have an isocyanate index greater than one and which are prepared from a low hydroxyl number composition comprising high molecular weight polyester diols which have a relatively low melting point. These reactive hot melt adhesive compositions have a faster setting speed than conventional reactive hot melt adhesive compositions. The subject invention also provides a method for bonding articles together which uses such reactive hot melt adhesive compositions and articles which comprise the reactive hot melt adhesive compositions.
