ABSTRACT:
The present invention discloses solventless composition suitable for application as a hot melt to a substrate, said composition comprising a mixture or alloy of resins, selected such that the averaged glass transition temperature (Tg) of the combined unreacted resins is greater than -30.degree. and less than +60.degree. C. The melt viscosity of the unreacted resins are selected so that the combined resin mix has a melt viscosity of from about 0.05 to 25 Poise when measured at 180.degree. C. and at a shear rate of 10,000 Hz.
