A thermoplastic hot melt pressure-sensitive adhesive composition which is resistant to heat deterioration at elevated temperatures and, therefore, may be melted and maintained hot and ready for coating for extended periods of time without detracting from the properties of the adhesive. The composition is based upon a linear or radial A-B-A block copolymer and a mixture of solid and liquid tackifier resins and contains a heat stabilizing component which comprises an oil-soluble, heat-reactive phenol formaldehyde resin and a suitable antioxidant which preferably consists predominantly of a metal dithiocarbamate. |
