ABSTRACT:
There is disclosed an actinic-radiation-curing, hot-melt pressure-sensitive adhesive composition, which comprises a mixture in a limited mixing ratio of an acrylic high-molecular-weight polymer that is made up of main chain having a molecular weight of 8,000 to 100,000 and a glass transition temperature of -75.degree. to -20.degree. C., and branched chain, in which the main chains and/or branched chains have or at least one ethylenically unsaturated group; and a low-molecular-weight polymer having a molecular weight of 500 to 8,000 and a glass transition temperature of lower than 100.degree. C., which polymer has or does not have an ethylenically unsaturated group in the molecule.
