Abstract: The present invention relates to a thermosetting powder paint comprising, as essential components, (A) a copolymer of particular composition composed of a glycidyl group-containing monomer, styrene and other monomer copolymerizable therewith and, as curing agents capable of reacting with the component (A) to crosslink the component (A), (B) an aliphatic polycarboxylic acid and (C) a linear anhydride of an aliphatic polycarboxylic acid; a coating method using the above thermosetting powder paint; and a coated article obtained by using the above thermosetting powder paint. The above thermosetting powder paint, when used as a paint for automobile, has excellent storage stability and gives a coating film having excellent appearance, properties, weathering resistance and yellowing resistance; therefore, the paint can be favorably used particularly as an top coat and an intermediate coat for automobile and its parts.

Abstract: A resin composition containing graft copolymer having at least one isocyanate group and 10,000 to 20,000 number-average molecular weight or high-molecular-weight polymer having at least one isocyanate group and 10,000 to 200,000 number-average molecular weight, and low-molecular-weight polymer having or not having an isocyanate group and 500 to 8,000 number-average molecular weight. This resin composition has tackiness at ordinary temperature, and long pot life. It can be used for reactive hot melt type adhesives (which can omit hot press process), reactive hot melt type pressure-sensitive adhesives, or coating material.

Abstract: There is disclosed a resin composition containing graft copolymer having at least one isocyanate group and 10,000 to 20,000 of number-average molecular weight or high-molecular-weight polymer having at least one isocyanate group and 10,000 to 200,000 of number-average molecular weight, and low-molecular-weight polymer having or not having an isocyanate group and 500 to 8,000 of number-average molecular weight is disclosed. This resin composition has tackiness at ordinary temperature, and long pot life. It can be used to reactive hot melt type adhesives (which can omit hot press process), reactive hot melt type pressure-sensitive adhesives, or coating material.

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.
