    摘要： Provided is a double sided pressure-sensitive adhesive sheet that is produced using a plant-derived raw material, is global environmentally-friendly, can have reduced adherend selectivity, and exhibits stable adherability to adherends. The double sided pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer made from a polyester-based pressure-sensitive adhesive composition containing a polyester including at least a lactic acid unit, a dibasic acid unit, and a glycol unit, a tackifier resin, and a crosslinking agent, wherein the dibasic acid unit includes a dimer acid, the polyester has a weight average molecular weight of 20,000 to 200,000 and a glass transition temperature of -70 to -20°C as measured using a differential scanning calorimeter at a temperature rise rate of 20°C/minute, the polyester has a hydroxyl value of 1 to 60 mgKOH/g, the adhesive composition contains 10 to 70 parts by weight of the tackifier resin based on 100 parts by weight of the polyester, and the pressure-sensitive adhesive layer has a gel fraction of 50 to 90% by weight.

    摘要： An object of the present invention is to provide a polylactic acid-based decorative body that is polylactic acid resin-based and has a synthetic resin coating film at the uppermost layer so that: the disadvantage of polylactic acid resin can be compensated for; environmental loading can be reduced; a good appearance can be provided; its surface can be prevented from being affected or deteriorated by sweat, hand cream, or the like on the hand of the user; and it can be used in electronic equipment cases. The polylactic acid-based decorative body according to the present invention includes a polylactic acid resin-containing substrate, a polylactic acid resin-containing adhesion layer provided on the substrate, and at least one functional layer that is formed on the adhesion layer by applying an acrylic urethane coating composition, wherein in the acrylic urethane coating composition, the molar ratio of OH groups in an acrylic resin to NCO groups in a polyfunctional isocyanate is 1:4 to 1:6.

    摘要： Provided is a masking pressure-sensitive adhesive tape that is produced using a plant-derived raw material, is global environmentally-friendly, has stable adherability to adherends and its own backside, has low adhesive strength to its own backside when unwound at high speed, and has good workability (peelability). The masking pressure-sensitive adhesive tape includes a substrate and a pressure-sensitive adhesive layer that is provided on at least one side of the substrate and made from a polyester-based pressure-sensitive adhesive composition containing a polyester including at least a lactic acid unit, a dibasic acid unit, and a glycol unit, and a crosslinking agent, wherein the dibasic acid unit includes a dimer acid, the polyester has a weight average molecular weight of 20,000 to 200,000 and a glass transition temperature of -70 to -20°C as measured using a differential scanning calorimeter at a temperature rise rate of 20°C/minute, the polyester has a hydroxyl value of 1 to 60 mgKOH/g, and the pressure-sensitive adhesive layer has a gel fraction of 40 to 90% by weight.
