    摘要： A surface protective pressure-sensitive adhesive sheet being less staining, less likely to trap air bubbles, and attachable by hand and having good wetting ability on an adherend and having an appropriate level of adherability and light peelability is provided, which includes a pressure-sensitive adhesive layer obtained by crosslinking a polymer-containing pressure-sensitive adhesive composition, wherein the pressure-sensitive adhesive layer has a surface that has a hardness of 0.1 MPa or more and a load curve with a minimum load of -0.3 µN or less as measured by nanoindentation, and which has a residual adhesive strength of 50 % or more, wherein the residual adhesive strength is calculated from the formula: residual adhesive strength (%) = 100 x [(adhesive strength B)/(adhesive strength A)], wherein adhesive strength A is the adhesive strength measured by a process including bonding a standard pressure-sensitive adhesive tape to the surface of an adherend and then peeling off the pressure-sensitive adhesive tape from the adherend surface, and adhesive strength B is the adhesive strength measured by a process including bonding the surface of the pressure-sensitive adhesive layer of the protective pressure-sensitive adhesive sheet to the surface of an adherend, then peeling off the protective pressure-sensitive adhesive sheet from the adherend surface, further bonding a standard pressure-sensitive adhesive tape to the adherend surface from which the protective pressure-sensitive adhesive sheet has been peeled off, and then peeling off the pressure-sensitive adhesive tape from the adherend surface.

    摘要： Efficiently produced is a release liner including a plant-derived film as a substrate and having a good appearance, releasability, and adhesion. A method according to the present invention produces a release liner having a plant-derived film substrate and, on at least one side thereof, a release coat layer derived from a thermosetting silicone resin. The method includes the steps as follows:
    Step A of applying a thermosetting silicone release agent to at least one side of a plant-derived film substrate, the release agent containing 100 parts by weight of a thermosetting silicone resin and 0.05 to 0.55 part by weight of a curing catalyst;
    Step B of drying at 40°C to 90°C for 10 to 60 seconds after Step A;
    Step C of applying an ultraviolet ray at 50 to 300 mJ/cm 2 after Step B; and
    Step D of aging at 30°C to 70°C for 12 to 240 hours after Step C.

    摘要： Disclosed is a polylactic acid-based film or sheet as a resin film or sheet including a polylactic acid (A). The film or sheet has a melt endotherm ΔHc' of 10 J/g or more, where ΔHc' is of a region crystallized upon film formation and specified by following Expression (1): ΔHcʹ = ΔHm - ΔHc
    wherein ΔHc represents an exotherm (J/g) associated with crystallization of the film or sheet in a temperature rise process after film formation; and ΔHm represents an endotherm (J/g) associated with subsequent melting of the film or sheet, each determined by DSC. The film or sheet has a tear strength of 2.5 N/mm or more both in a machine direction (MD) and a transverse direction (TD). The polylactic acid-based resin film or sheet is resistant to melting and deformation even at an elevated temperature higher than 100°C and is resistant to breaking and tearing typically when the film or sheet is wound into a roll upon production or working.
