摘要:
A pressure-sensitive adhesive product contains a substrate having formed on at least one surface thereof a pressure-sensitive adhesive layer, wherein the substrate is formed from a styrene-based resin composition and the pressure-sensitive adhesive layer is formed from an acrylic pressure-sensitive adhesive containing an acrylic polymer, a liquid paraffin, and a rosin-based tackifying resin. In the acrylic pressure-sensitive adhesive, the ratio of the liquid paraffin is preferably 6 to 50 parts by weight based on 100 parts by weight of the acrylic polymer and the ratio of the rosin-based tackifying resin is preferably 1 to 30 parts by weight based on 100 parts by weight of the acrylic polymer. The liquid paraffin may have a number-average molecular weight of 300 to 500 and may have a dynamic viscosity at 37.8°C of 6 to 80 mm 2 /second.

A printing apparatus includes a plate cylinder (10) having a relief plate (50) mounted on at least a part of an outer periphery of the plate cylinder and being operable to be rotationally driven about a shaft center, and an impression cylinder (20) having a rigid outer periphery and being operable to be rotationally driven about a shaft center parallel to the shaft center of the plate cylinder. The impression cylinder is adapted to be brought into pressure contact with the relief plate (50) via a sheet-like print object (S) fed between the plate cylinder and the impression cylinder. A cushioning sheet (40) is attachable to and detachable from the outer periphery of the impression cylinder. The cushioning sheet (40) is elastically deformable when being brought into pressure contact with the relief plate on the plate cylinder via the print object. The cushioning sheet is restorable when being separated from the relief plate on the plate cylinder.

摘要:
The pressure-sensitive adhesive product has a constitution wherein a pressure-sensitive adhesive layer is formed on at least one surface of a substrate, the substrate being formed from a resin composition containing an acrylonitrile-styrene copolymer and an acrylonitrile-styrene-acrylic rubber copolymer as main components and the weight ratio of the acrylonitrile-styrene copolymer to the acrylonitrile-styrene-acrylic rubber copolymer being 90/10 to 20/80. The above resin composition preferably has a form where the acrylonitrile-styrene-acrylic rubber copolymer is dispersed in the acrylonitrile-styrene copolymer.
摘要:
The present invention relates to a laser marking label for forming patterns by a process including the step of selectively destroying a recording layer with a laser beam and exposing lower layers, wherein the laser marking label contains at least a recording layer (2), a backing layer (3), a ground layer (4), a shielding layer (5), and an adhesive layer (6), in this order, wherein each of the layers is directly or indirectly laminated. According to the laser marking label of the present invention, patterns of a workpiece or an opening part can be covered for the designing property and prevention of erroneous operation of an optical sensor, and the label can also serve as a display, in other words, excellent shielding ability in both line image portions and non-line image portions can be provided. Also at the same time, a display of white line images on a black background, sufficient durability and sufficient resolution can be realized.
