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&#xb0; C. of 6 to 80 mm/second.

Pressure-sensitive adhesive product

A method is described for preparing labels from blank stock material comprising printing on demand label information onto a substrate which has a pressure sensitive layer on one surface having relatively low adhesion to the opposite surface of the substrate to be printed and which has been rolled so that the adhesive layer adheres to the surface of the substrate to be printed.

Production method of linerless label

A peel-off developable pattern sheet comprising a transparent flexible substrate having thereon a pattern comprising a photopolymerizable color image-forming material layer and a process for producing a monochromatic or multi-color patterned display element by making use of the pattern sheet(s) are disclosed. A patterned display element can be produced in a continuous manner in an organic solvent-free working environment. The formed pattern has excellent sharpness and well-controlled surface properties.
