The present invention provides an optical laminated body having a patterning polarizer layer in which a more complicated pattern can be set. The optical laminated bodyA of the present invention has a patterning polarizer layerA having at least two polarizing regionsA andA having different single transmittances, and a substrateA. The two polarizing regionsA andA are different in thickness.

An inner deckle for a die includes a shaft-shaped deckle main body and a sheet- or film-shaped deckle auxiliary portion extending from the deckle main body. The inner deckle is arranged at each end of a die. The die includes a die piece and is formed with a manifold and a slit. The deckle main body includes a seal reinforcing portion. A liquid material is supplied into the manifold. The seal reinforcing portion includes at least one sealing member having two or more films. The films slide and are simultaneously elastically deformed against an inner wall of the manifold when a position of the inner deckle is moved with respect to the die. The films cooperate with each other and are closely attached to the inner wall by an elastic restoring force when the position of the inner deckle is fixed with respect to the die.

Provided is double-faced adhesive tape joining apparatus that allows accurate joining of a double-faced adhesive tape on a tape joining surface of a workpiece in a curved or bent shape with no damage on a surface of a separator joined to the double-faced adhesive tape and no floating of the separator. Specifically, a hand-operable base includes a tape guide for guiding the double-faced adhesive tape successively supplied, and a joining head for pressing against the joining surface of the workpiece the double-faced adhesive tape supplied to a front end of the base. The base and the joining head are configured as to rotate relatively about a support axis toward a longitudinal tape direction.

Disclosed is a method for joining two strips, where the two strips each include a laminate of a release liner and a pressure-sensitive adhesive layer, and the release liner extends from the corresponding pressure-sensitive adhesive layer in a longitudinal end region of at least one of the two strips. The method includes butting cross-sections of longitudinal ends of the pressure-sensitive adhesive layers of the two strips to bond the two pressure-sensitive adhesive layers; and superposing end regions of the release liners of the two strips and fixing the release liners so that surfaces of the release liners in portions at least 1 mm long inward from the longitudinal ends are not in contact with surfaces of the pressure-sensitive adhesive layers. This method gives a continuous strip from which the release liner can be smoothly removed without 'binding' even at the joint.

The present invention relates to a process for producing a pressure-sensitive adhesive layer, which includes irradiating a photopolymerizable acrylic pressure-sensitive adhesive composition layer provided between two films with an active energy beam to polymerize the photopolymerizable acrylic pressure-sensitive adhesive composition layer, in which the polymerization is performed while a layer of a composition for preventing polymerization inhibition which is curable with an active energy beam in the atmosphere is provided on a side surface of the photopolymerizable acrylic pressure-sensitive adhesive composition layer. According to the process for producing a pressure-sensitive adhesive layer of the present invention, owing to the construction as discussed above, it is possible to reuse a film. Moreover, it is possible to prevent a lowering in the cohesive force in the side surface of the thus formed pressure-sensitive adhesive composition layer caused by a lowering in the polymerization degree in the side surface of the photopolymerizable acrylic pressure-sensitive adhesive composition layer during the photopolymerization.
