Abstract: A base film 2 for a dicing sheet is provided which can suppress dicing debris from generating during the dicing of a cut object without imparting physical energy, such as electron beam or ³ ray. The base film 2 for a dicing sheet comprises a resin layer (A). The resin layer (A) comprises: a norbornene-based resin (a1) that is a thermoplastic resin having a norbornene-based compound as at least one type of monomer; and an olefin-based thermoplastic resin (a2) other than the norbornene-based resin (a1). The norbornene-based resin (a1) in the resin layer (A) has a content of more than 3.0 mass%. A dicing sheet 1 is also provided which comprises: the base film 2 for a dicing sheet; and a pressure-sensitive adhesive layer 3 placed on a surface of the film at the resin layer (A) side.

Abstract: It is an object to provide an optical recording medium-producing sheet that enables a protective layer or stamper-receiving layer to be formed easily and inexpensively and gives a good yield. A composition having an energy ray-curable component as a principal component thereof is applied onto a substrate 12, a coating layer thus obtained is irradiated with energy rays so as to semi-cure the energy ray-curable component, thus forming an energy ray-curable layer 11 having an adhesive strength of not less than 10 mN/25mm, and then a substrate 12' is superposed onto the energy ray-curable layer 11, whereby an optical recording medium-(optical disk-) producing sheet 1 is obtained.

Abstract: A dicing sheet base film (2) includes a resin layer (A). The resin layer (A) contains: a polyethylene (a1) that has a density of 0.900 g/cm 3 or more; and a styrene-based elastomer (a2). The polyethylene (a1) has a content of 50 mass% or more and 90 mass% or less to a total resin component contained in the resin layer (A), while the styrene-based elastomer (a2) has a content of 10 mass% or more and 50 mass% or less to the total resin component. The dicing sheet base film (2) suppresses the occurrence of dicing debris during the dicing of a cut object without imparting physical energy such as electron rays and ³ rays, and has sufficient expandability in the expanding process.
