A separator roll etc. capable of reducing meandering is provided. The separator roll includes a core and a battery separator wound around the core. The core has an axis hole along a central axis of the core. A value, obtained by dividing a difference between a diameter of the core and a diameter of the axis hole by a width of the core in a direction of the central axis, is not less than 0.3 and not more than 1.5.

Separator roll and method of producing same

An acrylic film for a lens substrate is provided. The film has a thickness of 400 &#x3bc;m or thinner and comprises a layer of a resin composition comprising a methacrylic resin and rubber particles dispersed therein. A lens layer can be placed on the acrylic film to produce a lens film excellent in light fastness. The lens film may be laminated on a resin sheet to produce a lens sheet suppressing its deformation such as warping or sagging.

Acrylic film for lens substrate, lens film using the same lens sheet

There are provided (I) a laminate comprising: (i) a resin layer (A), which comprises a layer containing a propylene resin (a), (ii) a resin layer (B), which comprises a layer containing an acrylic resin (b) having a flexural modulus of from 100 to 1500 MPa, and (iii) a resin layer (C), which comprises a layer containing an acrylic resin (c), wherein the resin layers (A), (B) and (C) are laminated in this order, (II) a structure comprising said laminate, and (III) a process for producing said structure.

Laminate

The present invention provides an acrylic resin laminated film comprising a first layer comprising an acrylic resin and a second layer comprising a resin composition comprising (a) an acrylic resin and an olefin-based copolymer obtained by copolymerization of an olefin and at least one monomer selected from the group consisting of unsaturated carboxylic acids, unsaturated carboxylates, unsaturated carboxylic anhydrides and vinyl acetate, or (b) an olefin-based copolymer obtained by copolymerization of an olefin and a monomer having glycidyl group in a side chain, which has excellent melt-adhesion to both of an acrylic resin and a polyolefin-based resin and additionally, and a laminated article which, due to the use of this acrylic resin laminated film, has excellent transparency, ornamental property, surface hardness, weather-resistance, oil-resistance and the like which are characteristics of an acrylic-resin constituting the most outer surface, and additionally, manifests excellent molding processability, recycling property, punching and bending processability, heat-resistance, cold-resistance and the like which are characteristics of a polyolefin-based resin which is a substrate.
