An article with a hollow body defined by a wall with an inner surface and an outer surface. The wall is comprised of 2 or more layers including a first skin layer with effect pigments and an opaque core. In some examples, the effect pigment can be a special effect pigment adapted to produce at least one interference color.

A blow molded monolayer article. The article has a hollow body defined by a wall. The wall has one or more regions comprising a first composition and one or more regions formed by a second composition.

A laminate nanomold includes a layer of perfluoropolyether defining a cavity that has a predetermined shape and a support layer coupled with the layer of perfluoropolyether. The laminate can also include a tie-layer coupling the layer of perfluoropolyether with the support layer. The tie-layer can also include a photocurable component and a thermal curable component. The cavity can have a broadest dimension of less than 500 nanometers.

A water-soluble film contains a polyvinyl alcohol resin (A), and has a complete dissolution time (T) and a curl area percentage (S), wherein a product (TS) of the complete dissolution time (T) and the curl area percentage (S) satisfies the following expression (1):
1000(Complete dissolution time (T))(Curl area percentage (S))7000(1)
The water-soluble film satisfies contradictory property requirements, i.e., satisfactory solubility and curl suppressing property, for example, even if being formed by using an acid-modified PVA resin.

Disclosed is a mould for a cosmetic product, including at least one hollow body having a chamber delimited by a wall with a moulding surface and an access opening, the chamber being adapted to receive the cosmetic product in liquid form, the body possibly including a margin, extending radially from the opening and at least partially around it, the mould further including, possibly, a rigid support component, around the perimeter of the hollow body, the mould being characterised in that at least the body is made of a flexible polymer material. Also disclosed is a process for the manufacture of a cosmetic product using the aforementioned mould.

A film having excellent optical homogeneity, which is suitably used as an optical film in an image display device, and a method for manufacturing the same. Moreover, an evaluation method which can evaluate the optical homogeneity of the film with a higher precision than in conventional evaluation methods is provided. A film that is a cast film containing a resin having a weight average molecular weight of 200,000 or more, wherein, when line profiles in a direction h and a direction v which are orthogonal to each other in a film inverse space image obtained by Fourier transforming a projection image obtained by a projection method using the cast film are a line profile h and a line profile v.

Methods and apparatus for positioning a structure on a polymer layer are described. A method may involve forming a first polymer layer. The method may further involve positioning, by an apparatus, a structure on the first polymer layer, where the apparatus comprises a rod having a first end that supports the structure as the structure is being positioned and a plunger located around the first end of the rod that presses the structure onto the first polymer layer as the structure is being positioned. And the method may involve forming a second polymer layer over the first polymer layer and the structure, where the first polymer layer defines a first side of a body-mountable device and the second polymer layer defines a second side of the body-mountable device opposite the first side.
