The present invention relates to a process for the preparation of films of conductive polymers, by the technique so-called roll-to-roll, which allows to obtain freestanding films having advantageous features such as toughness, flexibility, ability to adhere to different substrates, a submicron thickness and a very high ratio surface area/thickness; the present films are suitable for use in several technological applications, in particular for the development of biosensors, and in the production of flexible electronic components with large surface, suitable for wearable devices and also intended for contacting skin.

The disclosure provides post-production methods for functionalization of optical quality films produced by top tier manufactures. The methods disclosed herein allow for the incorporation of different additives into existing films.

Provided is a thermoplastic resin composition for an interior material of automobiles, comprising a biomass-derived resin. The thermoplastic resin composition for an interior material of automobiles uses a biomass-derived resin, which replaces a petroleum-based thermoplastic resin, so as to reduce the generation of CO2, thereby providing an environmentally friendly effect.

A resin composition includes a cellulose derivative in which at least one hydroxyl group is substituted with an acyl group, which has a weight average molecular weight of 10,000 to 75,000 and an average degree of substitution of the acyl group of 1.8 to 2.5, and which exhibits an amount (weight ratio) of an insoluble portion, when being dissolved in tetrahydrofuran (THF) at 25° C., of less than or equal to 5% by weight.

The present disclosure relates to an optical laminate or a reddening-resistant layer. The present disclosure can provide an optical laminate that does not cause a so-called reddening phenomenon even when driven or maintained under extremely harsh conditions (e.g., very high temperature conditions), or a reddening-resistant layer applied thereto.

The disclosure provides post-production methods for functionalization of optical quality films produced by top tier manufactures. The methods disclosed herein allow for the incorporation of different additives into existing films.

Multifunctional optically highly transparent films based on cellulose esters are disclosed, having the following components within a film a) cellulose esters preferably based on cellulose triacetate which can be processed into a highly transparent film with Haze value of < than 0.4% by virtue of a high degree of purity and optical quality and which is defined by the following properties b) at least one organic or inorganic material which acts as a plasticizer and as a spacer between the molecule chains of the cellulose esters and additionally introduced additives in a synergistically effective manner c) at least three organic or inorganic materials with a transmission influencing absorptive function in the wave length range of 300 nm to 2500 nm, the films having protective strain reducing function for the retina of the human eye.

Provided are NCC-based materials, as superb barrier materials for preventing oxygen and humidity from penetrating therethrough.

A coated, highly transparent film based on cellulose triacetate, is proposed that includes a) a support film acting as support layer and a cellulose triacetate or a mixture of cellulose esters and cellulose triacetate as main component, the cellulose triacetate or mixture being defined by a haze value of <0.5%, measured on the cellulose triacetate or mixture drawn out to a film after having been dissolved in dichloromethane or acetone, and b) a multi-functional coating applied in a coating solution to one or both sides of the support film. A dissolver medium can also be used as an enclosure medium. The highly transparent films of the invention can be used as window film, sunglasses film, laminating film, furniture foil, enclosing film, slide film for microscopy, cover slip replacement film and/or protective film, adhesive to glass, wood, metal, ceramic, cellulose derivative films or plastics following incipient dissolution or heat treatment.

A foamed, opacifying element is prepared to have a light-blocking value (LBV) of at least 4. A method is carried out in a specific order with a unique series of steps including: providing a unique foamable aqueous composition; aerating that foamable aqueous composition to a foam density of at least 0.1-0.5 g/cm.sup.3; disposing the foamed aqueous composition onto a surface of a porous substrate; drying the foamed aqueous composition without substantial curing of the binder material therein, to provide a dry foamed composition on the surface, without substantial curing; densifying the dry foamed composition to provide a dry opacifying layer in a foamed, opacifying element; and curing the dry opacifying layer in the foamed, opacifying element.
