20130022827 | Composition for Forming Film and Film Sheet - The present invention provides a composition for forming a film and its resultant film which has a high level of adhesiveness to a substrate and has good gas barrier properties. The composition for forming a film is prepared by adding a silane coupling agent to an aqueous dispersion liquid in which a cellulose nanofiber is dispersed in an aqueous medium. In addition, the composition for forming a film is also prepared by blending an aqueous dispersion liquid (a) which contains a cellulose nanofiber and has a pH 4-9 with a hydrolysis liquid (b) which contains alkoxysilane hydrolysates and has a pH 2-4 by a weight ratio of “cellulose nanofiber”/“alkoxysilane (in terms of SiO | 01-24-2013 |
20130260143 | LAMINATED BODY - The invention makes it possible to use a coating liquid of a fine cellulose fiber (a natural material) and to form a coated layer which can be used as a various-functions layer such as a gas barrier layer and water vapor barrier layer etc. by achieving good adhesiveness and coatability of the coating liquid, and as a result, provides a laminated material in which temporal degradation of a substrate and the fine cellulose fiber layer is prevented. The laminated body includes a substrate, an anchor layer arranged on a surface the substrate, and a fine cellulose fiber layer containing a fine cellulose fiber having a carboxy group, wherein the anchor layer contains at least one resin having a carboxy group, sulfonate group, amino group or hydroxyl group. | 10-03-2013 |
20140017430 | LAMINATE, MANUFACTURING METHOD AND SHAPED CONTAINER - Provided is a laminate having at least a base material and a fine cellulose layer which includes fine cellulose having a carboxyl group, the laminate characterized in being obtained by laminating two or more of the fine cellulose layer. Also provided is a method for manufacturing a laminate, comprising the steps of (1) coating the base material with a liquid dispersion that includes fine cellulose having a carboxyl group, (2) forming a fine cellulose layer by drying the liquid dispersion used for coating, and (3) laminating fine cellulose layers by repeating steps (1) and (2). | 01-16-2014 |
20140199541 | LAMINATE, METHOD FOR PRODUCING SAME, AND GAS BARRIER MATERIAL - A laminate having high adhesion between a fine cellulose layer and a base material, a method for producing the same, and a gas barrier material. The laminate is such that a fine cellulose layer containing fine cellulose having a carboxyl group is laminated on the base material, and a mixed layer in which the fine cellulose is mixed in the base material is further interposed between the base material and the fine cellulose layer. This laminate can be produced by coating the base material with a dispersion containing fine cellulose having a carboxyl group, swelling the base material with the thus coated dispersion, and drying the swollen base material and the coated dispersion. The laminate may also be produced by providing a swollen base material, coating the swollen base material with a dispersion containing fine cellulose having a carboxyl group, and drying the base material and the coated dispersion. | 07-17-2014 |
