The invention relates to a method for manufacturing thermoplastic poly(vinyl alcohol) derivative in a melt state reaction and a product thereof, wherein the method thermoplastic poly(vinyl alcohol) that has been dried is heated and admixed with an organic acid anhydride that has a catenated carbon structure which ends into a vinyl group, such that a mixture is obtained which is above the melting point of the mixture, thereby causing an ester bond forming condensation reaction in a melt state, wherein at least some of the organic acid anhydride reacts with hydroxyl groups of the thermoplastic poly(vinyl alcohol), such that reaction product is formed which contains carboxylic acid residue and thermoplastic poly(vinyl alcohol) derivative which contains ester bonded pendant chains of which at least some end into vinyl groups. The invention further relates to a method for manufacturing a paper substrate and a product thereof, which contains a primer layer that contains the reaction product.

A recyclable material and packaging is provided. The material includes paper with weight of between 35 g/m.sup.2 and 160 g/m.sup.2 and maximum thickness of the overall material, excluding the heat-sealing overlapping areas, of between 35 μm and 310 μm.

The present invention refers to a coated transfer paper for receiving digital printing inks, maintaining high tonal fidelity, the paper being treated to transfer the image when it contacts a receiving base, preventing transfer to surfaces that do not have the receiving base. In addition, the invention relates to a printing method that combines the techniques of screen printing and digital printing, using the transfer paper.

An object of the present invention is to provide a transfer paper which allows smooth removal of a printed transfer paper from a design-printed fabric before steaming; and is unlikely to cause problems such as partial missing, color unevenness, color-development deterioration, etc. of the design on the fabric. Provided is a transfer paper having a substrate and one or more coating layers, the substrate having a base paper and one or more nonaqueous resin layers on one side of the base paper, the one or more coating layers being located on the one or more nonaqueous resin layers, the coating layer located outermost from the substrate, that is, the outermost coating layer, at least comprising a water-soluble polyester resin, a carboxylic acid-modified polyvinyl alcohol resin, an acrylic resin, a starch, and a white pigment, the acrylic resin having a glass transition point (Tg) of 0° C. to 45° C. and a minimum film forming temperature (MFT) of 0° C. to 50° C.

Methods for producing biodegradable and recyclable barrier paper laminate comprising an inorganic barrier layer against permeation.

Methods for producing biodegradable and recyclable barrier paper laminate comprising an inorganic barrier layer against permeation.

Highly transparent (up to 92% light transmittance) wood composites have been developed. The process of fabricating the transparent wood composites includes lignin removal followed by index-matching polymer infiltration resulted in fabrication of the transparent wood composites with preserved naturally aligned nanoscale fibers. The thickness of the transparent wood composite can be tailored by controlling the thickness of the initial wood substrate. The optical transmittance can be tailored by selecting infiltrating polymers with different refractive indices. The transparent wood composites have a range of applications in biodegradable electronics, optoelectronics, as well as structural and energy efficient building materials. By coating the transparent wood composite layer on the surface of GaAs thin film solar cell, an 18% enhancement in the overall energy conversion efficiency has been attained.
