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.

The present invention relates to a transfer paper, which is: (i) a transfer paper without a coating layer, which comprises a pulp, a filler and an urea phosphate esterified starch, or (ii) a transfer paper having a coating layer, which comprises a base paper and one or more coating layer(s) provided on at least one side of the base paper, wherein an outermost coating layer positioned on the outermost side with respect to the base paper contains at least kaolin, calcium carbonate and a binder, wherein, () the base paper contains an urea phosphate esterified starch, or () the outermost coating layer contains an urea phosphate esterified starch.

According to the present invention, it is possible to provide a transfer paper excellent in image deterioration resistance, color development property, adhesion property and strike-through suppression property.

The invention relates to a supercalendered Kraft paper production for a release liner, which contains both non-recycled bleached chemical pulps and recycled pulp produced from release liner supercalendered Kraft paper. When highly specific raw material is used for recycling, the characteristics of the recycled pulp may be adjusted already upon recycling. The recycled pulp obtained from supercalendered Kraft paper that has been used as a substrate of a release liner may be used without further refining for manufacturing supercalendered Kraft paper. Excessive refining can thus be avoided and the compatibility of the recycled pulp may be optimized for supercalendered Kraft paper production. The non-recycled pulps may be refined less, as well. This leads to positive effects in supercalendered Kraft paper manufacturing process, such as improved dewatering and energy efficient drying. The produced paper demonstrates reduced shrinkage and improved dimensional stability, while maintaining sufficient quality for use as a substrate for a release liner. A supercalendered Kraft paper with improved sustainability is produced.

The invention relates to a wrapping material (1) for wrapping an article (10), which is based on glassine paper with a grammage in the range of 25 to 50 g/m.sup.2, wherein the wrapping material (1) is present in the form of a web. The web has i. a first side face (S1), ii. a second side face (S2) situated opposite the first side face (S1), iii. at least one web portion (B) having a first and a second outer region portion (2, 3) and inner region portions (4, 5, 6, 7, 8), wherein the inner region portions are arranged between the outer region portions (2, 3).

A high-transparence fiberglass paper includes vegetable parchment which is successively coated with a base layer, a second layer and a protective layer on both sides. The base layer and protective layer are prepared using water-based paints, while the second layer is prepared using UV ink through curing. The transparency and surface smoothness of the fiber is thereby greatly improved. Through treatment on the both surfaces, the paper can be processed into a light and smooth paper, with a surface smoothness of both sides more than 200 s, just like hyaline paper.
