A packaging paper with a transparent zone, wherein the packaging paper and the zone are made from one cellulose layer and wherein the transparent zone comprises a coating layer material applied to the packaging paper, wherein the coating layer material comprises an oily compound such as a paraffin or vegetable oil.

A decorative sheet that has good scratch resistance and provides a soft and supple feel is provided. In the decorative sheet (1), a surface of the surface protective layer (5) is provided with asperities including ridge portions. In a power spectrum image obtained by applying a two-dimensional fast Fourier transform to their surface shape image, when the average luminance in the spatial frequency range of 95 to 105 cycles / mm is defined as P_100, the average luminance in the spatial frequency range of 195 to 205 cycles / mm is defined as P_200, the average luminance in the spatial frequency range of 695 to 705 cycles / mm is defined as P_700, and the ratio of the difference between P_100 and P_700 to the difference between P_200 and P_700 is defined as Rt_P, the average of Rt_P is within the range of 1.57 to 1.82. The surface protective layer contains 100 parts by mass of a cured resin and 3 to 11 parts by mass of particles with an average particle size of 3 µm or more, and has a thickness of 2 to 18 µm and a gloss less than 10.

This invention discloses a carbonless copy paper and its preparation process, belonging to the field of printing application technology of biomass conversion materials. The preparation process of the carbonless copy paper includes the following steps: pretreatment of the base paper, preparation of the surface coating of the middle and bottom paper, and preparation of the back coating of the middle and top paper. The beneficial effects of this invention are: setting a brittle oxygen-barrier micro-coating layer, forming a dense oxygen barrier film layer under normal conditions, isolating external oxygen and pressure, preventing premature breakage of microcapsules, achieving accurate color development under pressure, and the self-locking function of oxygen curing makes the microcapsules difficult to break, or even hard to break. In the area where the color has already developed, a protective layer is formed through the above structure to avoid the later breakage of microcapsules due to external force or easy migration and smudging of the dye in the font, and the gradual fading of the writing after long-term storage.

The invention relates to a nano-embossed tipping paper (1) which comprises a coating layer (2) containing nitrocellulose or ethyl cellulose, wherein the coating layer (2) is either a clear coating layer or a coloured coating layer and is provided with a nanostructure by means of mechanical embossing.

The present invention relates to a barrier film for a cellulose-based material, said barrier film comprising at least one microfibrillated cellulose layer (MFC layer), wherein said MFC layer comprises a three-dimensional (3D) pattern.

A coated panel comprises at least a substrate (2) and a top layer applied on the substrate (3). The top layer (3) comprises at least a decor layer (4), a translucent or transparent wear layer (5), and optionally a backing layer. The wear layer (5) comprises - and preferably consists of - a thermally cured acrylate resin. Preferably, the thermal curing partially or completely cures the resin, preferably by a thermally initiated radical crosslinking reaction. The top layer comprises a relief.

A method for making a coated paper sheet, wherein the coated paper sheet comprises a paper sheet and a partially cured acrylate coating layer. The partially cured acrylate coating layer is provided for being at least partially cured in a thermal pressing operation. The method comprises the steps of providing a paper sheet; and applying a coating composition onto the paper sheet thereby obtaining a coating layer on the paper sheet. The coating composition comprises at least an acrylate resin, one or more components that comprise free hydroxyl groups, one or more components that comprise free isocyanate groups, and optionally one or more thermoinitiators. The method comprises the step of gelling the coating composition on the paper sheet to a non-viscous state; and such that the acrylate coating layer is a partially cured coating layer.
