Process for making paper with improved filler retention and opacity while maintaining wet tensile strength

A process is disclosed for making paper having improved filler retention and opacity. The process includes the step of adding Additive A and Additive B to a slurry in a wet end of a paper machine wherein the slurry comprises pulp and a filler. Additive A is a wet strength agent. Additive B is an anionic polymer having a charge density from about −3000 to about −7000 ueq/g on a dry basis when measured in a buffer having a pH of about 6. Additive B also has a weight average molecular weight of from about 150,000 to about 1,000,000, Daltons.

STAINABLE SURFACE
20210009841 · 2021-01-14 · ·

The invention relates to a method for producing a color-changeable decorative surface. In order to provide a decorative surface that can be changed in a particularly simple manner in terms of its coloring by the end consumer and which is particularly cost-effective and resistant, it is provided that at least one layer of a coating agent, which enables the absorption of color particles, is applied.

STAINABLE DECORATIVE BOARD
20210010203 · 2021-01-14 · ·

The invention relates to a method for producing a synthetic resin surface or lacquered surface with a variable color, having the steps of providing a support layer with a lower face and an upper face, impregnating the support layer with a liquid impregnant without using a pickling additive and at least drying the impregnated support layer. The aim of the invention is to provide a decorative surface, the coloring of which by the end consumer can be modified in a particularly simple manner and which is particularly inexpensive and resistant. This is achieved in that a layer of coating agent is deposited on the upper face of the support layer and is dried, and the support layer is then connected to a material, wherein the layer is cured in order to form an open-pore layer which is at least as transparent as possible upon drying and/or connecting to the upper face.
