摘要:
A method for manufacturing decorative laminates including the steps of: a) impregnating a paper substrate with a thermosetting resin by submersion of the paper substrate in a bath of thermosetting resin; b) applying on the thermosetting resin impregnated paper substrate an ink acceptance layer containing an inorganic pigment P and a polymeric binder B having a weight ratio P/B of inorganic pigment to polymeric binder of larger than 1.5; c) jetting on the ink acceptance layer a colour pattern with one or more aqueous pigmented inkjet inks and/or organic solvent based pigmented inkjet inks containing a colour pigment C; and d) heat pressing the thermosetting paper into a decorative laminate, wherein the weight ratio P/C of the inorganic pigment of the ink acceptance layer to the jetted colour pigment in the colour pattern is larger than 4.0.

摘要:
An inorganic particulate suspension may include a first kaolin having a shape factor of at least about 70, and a second kaolin having a shape factor less than or equal to about 20. The first kaolin and the second kaolin form a kaolin composition, which may have a content ratio of the first kaolin to the second kaolin ranging from about 90:10 to about 50:50. An inorganic particulate suspension may include a kaolin composition having a shape factor ranging from about 55 to about 75, wherein at least about 70% to about 90% by weight of the particles of the kaolin composition have an equivalent spherical diameter less than 2 microns. The suspension may have a Hercules viscosity ranging from about 600 rpm to about 700 rpm at 18.0 dyne using an “A” bob, and the suspension may have a solids content ranging from about 55% to about 75% solids.

摘要:
The invention provides a method for improving the effectiveness of colloidal silica. The method involves removing enough charged impurities from the colloid to prevent the charged particles from causing the colloid to become a viscous gel. The method however also involves not removing too many charged particles so the silica material doesn't gel by cross-linking with itself. This method is quite effective because it recognizes that materials that have accumulated during the formation of the colloid do perform an important function, but they can perform better at a lower concentration.
