Document Type and Number:
WIPO Patent Application WO2004106079
Kind Code:
A3
Abstract:
Aqueous, white mineral pigment-based coating compositions (P) comprising (A) white mineral pigment particles (A1) and (A2), wherein, referred to the dry forms, (A1) are colloidal, non-porous, white mineral pigment particles of an average particle size in the range of 5 to 80 nm, wherein > 99 % of the particles are of a particle size < 100 NM, AND (A2) are micro-porous, white mineral pigment particles of an average particle size in the range of 0.5 to 25 µm, wherein > 99 % of the particles are of a particle size in the range of 0.1 to 100 µm, (B) a binder, and (C) a cationic, crosslinked polymer obtainable by exhaustive reaction of at least one crosslinking at least difunctional amine (G) and optionally a monofunctional amine (H) with a chloroterminated addition product (F) of epichlorohydrin to an oligo-functional alcohol (E), and optionally (D) one or more formulation additives their production and use for coating, the coated substrates and their use, in particular as ink-jet recording substrates, especially for colour ink-jet printing.
