摘要:
Formulations comprising novel porous metal oxide particles and binder are particularly suitable for ink receptive coatings, e.g., for ink jet papers and films. The metal oxide particles used in this application have a porous structure that differs significantly from the nonporous silica colloids. The particles have a median particle size in the range of about 0.05 to about 3 microns and porosity such that when an aqueous dispersion of the particles is dried at least 0.5 cc/g of pore volume is from pores having a pore size of 600 Å or less. The particles also have a viscosity derived pore volume of at least 0.5 cc/g.
摘要:
A coating composition comprising relatively low alkali cationic colloidal silicas and ink jet recording sheets prepared from such coatings is described. The coating comprises binder and cationic colloidal silica preferably having an average particle size in the range of about 1 to about 300 nanometers and which has a solids to alkali metal ratio of at least the sum of AW(−0.013SSA+9), AW being the atomic weight of alkali metal present in the colloidal silica and SSA being the specific surface area of the silica. It has been discovered that if the alkali metal, e.g., sodium, content of colloidal silica is reduced, coatings prepared from such colloidal silica and applied to conventional ink jet recording sheet supports provide a specular gloss of at least 30 at 60° C., even at a relatively high silica solids to binder solids ratio of 1:1 or greater.

摘要:
A coating composition comprising cationic colloidal silicas and ink jet recording sheets prepared from such coatings is described. The coating comprises binder and polydispersed cationic colloidal silica. The cationic colloidal silica preferably has an average particle size in the range of about 1 to about 300 nanometers. It has been discovered that if a cationic polydispersed colloidal silica is employed in a glossy coating formulation, the coating provides a specular gloss of at least 30 at 60° C., even at a relatively high silica solids to binder solids ratio of 1:1 or greater, but also a coating having good to excellent printability characteristics.
摘要:
Epoxy-polymerized tannin/inorganic oxide composite particles are obtained by polymerizing the tannin with a polyepoxy crosslinking agent in situ on inorganic oxide particles. The compositions of the invention are capable of achieving the performance of tannin in beverage treatment applications without tannin's associated filtration disadvantages.
