摘要:
This invention pertains to an ink jet recording medium comprises a flexible substrate and a coating composition coated on at least one surface of the substrate, wherein the coating composition comprises the product formed from the contact between fumed silica particles and at least one aminoorganosiloxane. The invention also pertains to a method for the preparation of such an ink jet recording medium and to methods for the preparation of a coating composition and a dispersion useful in the preparation of such an ink jet recording medium.
摘要:
The present invention provides a recording medium comprising a substrate having a glossy coating thereon, wherein the glossy coating comprises a binder and first and second groups of particles, wherein: (a) the first group comprises metal oxide particles, wherein the metal oxide particles are aggregates of smaller, primary particles, (b) the mean diameter of the primary particles is less than about 100 nm, (c) the mean diameter of the aggregates is from about 100 nm to about 500 nm, (d) the mean diameter of the particles in the second group is less than about 50% of the mean diameter of the aggregates in the first group, and (e) the ratio of particles in the first group to particles in the second group is from about 0.1:1 to about 10:1 by weight. The glossy coating of the inventive recording medium has an excellent rate of liquid absorption, a relatively high liquid absorption capacity, excellent adhesiveness, and a non-brittle, crack-resistant, glossy surface. Also provided is a method of preparing a recording medium and a coating composition useful in the preparation of a recording medium.

The present invention provides a recording medium comprising a substrate having a glossy coating thereon, wherein the glossy coating comprises cationic silica. The cationic silica comprises silica particles having a mean diameter of less than about 1 &mgr;m that have been contacted with at least one aluminum compound. The present invention also provides an aqueous dispersion of cationic silica, a coating composition comprising it, and methods of preparing the dispersion, coating composition, and recording medium.
摘要:
A method of passivating a CMP composition by dilution and determining the relationship between the extent of dilution and the static etch rate of copper. Such relationship may be used to control the CMP composition during the CMP polish to minimize the occurrence of dishing or other adverse planarization deficiencies in the polished copper, even in the presence of substantial levels of copper ions in the CMP composition and at the copper/CMP composition interface.

Chemical mechanical polishing (CMP) compositions and single CMP platen process for the removal of copper and barrier layer material from a microelectronic device substrate having same thereon. The process includes the in situ transformation of a copper removal CMP composition, which is used to selectively remove and planarize copper, into a barrier removal CMP composition, which is used to selectively remove barrier layer material, on a single CMP platen pad.
