Title:
INK JET RECORDING FILLER AND RECORDING PAPER
Document Type and Number:
Japanese Patent JP3802950
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ink jet recording filler wherein resistance to discoloration of an ink image, resistance to yellowing of paper, and its smoothness are excellent, and application in high density can be performed.
SOLUTION: An ink jet recording filler is composed of a porous globular silicate particle wherein that is composed of silicate of a composition of SiO2: MO=99.5:0.5 to 70:30 expressed by wt. ratio in oxide standard (in the formula, M represents periodic group D metals), the silicate is an X-ray diffractively amorphous or fine lamellar crystal, each particle is an independent distinct globular particle, a sphericity expressed by a ratio (DS/Dl) of minor axis (DS) to major axis (Dl) is within a ranqe of 0.8 to 1.0, and a particle size measured with an electron microscope is within a range of 0.3 to 20μm.
