Patent ID: 8420735

Claim:
A modified microfibrillated cellulose wherein a hydrolyzable-silyl-group-containing resin (A) bonds to or adheres to a cellulose surface, the modified microfibrillated cellulose has a silicon content of 0.01 to 0.5 atomic percent derived from the hydrolyzable-silyl-group-containing resin (A), the hydrolyzable-silyl-group-containing resin (A) is a (meth)acrylic resin prepared by (co)polymerizing 1% to 100% by weight of a hydrolyzable-silyl-group-containing unsaturated monomer that is a compound having at least one hydrolyzable silyl group and at least one polymerizable double bond in a single molecule, 99% to 0% by weight of an acrylic monomer, and 0% to 80% by weight of another polymerizable unsaturated monomer that is a polymerizable unsaturated compound that is not the hydrolyzable-silyl-group-containing unsaturated monomer or the acrylic monomer, and the hydrolyzable silyl group is a silicon-containing group represented by RnSiX4-n (where R represents at least one organic group selected from the group consisting of an alkyl group, an aryl group, and an unsaturated fatty acid residue that have 1 to 10 carbon atoms and optionally have a substituent; X represents an alkoxy group; n represents an integer of 0 to 3; and R and X may be the same as or different from each other).
