Abstract
Official abstract text for this publication.
A sheet forming binder includes a first powder and a second powder having a larger volume average particle size than the first powder. The proportion of the first powder is 10.0% by mass or more relative to the total mass of the first powder and the second powder.
First claim
Opening claim text (preview).
What is claimed is: 1. A sheet forming binder comprising: a first powder; and a second powder having a larger volume average particle size than the first powder, wherein the proportion of the first powder is 10.0% by mass or more relative to the total mass of the first powder and the second powder, the first powder is in a state where particles of an inorganic pigment are bound to each other with a resin, and the second powder is in a state where particles of an inorganic pigment are bound to each other with a resin. 2. The sheet forming binder according to claim 1 , wherein the first powder contains a fluorescent brightening agent. 3. The sheet forming binder according to claim 2 , wherein the first powder contains the fluorescent brightening agent with a content of 1% by mass or less relative to the total mass of the first powder. 4. The sheet forming binder according to claim 1 , wherein the first powder has a volume average particle size of 5.0 μm or less, and the second powder has a volume average particle size of 10.0 μm or more. 5. The sheet forming binder according to claim 1 , wherein the first powder contains titanium dioxide as the inorganic pigment with a content of 30.0% by mass or more. 6. The sheet forming binder according to claim 1 , wherein the second powder contains titanium dioxide as the inorganic pigment with a content of 8.0% by mass or less.
