Abstract
Official abstract text for this publication.
Ceramics are capable of reducing color irregularities and uneven coating, hard to dissolve into glaze, and excellent in fixation. A water-based paint contains a coloring material, first cellulose nanofibers having a lignin content of 20 to 40 mass % and a water retention of 150 to 300%, and second cellulose nanofibers having a higher viscosity compared to the first cellulose nanofibers, and the water-based paint has a B-type viscosity of 600 cps or higher. Ceramic ware or glassware or the like having painting made on a green body of which surface is formed of silicic acid or silicate compound as a main component, with the water-based paint.
First claim
Opening claim text (preview).
The invention claimed is: 1. A water-based paint comprising: a coloring base material; first cellulose nanofibers having a lignin content of 20 to 40 mass % and a water retention of 150 to 300%; and second cellulose nanofibers made from chemical pulp and having a higher B-type viscosity compared to the first cellulose nanofibers, as measured in a form of an aqueous dispersion of cellulose nanofibers at 1% solid concentration, wherein the water-based paint has a B-type viscosity of 600 cps or higher, and wherein a mass ratio of the first cellulose nanofibers to the second cellulose nanofibers ranges from 99:1 to 51:49. 2. The water-based paint according to claim 1 , wherein a content of the second cellulose nanofibers is 0.02 to 1.9 mass %. 3. The water-based paint according to claim 1 , wherein a water retention of the second cellulose nanofibers is 250 to 400%.
