AQUEOUS PAINT AND POTTERIES AND PAINTING METHOD
To provide an aqueous paint which can suppress color unevenness or coating unevenness, is difficult to dissolve in a glaze and has excellent fixability, and potteries therewith.SOLUTION: This problem is solved by an aqueous coating comprising: a colored substrate; a first cellulose nanofiber having a lignin content of 20 to 40 mass% and water retention of 150 to 300%; and a second cellulose nanofiber having viscosity higher than that of the first cellulose nanofiber, in which the B-type viscosity is 600 cps or larger, furthermore, the problem is solved by potteries or glass devices including a base substrate having a main component of a surface being silicic acid and a silicic acid compound, the aqueous paint being drawn on the base substrate.SELECTED DRAWING: Figure 1
【課題】色ムラや塗りムラを抑制でき、釉薬に溶け出し難く、定着性に優れる水性塗料とこれを備えた陶磁器類等を課題とする。【解決手段】着色素材と、リグニン含有量が２０〜４０質量％、保水度が１５０〜３００％である第１セルロースナノファイバーと、前記第１セルロースナノファイバーよりも高い粘度を有する第２セルロースナノファイバーとが含有され、Ｂ型粘度が６００ｃｐｓ以上である、ことを特徴とする水性塗料により解決され、また、表面の主成分がケイ酸又はケイ酸化合物である素地に、同水性塗料が描画された陶磁器又はガラス器等により解決される。【選択図】図１
