MODIFIED ALUMINA HYDRATE PARTICLE AND METHOD FOR PRODUCING THE SAME, COATING LIQUID FOR FORMING INKJET RECEIVING LAYER CONTAINING MODIFIED ALUMINA HYDRATE PARTICLE, AND SUBSTRATE WITH RECEIVING LAYER

摘要

PPROBLEM TO BE SOLVED: To provide modified alumina hydrate particles having a predetermined average particle diameter, a coating liquid for forming an inkjet receiving layer excellent in stability, an inkjet receiving layer having excellent transparency, a low haze value, excellent scratch resistance and adhesiveness, and excellent bleeding resistance, drying property and water-proofing property when pigment ink or dye ink is used, and to provide a substrate with an inkjet receiving layer. PSOLUTION: The modified alumina hydrate particles comprise an alumina hydrate, having an average primary particle diameter (D1) ranging from 5 to 30 nm, an average secondary particle diameter (D2) ranging from 5 to 500 nm, and a ratio (D2)/(D1) of the average secondary particle diameter (D2) to the primary particle diameter (D1) ranging from 1 to 100; and the particles are modified with at least one kind of salt of group 2 metals in the periodical table.
