With inkjet method an ink-receiving layer recording sheet and the ink receiving layer coating solution

摘要

PROBLEM TO BE SOLVED: To improve water resistance, weatherability and and anti-fading property, and also improve strength by setting the pore diameter of an ink receptive layer in the range of two specific values, and setting the pore volume of each pore diameter in the range of each specific value. ;SOLUTION: The pore volume of a pore diameter of 3.4-30 nm having an ink receptive layer formed on a base sheet in the constitution of oxide particles and a binder is set on 0.2-1.8 ml/g, but if it is set on 0.5-1.5 ml/g, it is better. Although the pore volume of the pore diameter of 30-2000 nm is set on 0.1-1.5 ml/g, if it is set 0.2-1.2 ml/g, it is better. If the pore volume of the pore diameter of 3.4-30 nm is less than 0.2 ml/g, bleeding due to small ink absorption capacity is generated, and if it is larger than 1.8 ml/g, the fastness of dye and the strength of the ink receptive layer sometimes become lower. If the pore volume of 30-2000 nm is less than 0.1 ml/g, colors of the printed matter may sometimes come off, and if it is larger than 1.5 ml/g, the sharpness of images may sometimes be lost.;COPYRIGHT: (C)1999,JPO
